AI Detectors vs. Plagiarism Checkers

AI detectors and plagiarism checkers are both used to verify the originality and authenticity of a text, but they differ in terms of how they work and what they’re looking for.

AI detector

AI Detector or ChatGPT Detector

AI detectors try to find text that looks like it was generated by an AI writing tool, like ChatGPT. They do this by measuring specific characteristics of the text like sentence structure and length, word choice, and predictability — not by comparing it to a database of content.

Plagiarism report

Plagiarism Checker

Plagiarism checkers try to find text that is copied from a different source. They do this by comparing the text to a large database of web pages, news articles, journals, and so on, and detecting similarities — not by measuring specific characteristics of the text.

Scribbr & academic integrity

Scribbr is committed to protecting academic integrity. Our tools, like the AI Detector , Plagiarism Checker , and Citation Generator are designed to help students produce quality academic papers and prevent academic misconduct.

We make every effort to prevent our software from being used for fraudulent or manipulative purposes.

Your questions, answered

Scribbr’s AI Detectors can confidently detect most English texts generated by popular tools like ChatGPT, Gemini, and Copilot.

Our free AI detector can detect GPT2, GPT3, and GPT3.5 with average accuracy, while the Premium AI Detector has high accuracy and the ability to detect GPT4.

Our AI Detector can detect most texts generated by popular tools like ChatGPT and Bard. Unfortunately, we can’t guarantee 100% accuracy. The software works especially well with longer texts but can make mistakes if the AI output was prompted to be less predictable or was edited or paraphrased after being generated.

Our research into the best AI detectors indicates that no tool can provide complete accuracy; the highest accuracy we found was 84% in a premium tool or 68% in the best free tool.

The AI score is a percentage between 0% and 100%, indicating the likelihood that a text has been generated by AI.

No, Scribbr’s AI Detector will only give you a percentage between 0% and 100% that shows how much AI-generated content is in your text.

No. Our AI content checker can only inform you of AI-generated content. Our Plagiarism Checker can help prevent unintentional plagiarism in your writing.

How to Interpret the Result of AI Detection

To use our GPT checker, you won’t need to do any preparation work!

Take the 3 steps:

  • Copy and paste the text you want to be analyzed,
  • Click the button,
  • Follow the prompts to interpret the result.

Our AI detector doesn’t give a definitive answer. It’s only a free beta test that will be improved later. For now, it provides a preliminary conclusion and analyzes the provided text, implementing the color-coding system that you can see above the analysis.

It is you who decides whether the text is written by a human or AI:

  • Your text was likely generated by an AI if it is mostly red with some orange words. This means that the word choice of the whole document is nowhere near unique or unpredictable.
  • Your text looks unique and human-made if our GPT essay checker adds plenty of orange, green, and blue to the color palette.
  • 🔮 The Tool’s Benefits

🤖 Will AI Replace Human Writers?

✅ ai in essay writing.

  • 🕵 How do GPT checkers work?

Chat GPT in Essay Writing – the Shortcomings

  • The tool doesn’t know anything about what happened after 2021. Novel history is not its strong side. Sometimes it needs to be corrected about earlier events. For instance, request information about Heathrow Terminal 1 . The program will tell you it is functioning, although it has been closed since 2015.
  • The reliability of answers is questionable. AI takes information from the web which abounds in fake news, bias, and conspiracy theories.
  • References also need to be checked. The links that the tool generates are sometimes incorrect, and sometimes even fake.
  • Two AI generated essays on the same topic can be very similar. Although a plagiarism checker will likely consider the texts original, your teacher will easily see the same structure and arguments.
  • Chat GPT essay detectors are being actively developed now. Traditional plagiarism checkers are not good at finding texts made by ChatGPT. But this does not mean that an AI-generated piece cannot be detected at all.

🕵 How Do GPT Checkers Work?

An AI-generated text is too predictable. Its creation is based on the word frequency in each particular case.

Thus, its strong side (being life-like) makes it easily discernible for ChatGPT detectors.

Once again, conventional anti-plagiarism essay checkers won’t work there merely because this writing features originality. Meanwhile, it will be too similar to hundreds of other texts covering the same topic.

Here’s an everyday example. Two people give birth to a baby. When kids become adults, they are very much like their parents. But can we tell this particular human is a child of the other two humans? No, if we cannot make a genetic test. This GPT essay checker is a paternity test for written content.

Gptzero reviews.

GPTZero was the only consistent performer, classifying AI-generated text correctly. As for the rest … not so much.

GPTZero has been incomparably more accurate than any of the other AI checkers. For me, it’s the best solution to build trust with my clients.

This tool is a magnifying glass to help teachers get a closer look behind the scenes of a document, ultimately creating a better exchange of ideas that can help kids learn.

The granular detail provided by GPTZero allows administrators to observe AI usage across the institution. This data is helping guide us on what type of education, parameters, and policies need to be in place to promote an innovative and healthy use of AI.

After talking to the class, each student we compiled with GPTZero as possibly using AI ended up telling us they did, which made us extremely confident in GPTZero’s capabilities.

Sign up for GPTZero. Its feedback aligns well with my sense of what is going on in the writing - almost line-for-line.

I'm a huge fan of the writing reports that let me verify my documents are human-written. The writing video, in particular, is a great way to visualize the writing process!

Excellent chrome extension. I ran numerous tests on human written content and the results were 100% accurate.

Outstanding! This is an extraordinary tool to not only assess the end result but to view the real-time process it took to write the document.

GPTZero is the best AI detection tool for teachers and educators.

General FAQs about our AI Detector

Everything you need to know about GPTZero and our chat gpt detector. Can’t find an answer? You can talk to our customer service team .

What is GPTZero?

GPTZero is the leading AI detector for checking whether a document was written by a large language model such as ChatGPT. GPTZero detects AI on sentence, paragraph, and document level. Our model was trained on a large, diverse corpus of human-written and AI-generated text, with a focus on English prose. To date, GPTZero has served over 2.5 million users around the world, and works with over 100 organizations in education, hiring, publishing, legal, and more.

How do I use GPTZero?

Simply paste in the text you want to check, or upload your file, and we'll return an overall detection for your document, as well as sentence-by-sentence highlighting of sentences where we've detected AI. Unlike other detectors, we help you interpret the results with a description of the result, instead of just returning a number.

To get the power of our AI detector for larger texts, or a batch of files, sign up for a free account on our  Dashboard .

If you want to run the AI detector as your browse, you can download our  Chrome Extension, Origin , which allows you to scan the entire page in one click.

When should I use GPTZero?

Our users have seen the use of AI-generated text proliferate into education, certification, hiring and recruitment, social writing platforms, disinformation, and beyond. We've created GPTZero as a tool to highlight the possible use of AI in writing text. In particular, we focus on classifying AI use in prose.

Overall, our classifier is intended to be used to flag situations in which a conversation can be started (for example, between educators and students) to drive further inquiry and spread awareness of the risks of using AI in written work.

Does GPTZero only detect ChatGPT outputs?

No, GPTZero works robustly across a range of AI language models, including but not limited to ChatGPT, GPT-4, GPT-3, GPT-2, LLaMA, and AI services based on those models.

Why GPTZero over other detection models?

  • GPTZero is the most accurate AI detector across use-cases, verified by multiple independent sources, including TechCrunch, which called us the best and most reliable AI detector after testing seven others.
  • GPTZero builds and constantly improves our own technology. In our competitor analysis, we found that not only does GPTZero perform better, some competitor services are actually just forwarding the outputs of free, open-source models without additional training.
  • In contrast to many other models, GPTZero is finetuned for student writing and academic prose. By doing so, we've seen large improvements in accuracies for this use-case.

What are the limitations of the classifier?

The nature of AI-generated content is changing constantly. As such, these results should not be used to punish students. We recommend educators to use our behind-the-scene Writing Reports as part of a holistic assessment of student work. There always exist edge cases with both instances where AI is classified as human, and human is classified as AI. Instead, we recommend educators take approaches that give students the opportunity to demonstrate their understanding in a controlled environment and craft assignments that cannot be solved with AI .

The accuracy of our model increases as more text is submitted to the model. As such, the accuracy of the model on the document-level classification will be greater than the accuracy on the paragraph-level, which is greater than the accuracy on the sentence level.

The accuracy of our model also increases for text similar in nature to our dataset. While we train on a highly diverse set of human and AI-generated text, the majority of our dataset is in English prose, written by adults.

Our classifier is not trained to identify AI-generated text after it has been heavily modified after generation (although we estimate this is a minority of the uses for AI-generation at the moment).

Currently, our classifier can sometimes flag other machine-generated or highly procedural text as AI-generated, and as such, should be used on more descriptive portions of text.

What can I do as an educator to reduce the risk of AI misuse?

  • Help students understand the risks of using AI in their work (to learn more, see this article ), and value of learning to express themselves. For example, in real-life, real-time collaboration, pitching, and debate, how does your class improve their ability to communicate when AI is not available?
  • Ask students to write about personal experiences and how they relate to the text, or reflect on their learning experience in your class.
  • Ask students to critique the default answer given by Chat GPT to your question.
  • Require that students cite real, primary sources of information to back up their specific claims, or ask them to write about recent events.
  • Assess students based on a live discussion with their peers, and use peer assessment tools (such as the one provided by our partner, Peerceptiv ).
  • Ask students to complete their assignments in class or in an interactive way, and shift lectures to be take-home.
  • Ask students to produce multiple drafts of their work that they can revise as peers or through the educator, to help students understand that assignments are meant to teach a learning process.
  • Ask students to produce work in a medium that is difficult to generate, such as powerpoint presentations, visual displays, videos, or audio recordings.
  • Set expectations for your students that you will be checking the work through an AI detector like GPTZero, to deter misuse of AI.

I'm an educator who has found AI-generated text by my students. What do I do?

Firstly, at GPTZero, we don't believe that any AI detector is perfect. There always exist edge cases with both instances where AI is classified as human, and human is classified as AI. Nonetheless, we recommend that educators can do the following when they get a positive detection:

  • Ask students to demonstrate their understanding in a controlled environment, whether that is through an in-person assessment, or through an editor that can track their edit history (for instance, using our Writing Reports through Google Docs). Check out our list of several recommendations on types of assignments that are difficult to solve with AI.
  • Ask the student if they can produce artifacts of their writing process, whether it is drafts, revision histories, or brainstorming notes. For example, if the editor they used to write the text has an edit history (such as Google Docs), and it was typed out with several edits over a reasonable period of time, it is likely the student work is authentic. You can use GPTZero's Writing Reports to replay the student's writing process, and view signals that indicate the authenticity of the work.
  • See if there is a history of AI-generated text in the student's work. We recommend looking for a long-term pattern of AI use, as opposed to a single instance, in order to determine whether the student is using AI.

What data did you train your model on?

Our model is trained on millions of documents spanning various domains of writing including creating writing, scientific writing, blogs, news articles, and more. We test our models on a never-before-seen set of human and AI articles from a section of our large-scale dataset, in addition to a smaller set of challenging articles that are outside its training distribution.

How do I use and interpret the results from your API?

To see the full schema and try examples yourself, check out our  API documentation.

Our API returns a document_classification field which indicates the most likely classification of the document. The possible values are HUMAN_ONLY , MIXED , and AI_ONLY . We also provide a probability for each classification, which is returned in the class_probabilities field. The keys for this field are human , ai or mixed . To get the probability for the most likely classification, the predicted_class field can be used. The class probability corresponding to the predicted class can be interpreted as the chance that the detector is correct in its classification. I.e. 90% means that 90% of the time on similar documents our detector is correct in the prediction it makes. Lastly, each prediction comes with a confidence_category field, which can be high , medium , or low . Confidence categories are tuned such that when the confidence_category field is high 99.1% of human articles are classified as human, and 98.4% of AI articles are classified as AI.

Additionally, we highlight sentences that been detected to be written by AI. API users can access this highlighting through the highlight_sentence_for_ai field. The sentence-level classification should not be solely used to indicate that an essay contains AI (such as ChatGPT plagiarism). Rather, when a document gets a MIXED or AI_ONLY classification, the highlighted sentence will indicate where in the document we believe this occurred.

Are you storing data from API calls?

No. We do not store or collect the documents passed into any calls to our API. We wanted to be overly cautious on the side of storing data from any organizations using our API. However, we do store inputs from calls made from our dashboard. This data is only used in aggregate by GPTZero to further improve the service for our users. You can refer to our privacy policy for more details.

What is an AI Content Detector

AI text detector tool is a software that can recognize content generated by OpenAI Chat GPT through machine learning algorithms containing natural language processing techniques. It uses a huge dataset of human and AI-generated texts. This is one of the after-sought tools every student should implement for their academic purpose.

Leveraging ChatGPT in writing an essay saves you precious time. However, teachers and professors are also aware of AI content generators. They estimated the capabilities of such tech products and are very considerate of the essay’s originality. They also use an AI checker to identify whether a work is written by humans.

For this reason, an AI essay checker free tool is the best solution today to make your work slick and unique. Even if you craft an essay independently, an AI writer detector helps you to detect AI content that needs proofreading. So, you should deliver an original text when handing out your essay.

Accuracy Is Above All

Thanks to the high accuracy of our AI content checker, you can finalize your essay and improve its uniqueness.

Benefits to Check Text with AI Essay Detector

AI essay detector free is deployed along with plagiarism checkers today. These two instruments are crucial in crafting original and engaging content that will be highly valued. That’s why it is worth checking your text with this tool, as AI generates a myriad of information. You can’t even know whether you are reading an article written by a human or an AI.

Using a GPT content generator is not a crime. It brings some positive things to writers, like time-saving, correct grammar and spelling, and a solid content search to make your essay complete. But the uniqueness and data accuracy of such essays suffers as AI analyses much training data that can be outdated or presented in a complex way to comprehend. For this reason, AI content detectors are the best solution for improving the uniqueness of your content. 

Steps to Bypass AI Detection

We know how crucial it is for you to cope with your academic writing. We use our Chat GPT detector when dealing with students’ work, like any type of essay, research paper, coursework, dissertation, etc. If you are working on your essay individually, you can visit our website PapersOwl.com and check it with our detector for free. You will find all you need there and contact real experts to help you with any questions or concerns.

Here are a few steps we take to bypass AI essay detection:

  • Alternative paraphrasing. AI-generated text can be hard to read. So, it is better to change the phrases highlighted by the detector and add simple and understandable sentences.
  • Using synonyms. The phenomenon of tautology can be found in any text, including AI-written text. In this case, we offer to use proper synonyms where there are many repetitions of the same word form.
  • Including natural language. To add more creativity to your text, it is a good idea to use idioms, rhetorical questions, or colloquialisms. But don’t overuse them, and consider the type of essay you are writing.

We also offer editing and proofreading services. You can approach us to rewrite essay for you if you feel a lack of creativity or have no idea how to increase the uniqueness of your assignment.

This sentence was written by an AI—or was it? OpenAI’s new chatbot, ChatGPT, presents us with a problem: How will we know whether what we read online is written by a human or a machine?

Since it was released in late November, ChatGPT has been used by over a million people. It has the AI community enthralled, and it is clear the internet is increasingly being flooded with AI-generated text. People are using it to come up with jokes, write children’s stories, and craft better emails. 

ChatGPT is OpenAI’s spin-off of its large language model GPT-3 , which generates remarkably human-sounding answers to questions that it’s asked. The magic—and danger—of these large language models lies in the illusion of correctness. The sentences they produce look right—they use the right kinds of words in the correct order. But the AI doesn’t know what any of it means. These models work by predicting the most likely next word in a sentence. They haven’t a clue whether something is correct or false, and they confidently present information as true even when it is not. 

In an already polarized, politically fraught online world, these AI tools could further distort the information we consume. If they are rolled out into the real world in real products, the consequences could be devastating. 

We’re in desperate need of ways to differentiate between human- and AI-written text in order to counter potential misuses of the technology, says Irene Solaiman, policy director at AI startup Hugging Face, who used to be an AI researcher at OpenAI and studied AI output detection for the release of GPT-3’s predecessor GPT-2. 

New tools will also be crucial to enforcing bans on AI-generated text and code, like the one recently announced by Stack Overflow, a website where coders can ask for help. ChatGPT can confidently regurgitate answers to software problems, but it’s not foolproof. Getting code wrong can lead to buggy and broken software, which is expensive and potentially chaotic to fix. 

A spokesperson for Stack Overflow says that the company’s moderators are “examining thousands of submitted community member reports via a number of tools including heuristics and detection models” but would not go into more detail. 

In reality, it is incredibly difficult, and the ban is likely almost impossible to enforce.

Today’s detection tool kit

There are various ways researchers have tried to detect AI-generated text. One common method is to use software to analyze different features of the text—for example, how fluently it reads, how frequently certain words appear, or whether there are patterns in punctuation or sentence length. 

“If you have enough text, a really easy cue is the word ‘the’ occurs too many times,” says Daphne Ippolito, a senior research scientist at Google Brain, the company’s research unit for deep learning. 

Because large language models work by predicting the next word in a sentence, they are more likely to use common words like “the,” “it,” or “is” instead of wonky, rare words. This is exactly the kind of text that automated detector systems are good at picking up, Ippolito and a team of researchers at Google found in research they published in 2019.

But Ippolito’s study also showed something interesting: the human participants tended to think this kind of “clean” text looked better and contained fewer mistakes, and thus that it must have been written by a person. 

In reality, human-written text is riddled with typos and is incredibly variable, incorporating different styles and slang, while “language models very, very rarely make typos. They’re much better at generating perfect texts,” Ippolito says. 

“A typo in the text is actually a really good indicator that it was human written,” she adds. 

Large language models themselves can also be used to detect AI-generated text. One of the most successful ways to do this is to retrain the model on some texts written by humans, and others created by machines, so it learns to differentiate between the two, says Muhammad Abdul-Mageed, who is the Canada research chair in natural-language processing and machine learning at the University of British Columbia and has studied detection . 

Scott Aaronson, a computer scientist at the University of Texas on secondment as a researcher at OpenAI for a year, meanwhile, has been developing watermarks for longer pieces of text generated by models such as GPT-3—“an otherwise unnoticeable secret signal in its choices of words, which you can use to prove later that, yes, this came from GPT,” he writes in his blog. 

A spokesperson for OpenAI confirmed that the company is working on watermarks, and said its policies state that users should clearly indicate text generated by AI “in a way no one could reasonably miss or misunderstand.” 

But these technical fixes come with big caveats. Most of them don’t stand a chance against the latest generation of AI language models, as they are built on GPT-2 or other earlier models. Many of these detection tools work best when there is a lot of text available; they will be less efficient in some concrete use cases, like chatbots or email assistants, which rely on shorter conversations and provide less data to analyze. And using large language models for detection also requires powerful computers, and access to the AI model itself, which tech companies don’t allow, Abdul-Mageed says. 

The bigger and more powerful the model, the harder it is to build AI models to detect what text is written by a human and what isn’t, says Solaiman. 

“What’s so concerning now is that [ChatGPT has] really impressive outputs. Detection models just can’t keep up. You’re playing catch-up this whole time,” she says. 

Training the human eye

There is no silver bullet for detecting AI-written text, says Solaiman. “A detection model is not going to be your answer for detecting synthetic text in the same way that a safety filter is not going to be your answer for mitigating biases,” she says. 

To have a chance of solving the problem, we’ll need improved technical fixes and more transparency around when humans are interacting with an AI, and people will need to learn to spot the signs of AI-written sentences. 

“What would be really nice to have is a plug-in to Chrome or to whatever web browser you’re using that will let you know if any text on your web page is machine generated,” Ippolito says.

Some help is already out there. Researchers at Harvard and IBM developed a tool called Giant Language Model Test Room (GLTR), which supports humans by highlighting passages that might have been generated by a computer program. 

But AI is already fooling us. Researchers at Cornell University found that people found fake news articles generated by GPT-2 credible about 66% of the time. 

Another study found that untrained humans were able to correctly spot text generated by GPT-3 only at a level consistent with random chance.  

The good news is that people can be trained to be better at spotting AI-generated text, Ippolito says. She built a game to test how many sentences a computer can generate before a player catches on that it’s not human, and found that people got gradually better over time. 

“If you look at lots of generative texts and you try to figure out what doesn’t make sense about it, you can get better at this task,” she says. One way is to pick up on implausible statements, like the AI saying it takes 60 minutes to make a cup of coffee.

AI Content Detector FAQ

What is ai-generated text.

AI-generated content refers to text that is created by artificial intelligence platforms, using natural language processing techniques and machine learning algorithms. It is often produced by language models, such as chatbots or content generators, which have been trained on large datasets of human-generated text.

AI-generated content can be helpful in providing a foundation for further research and writing. Although AI-written copy is generally factually accurate, it does not express the natural originality of human thought, the nuances of human contextual understanding and judgment that reflects the unique nature of human communication and creativity. In some cases, factual errors, context misalignment and other challenges occur in AI content, in addition to the natural ethical challenges AI generated content poses. Quetext’s AI detector provides subscribers with the ability to better mitigate and manage these risks, helping assure originality of content.

What is an AI content detector?

To know how our AI content detector works, it helps to understand how AI content is created.

To create AI content, software must first be trained with a series of language models. The software is fed thousands of books, articles, and other written copy. The software consumes this content and learns the relationships between words and phrases, taking note of the statistical patterns of one word following the next, in addition to many other complex signals. Once a language model, like GPT, has been fully trained, it is able to read and understand questions posed to it, and respond with unique responses that are a combination of the thousands of articles it consumed during training.

Detecting AI content works in a similar manner. Generative AI content detectors analyze the content it is provided, looking for language nuances, statistical irregularities, and issues in authenticity and uniqueness. The tool then assigns a score based on how likely one word, phrase, etc. is to follow the next. Content that is considered ‘irregular’ is considered more unique, and thus, more likely to have been written by a human, than a chatbot or other AI tool.

The process of analyzing complex text to identify AI generated content is similar to the natural language processing analysis done to detect plagiarism , which is why Quetext’s AI detector outperforms other detectors.

How accurate are AI content detection tools?

Our AI Content Detector has been highly accurate in testing, consistently providing accurate AI writing detection. Artificial intelligence is a dynamic and rapidly developing field, with new technology emerging constantly, creating an ongoing challenge to continuously enhance solutions, develop new techniques and train platforms. Quetext’s unique position as the leading plagiarism checker and our leading-edge application of language processing technology provides a distinct advantage in developing and maintaining a leadership role in AI detection.

The accuracy of other AI content detection tools varies depending on the specific detection model and its training data. While these tools have improved over time, they can still have limitations, especially in detecting text generated by ChatGPT models like GPT-2, GPT-3, GPT-3.5, or GPT-4. False positives, where legitimate content is flagged as problematic, can and often occur.

Ongoing research aims to enhance the accuracy of these tools by refining algorithms, expanding training datasets, and addressing challenges associated with detecting AI-generated text. Quetext’s mission is to promote ethical writing practices through originality, including ensuring human-generated content, and we are committed to helping our society and subscribers employ best-in-class technology to achieve their goals and our mission.

Frequently Asked Questions

When a Language Model writes a sentence, it uses all its pre-training data to make a response based on statistics. This is significantly different from how humans write. To our AI writing detector, the presence of an AI text generator becomes clear when compared to a large collection of human writing.

We can detect the latest models of the following LLMs:

You can experience free AI detection on a trial basis by registering for a free Copyleaks account . 

We can recognize AI text patterns utilizing multiple techniques.

Since 2015, we’ve collected, ingested, and analyzed trillions of crawled and user-sourced content pages. Our data comes from thousands of universities and enterprises worldwide. We use that data to train our models to understand how humans write.

Also, utilizing AI technology, the AI detector can accurately recognize the presence of other AI-generated text. It knows how to identify and flag the signals it leaves behind. That attention to detail adds a layer of accuracy to the process.

Learn more about our  AI Detector testing methodologies .

Several significant differences exist between other AI detector tools and ours.

For example:

  • We use large-scale, credible data combined with machine learning and broad adoption to refine our understanding of text patterns. This results in over 99% accuracy—better than any other AI detector, and it’s improving daily.
  • As an enterprise platform, we offer seamless API and LMS integrations, allowing you to bring AI Detector directly into your system at scale.
  • The AI Detector is one of the most advanced platforms for reading and analyzing source code, including AI-generated code. It detects plagiarism even when code has been modified, such as altering variables or entire sections.
  • Our AI Detector doesn’t flag non-AI features of Grammarly, like spell check and grammar. In contrast, another AI detector incorrectly flagged 20% of Grammarly’s non-AI features as AI content—a significant 20% false positive rate. 
  • All Copyleaks products, including the AI Detector, are fully GDPR-compliant and SOC 2 and SOC 3-certified, ensuring the privacy and security of personal data audited by KPMG.

Our models need a certain volume of text to accurately determine the presence of AI. The higher the character count, the easier it is for our technology to determine irregular patterns, which results in a higher confidence rating for AI detection. 

The ideal text requirements for each of our AI offerings are as follows: 

AI Detector Browser Extension 

Minimum : 350 characters 

Maximum : 25,000 characters 

AI Detector Web-Based Platform

Minimum : 255 characters 

Maximum : 2,000 pages (There is no character maximum)

The likelihood of human-written content being mistakenly labeled as AI-generated is just 0.2%—the lowest among AI detectors.

We’re committed to fostering authenticity and digital trust by creating secure environments for idea-sharing and confident learning. Ensuring complete accuracy, especially in avoiding false accusations, is vital to this mission.

To address this, we’ve taken several precautions:

  • Our algorithms are designed to recognize human-generated text. Focusing on AI detection alone tends to lower accuracy and increase false positives.
  • We’ve implemented a feedback loop where users can rate result accuracy. This helps us learn from rare false positives and continuously improve our models.
  • We only introduce new model detection after thorough testing. We use beta testers for added assurance once internal testing meets a high confidence threshold.

Yes. In July 2023, four researchers worldwide published a study on the Cornell Tech-owned arXiv. The study declared Copyleaks AI Detector the most accurate for checking and detecting large language models (LLM) generated text. 

Since then, additional independent third-party studies have been released. Each one has highlighted the AI detector’s accuracy and efficiency. Read more about these third-party studies .

Only certain features of writing assistants can cause your content to be flagged by the AI Detector.

For example, Grammarly has a genAI-driven feature that rewrites your content to help improve it, shorten it, etc. As a result, this reworked content could get flagged as AI since it was rewritten by genAI. 

However, the Copyleaks Writing Assistant does not get flagged as AI. It won’t flag content that Grammarly changed to fix grammatical errors, mechanical issues, etc. This is because it does not use (or uses minimal) genAI to power these features.

At Copyleaks, our products routinely verify privacy, security, and compliance control independently. We aim to achieve certifications against global standards. We believe this is the clearest way to earn and retain the trust of the millions of Copyleaks users worldwide. 

Our current Copyleaks certifications and compliance standards include: 

  • SOC2 & SOC3
  • PCI Payment Card Industry Data Security Standard
  • NIST Risk Management Framework (RMF)

A college student created an app that can tell whether AI wrote an essay

GPTZero in action: The bot correctly detected AI-written text. The writing sample that was submitted? ChatGPT's attempt at "an essay on the ethics of AI plagiarism that could pass a ChatGPT detector tool."

Teachers worried about students turning in essays written by a popular artificial intelligence chatbot now have a new tool of their own.

Edward Tian, a 22-year-old senior at Princeton University, has built an app to detect whether text is written by ChatGPT, the viral chatbot that's sparked fears over its potential for unethical uses in academia.

Edward Tian, a 22-year-old computer science student at Princeton, created an app that detects essays written by the impressive AI-powered language model known as ChatGPT.

Tian, a computer science major who is minoring in journalism, spent part of his winter break creating GPTZero, which he said can "quickly and efficiently" decipher whether a human or ChatGPT authored an essay.

His motivation to create the bot was to fight what he sees as an increase in AI plagiarism. Since the release of ChatGPT in late November, there have been reports of students using the breakthrough language model to pass off AI-written assignments as their own.

"there's so much chatgpt hype going around. is this and that written by AI? we as humans deserve to know!" Tian wrote in a tweet introducing GPTZero.

Tian said many teachers have reached out to him after he released his bot online on Jan. 2, telling him about the positive results they've seen from testing it.

More than 30,000 people had tried out GPTZero within a week of its launch. It was so popular that the app crashed. Streamlit, the free platform that hosts GPTZero, has since stepped in to support Tian with more memory and resources to handle the web traffic.

How GPTZero works

To determine whether an excerpt is written by a bot, GPTZero uses two indicators: "perplexity" and "burstiness." Perplexity measures the complexity of text; if GPTZero is perplexed by the text, then it has a high complexity and it's more likely to be human-written. However, if the text is more familiar to the bot — because it's been trained on such data — then it will have low complexity and therefore is more likely to be AI-generated.

Separately, burstiness compares the variations of sentences. Humans tend to write with greater burstiness, for example, with some longer or complex sentences alongside shorter ones. AI sentences tend to be more uniform.

In a demonstration video, Tian compared the app's analysis of a story in The New Yorker and a LinkedIn post written by ChatGPT. It successfully distinguished writing by a human versus AI.

A new AI chatbot might do your homework for you. But it's still not an A+ student

Tian acknowledged that his bot isn't foolproof, as some users have reported when putting it to the test. He said he's still working to improve the model's accuracy.

But by designing an app that sheds some light on what separates human from AI, the tool helps work toward a core mission for Tian: bringing transparency to AI.

"For so long, AI has been a black box where we really don't know what's going on inside," he said. "And with GPTZero, I wanted to start pushing back and fighting against that."

The quest to curb AI plagiarism

AI-generated fake faces have become a hallmark of online influence operations

Untangling Disinformation

Ai-generated fake faces have become a hallmark of online influence operations.

The college senior isn't alone in the race to rein in AI plagiarism and forgery. OpenAI, the developer of ChatGPT, has signaled a commitment to preventing AI plagiarism and other nefarious applications. Last month, Scott Aaronson, a researcher currently focusing on AI safety at OpenAI, revealed that the company has been working on a way to "watermark" GPT-generated text with an "unnoticeable secret signal" to identify its source.

The open-source AI community Hugging Face has put out a tool to detect whether text was created by GPT-2, an earlier version of the AI model used to make ChatGPT. A philosophy professor in South Carolina who happened to know about the tool said he used it to catch a student submitting AI-written work.

The New York City education department said on Thursday that it's blocking access to ChatGPT on school networks and devices over concerns about its "negative impacts on student learning, and concerns regarding the safety and accuracy of content."

Tian is not opposed to the use of AI tools like ChatGPT.

GPTZero is "not meant to be a tool to stop these technologies from being used," he said. "But with any new technologies, we need to be able to adopt it responsibly and we need to have safeguards."

New Tool Can Tell If Something Is AI-Written With 99% Accuracy

  • Share to Facebook
  • Share to Twitter
  • Share to Linkedin

A new study found an AI detector developed by the University of Kansas can detect AI-generated content in academic papers with a 99% accuracy rate, one of the only detectors on the market specifically geared toward academic writing.

Genuine human error? Perhaps, but at least not artificial intelligence.

According to a report published Wednesday in the journal Cell Reports Physical Science, researchers created a tool that can prove AI detection in academic papers with 99% accuracy.

The team of researchers selected 64 perspectives (a type of article) and used them to make 128 articles using ChatGPT, which was then used to train the AI detector.

The model had a 100% accuracy rate of identifying human-created articles from AI-generated ones, and a 92% accuracy rate for identifying specific paragraphs within the text.

According to a survey by BestColleges.com, 89% of college students have admitted to using ChatGPT to help with assignments, while 34% of educators believe the software should be banned, though 66% support students having access.

Crucial Quote

“Right now, there are some pretty glaring problems with AI writing," lead author Heather Desaire said in a statement. "One of the biggest problems is that it assembles text from many sources and there isn't any kind of accuracy check—it's kind of like the game Two Truths and a Lie."

AI detectors have not proven to be 100% accurate. A University of California at Davis student alleges she was falsely accused by her university of cheating with AI. After uploading a paper for one of her classes, she received an email from her professor claiming a portion was flagged in the program Turnitin as being AI-generated. Her case was immediately forwarded to the Office of Student Support and Judicial Affairs, which handles discipline for academic misconduct. The student pleaded her case and ultimately won, using time stamps to prove she wrote the paper. This wasn’t the only time educators falsely labeled assignments as AI-generated. A Texas A&M commerce professor attempted to flunk over half of his senior class after using ChatGPT to test whether the students used the chatbot to write their papers. He copied and pasted the papers into ChatGPT and asked if it wrote them, to which it replied yes. This caused their diplomas to be withheld by the university, though the professor offered the opportunity to redo the assignment. However, the university confirmed to Insider no students were failed or barred from graduating.

Key Background

OpenAI’s chatbot, ChatGPT, was opened to the public in November 2022, and in less than a week surpassed the million-users mark, with people using it for things like creating code and writing essays. The AI’s intelligence led to several schools either indefinitely or temporarily banning the software, including New York Public Schools, Seattle Public Schools and the Los Angeles Unified School District.

There are already many existing programs and services that promise to identify AI-written content.

  • TurnitIn released an AI detection tool for papers. Before, it only had the capability to check for plagiarism. The feature has been added to its similarity report and shows an overall percentage of the amount of work AI software generated within the paper. The company claims its AI detection tool is 98% accurate at spotting AI-written work. Its detection model is trained to detect content from GPT-3 and GPT-3.5 language models, including ChatGPT. However, it claims that because GPT-4’s writing characteristics are similar to earlier models, it can detect content from this version “most of the time.”
  • Copyleaks claims to have an AI detection accuracy rate of 99%. Its software can detect AI-generated text across several models, including GPT-4 and earlier versions, and content created with Jasper AI. It also says it can detect AI content in multiple languages, including Spanish, Russian, French, Dutch and German.
  • Winston AI launched in February, and claims it performs this task with 99% accuracy. It only supports detection in English and French, though the company is looking to expand this soon to Spanish and German. It can detect content made using ChatGPT, Bard, Bing Chat, GPT-4 and other text generation tools.
  • OpenAI’s Classifier launched in January to distinguish between AI-written and human-written text. Though these are the same makers behind ChatGPT, the tool isn’t very accurate. It has a success rate of around 26% and incorrectly labels human work as AI work 9% of the time. However, OpenAI claims the accuracy increases as the length of the text increases as well. It’s “very unreliable” on texts with 1,000 characters or less, and OpenAI only recommends using the software on documents written in English. The company also warns against using Classifier as the primary decision making tool and suggests using it to complement other methods of detection.
  • AI Writing Check was developed by Quill and CommonLit to help teachers check for AI-created work in assignments. Its developers predict its accuracy is between 80% and 90%. It only allows detection for text up to 400 words at a time and for anything longer, users must break it down into sections. The detection software was created by OpenAI and is able to identify language syntactical patterns within text that aren’t quite humanlike.

Research corner

Check out the links below if you’re interested in the additional research we performed against English Language Learners and what an independent research study has revealed about Turnitin's AI-writing detection capabilities.

Research shows our AI scanner shows no statistically significant bias against English Language Learners

  • In response to customer feedback and papers claiming that AI detector tools are biased against writers whose first language is not English, we expanded our false positive evaluation to include writing samples of English Language Learners (ELL). We tested another nearly 2,000 writing samples of ELL writers.
  • We found that in documents meeting the 300-word count requirement, ELL writers received a 0.014 false positive rate, and native English writers received a 0.013.
  • This means that there is no statistically significant bias against non-native English speakers.

Independent research shows the “Turnitin [AI writing detector] achieved very high accuracy”

  • Two of the 16 detectors, Turnitin and Copyleaks, correctly identified the AI- or human-generated status of all 126 documents, with no incorrect or uncertain responses.
  • Three AI text detectors — Turnitin, Originality, and Copyleaks — have very high accuracy with all three sets of documents examined for this study: GPT-3.5 papers, GPT-4 papers, and human-generated papers.
  • Of the top three detectors identified in this investigation, Turnitin “achieved very high accuracy” in all five previous evaluations. Copyleaks, included in four earlier analyses, performed well in three of them.

The Future of SSDs: What Comes After NVME?

How new cars are slowing you down, these formerly paywalled ai tools are now available for free users, quick links, how to tell if chatgpt wrote that article, can you use ai to detect ai-generated text, tools to check if an article was written by chatgpt, train your brain to catch ai, key takeaways.

You can tell a ChatGPT-written article by its simple, repetitive structure and its tendency to make logical and factual errors. Some tools are available for automatically detecting AI-generated text, but they are prone to false positives.

AI technology is changing what we see online and how we interact with the world. From a Midjourney photo of the Pope in a puffer coat to language learning models like ChatGPT, artificial intelligence is working its way into our lives.

The more sinister uses of AI tech, like a political disinformation campaign blasting out fake articles, mean we need to educate ourselves enough to spot the fakes. So how can you tell if an article is actually AI generated text?

Multiple methods and tools currently exist to help determine whether the article you're reading was written by a robot. Not all of them are 100% reliable, and they can deliver false positives, but they do offer a starting point.

One big marker of human-written text, at least for now, is randomness. While people will write using different styles and slang and often make typos, AI language models very rarely make those kinds of mistakes. According to MIT Technology Review , "human-written text is riddled with typos and is incredibly variable," while AI generated text models like ChatGPT are much better at creating typo-less text. Of course, a good copy editor will have the same effect, so you have to watch for more than just correct spelling.

Another indicator is punctuation patterns. Humans will use punctuation more randomly than an AI model might. AI generated text also usually contains more connector words like "the," "it," or "is" instead of larger more rarely used words because large language models operate by predicting what word will is most likely to come next, not coming up with something that would sound good the way a human might.

This is visible in ChatGPT's response to one of the stock questions on OpenAI's website. When asked, "Can you explain quantum computing in simple terms," you get sentences like: "What makes qubits special is that they can exist in multiple states at the same time, thanks to a property called superposition. It's like a qubit can be both a 0 and a 1 simultaneously. "

Chat GPT answering the question "Can you explain quantum computing in simple terms?"

Short, simple connecting words are regularly used, the sentences are all a similar length, and paragraphs all follow a similar structure. The end result is writing that sounds and feels a bit robotic.

Large language models themselves can be trained to spot AI generated writing. Training the system on two sets of text --- one written by AI and the other written by people --- can theoretically teach the model to recognize and detect AI writing like ChatGPT.

Researchers are also working on watermarking methods to detect AI articles and text. Tom Goldstein, who teaches computer science at the University of Maryland, is working on a way to build watermarks into AI language models in the hope that it can help detect machine-generated writing even if it's good enough to mimic human randomness.

Invisible to the naked eye, the watermark would be detectable by an algorithm, which would indicate it as either human or AI generated depending on how often it adhered to or broke the watermarking rules. Unfortunately, this method hasn't tested so well on later models of ChatGPT.

You can find multiple copy-and-paste tools online to help you check whether an article is AI generated. Many of them use language models to scan the text, including ChatGPT-4 itself.

Undetectable AI , for example, markets itself as a tool to make your AI writing indistinguishable from a human's. Copy and paste the text into its window and the program checks it against results from other AI detection tools like GPTZero to assign it a likelihood score --- it basically checks whether eight other AI detectors would think your text was written by a robot.

Originality is another tool, geared toward large publishers and content producers. It claims to be more accurate than others on the market and uses ChatGPT-4 to help detect text written by AI. Other popular checking tools include:

Most of these tools give you a percentage value, like 96% human and 4% AI, to determine how likely it is that the text was written by a human. If the score is 40-50% AI or higher, it's likely the piece was AI-generated.

While developers are working to make these tools better at detecting AI generated text, none of them are totally accurate and can falsely flag human content as AI generated. There's also concern that since large language models like GPT-4 are improving so quickly, detection models are constantly playing catchup.

In addition to using tools, you can train yourself to catch AI generated content. It takes practice, but over time you can get better at it.

Daphne Ippolito, a senior research scientist at Google's AI division Google Brain, made a game called Real Or Fake Text  (ROFT) that can help you separate human sentences from robotic ones by gradually training you to notice when a sentence doesn't quite look right.

One common marker of AI text, according to Ippolito, is nonsensical statements like "it takes two hours to make a cup of coffee." Ippolito's game is largely focused on helping people detect those kinds of errors. In fact, there have been multiple instances of an AI writing program stating inaccurate facts with total confidence --- you probably shouldn't ask it to do your math assignment , either, as it doesn't seem to handle numerical calculations very well.

Right now, these are the best detection methods we have to catch text written by an AI program. Language models are getting better at a speed that renders current detection methods outdated pretty quickly, however, leaving us in, as Melissa Heikkilä writes for MIT Technology Review, an arms race.

Student Creates App to Detect Essays Written by AI

In response to the text-generating bot ChatGPT, the new tool measures sentence complexity and variation to predict whether an author was human

Margaret Osborne

Daily Correspondent

In November, artificial intelligence company OpenAI released a powerful new bot called ChatGPT, a free tool that can generate text about a variety of topics based on a user’s prompts. The AI quickly captivated users across the internet, who asked it to write anything from song lyrics in the style of a particular artist to programming code.

But the technology has also sparked concerns of AI plagiarism among teachers, who have seen students use the app to write their assignments and claim the work as their own. Some professors have shifted their curricula because of ChatGPT, replacing take-home essays with in-class assignments, handwritten papers or oral exams, reports Kalley Huang for the New York Times . 

“[ChatGPT] is very much coming up with original content,” Kendall Hartley , a professor of educational training at the University of Nevada, Las Vegas, tells Scripps News . “So, when I run it through the services that I use for plagiarism detection, it shows up as a zero.” 

Now, a student at Princeton University has created a new tool to combat this form of plagiarism: an app that aims to determine whether text was written by a human or AI. Twenty-two-year-old Edward Tian developed the app, called GPTZero , while on winter break and unveiled it on January 2. Within the first week of its launch, more than 30,000 people used the tool, per NPR ’s Emma Bowman. On Twitter, it has garnered more than 7 million views. 

GPTZero uses two variables to determine whether the author of a particular text is human: perplexity, or how complex the writing is, and burstiness, or how variable it is. Text that’s more complex with varied sentence length tends to be human-written, while prose that is more uniform and familiar to GPTZero tends to be written by AI.

But the app, while almost always accurate, isn’t foolproof. Tian tested it out using BBC articles and text generated by AI when prompted with the same headline. He tells BBC News ’ Nadine Yousif that the app determined the difference with a less than 2 percent false positive rate.

“This is at the same time a very useful tool for professors, and on the other hand a very dangerous tool—trusting it too much would lead to exacerbation of the false flags,” writes one GPTZero user, per the Guardian ’s Caitlin Cassidy. 

Tian is now working on improving the tool’s accuracy, per NPR. And he’s not alone in his quest to detect plagiarism. OpenAI is also working on ways that ChatGPT’s text can easily be identified. 

“We don’t want ChatGPT to be used for misleading purposes in schools or anywhere else,” a spokesperson for the company tells the Washington Post ’s Susan Svrluga in an email, “We’re already developing mitigations to help anyone identify text generated by that system.” One such idea is a watermark , or an unnoticeable signal that accompanies text written by a bot.

Tian says he’s not against artificial intelligence, and he’s even excited about its capabilities, per BBC News. But he wants more transparency surrounding when the technology is used. 

“A lot of people are like … ‘You’re trying to shut down a good thing we’ve got going here!’” he tells the Post . “That’s not the case. I am not opposed to students using AI where it makes sense. … It’s just we have to adopt this technology responsibly.”

How To Tell if AI Wrote an Essay: 5 Effective Methods

how to tell if ai wrote an essay

At the 2016 Rio Olympics, The Washington Post made the choice to use automated storytelling for their coverage of the event.

They created an exclusive digital platform filled with AI content creation tools needed by today’s publishers.

Because of their platform, the writers could produce more than 850 stories. This puts them above the rest when it comes to providing coverage, making them a top choice for readers.

This is how AI-generated content is done right. Having timely narratives alongside traditional reporting is a smart use of technology.

That being said, like most great things, AI can also be abused.

As a professional educator, researcher, or just a curious reader, it’s important to know how to tell if AI wrote an essay.

Because of how advanced AI content creation has gotten, it may not be easy to tell which is human and AI-generated at first glance.

Here’s everything you need to know about AI-content detection.

5 Strategies for Identifying AI-Written Essays

AI has come a long way, going way back to the 1950s by Alan Turing. The Turing Test was used to measure a machine’s ability to display human-like intelligence.

artificial intelligence timeline

Basically, if a machine can engage with a human without being detected as a machine, it passes the test.

Decades later, AI is now used for content creation.

This is all thanks to how technology has evolved with natural language processing (NLP) and other machine learning algorithms that can analyze huge amounts of data and create human-like responses.

AI is now widely used, especially in academic contexts. Without responsible AI use, the authenticity and transparency that institutions protect are tarnished.

Even in college admissions , knowing how to tell if an essay is AI-generated is becoming a priority.

Colleges and universities are taking proactive measures to prevent AI from influencing admission decisions.

They are now investing in tools and planning multiple strategies to prevent the submission of AI-written material.

To help you out with this challenge, here are five effective strategies to identify AI-written content.

1. Using AI Content Detection Tools

Consider a teacher receiving a big batch of electronically submitted student essays.

As she reviews them, she notices one that gives off a very unusual writing style. With the workload she’s handling, checking manually can be a hassle.

Thanks to AI content detection tools, she can easily submit the text and check.

This lets her identify essays that might require a closer look, ensuring the academic integrity and fairness of grading stays intact.

Remember that we now live in a time where AI plagiarism actually exists.

For instance, a highly-rated AI content detector like Undetectable AI can detect AI content with unparalleled accuracy.

undetectable ai detector and humanizer homepage

It can quickly find inconsistencies, deviations, and unnatural language within seconds – all wrapped in an easy-to-use interface.

Here are some ways that AI detectors like Undetectable AI are commonly used.

  • Educational institutions and academic platforms can use AI content detection tools to screen assignments submitted by students.
  • Publishers, media outlets, and content creators use AI content detection to evaluate how authentic their written content is before reaching publication.
  • Researchers and scholars rely on AI content detection tools to prevent the spread of misinformation or inaccurate findings.
  • Beyond just identifying AI-written essays, AI content detection includes comparing a vast database of content to make sure that the written text is not plagiarized.
  • Content producers and marketers take advantage of AI tools to preserve brand reputation by checking that the writing style and tone are not inconsistent.
  • AI content detection tools assist in verifying the authenticity of written documents and maintaining compliance with intellectual property laws.

With the use of AI content detection tools, it will be much easier for institutions and organizations to adapt to the rise of AI use across various professions.

But when AI is used correctly, it can help automate processes, lessen routine work, and empower professionals to work harder on what makes an impact.

It’s a combo move that’s worth putting in the effort.

2. Analyzing Tone and Style

A simple yet effective hands-on way how to tell if an essay is AI-generated is by looking at how the written content sounds.

You can usually watch out for these red flags.

  • Real human-written essays usually show some sort of “natural variability.” This means that there is a tone that’s specific to the writer, making it uniquely theirs.
  • AI content generators have a really hard time incorporating human emotion into their content. These generators create content purely based on a prompt and usually feel very generic and, as cliché as it sounds, robotic.
  • There’s a lack of relatable experiences and fresh perspectives, basically looking like the text was paraphrased from an already existing article.
  • AI isn’t capable of going deeper into complex topics. There’s a huge lack of sophistication in the style of writing, being unable to provide clear analysis, interpretation, and insights.

By honing your observation skills, you, as a human reader, can instinctively detect these subtle nuances.

While automated tools can undoubtedly help with identifying AI-written essays, the power of human observation never goes away.

3. Identifying Lack of Personal Touch

When it comes to writing, the personal touch is the unique style that makes a written work uniquely the author’s.

It’s the individual’s voice and connection to the reader that makes essays feel real. This is why identifying a lack of personal touch is one of the best ways to know if something is AI-generated.

While AI tools like ChatGPT certainly have promise for the future of academic research, writers and researchers need to acknowledge the current limitations must be approached with caution.

chatgpt for assitant in college aplications

As H. Holden Thorp , Editor-in-Chief of the Science family of journals, points out, “ChatGPT is fun, but not an author.”

While AI content tools can be useful tools for inspiration and idea generation, we need to think ethically and make sure that the content we produce stays accurate and reliable.

4. Spotting Repetitive Language

One of the biggest telltale signs of AI-generated content is repetitive language. AI algorithms rely heavily on established patterns and templates to produce text.

As a result, AI-generated content usually shows a lot of repetitions, which shows how limited the algorithm’s programming is.

From the get-go, you will notice how monotonous the text is. This is because the repetitive texts and phrases used are also generic.

AI has a limited vocabulary when generating texts, which really stand out when you read them.

While repeating words doesn’t automatically mean something’s AI content, it’s a supplementary action that you can take note of to know if written content feels off.

5. Assessing Accuracy and Relevance

If you instruct an AI content generator to provide a statistic on the number of people who wake up from their sleep and walk down the stairs to drink a glass of milk, it is most likely to do so.

But what it doesn’t do is verify whether the information it just provided is correct or if it even exists.

What data AI provides is only the data in its database. This means that the information can be outdated.

There can also be inconsistencies and even bias, depending on where the data comes from.

It’s scary to think that AI-generated content can be alarmingly convincing.

People are 3% less likely to spot inaccurate information when content is AI-written because AI makes content condensed and easy to process.

This is why it’s important to be cautious about how you use information online.

Importance of Distinguishing Human and AI-Crafted Essays

In a nutshell, it’s important to recognize the differences between human and AI content to maintain authenticity, prevent misinformation, and avoid plagiarism.

Here’s a rundown of why you should distinguish human from AI work.

  • Preventing plagiarism and ensuring that students receive recognition for their original work.
  • Preserving the credibility of published works, research findings, and journalistic pieces.
  • Fighting the spread of fake news online.
  • Clarifying the origin of essays supports ethical practices in writing and publishing.

Take note that this does not mean that we should outright ban the use of AI.

We should encourage responsible innovation in the field, and find the balance between using AI technology for efficiency and still being able to maintain the unique value of human creativity and expression.

How to Tell If What You're Reading Was Written By AI

An illustration of a typewriter with a piece of paper covered in digital text of the alphabet with some letters transposed

This post is part of Lifehacker’s “Exposing AI” series. We're exploring six different types of AI-generated media, and highlighting the common quirks, byproducts, and hallmarks that help you tell the difference between artificial and human-created content.

From the moment ChatGPT introduced the world to generative AI in late 2022 , it was apparent that, going forward, you can no longer trust that something you're reading was written by a human. You can ask an AI program like ChatGPT to write something—anything at all—and it will, in mere seconds. So how can you trust that what you're reading came from the mind of a person, and not the product of an algorithm?

If the ongoing deflation of the AI bubble has shown us anything, it's that most people kind of hate AI in general , which means they probably aren't keen on the idea that what they are reading was thoughtlessly spit out by a machine. Still, some have fully embraced AI's ability to generate realistic text, for better or, often, worse. Last year, CNET quietly began publishing AI content alongside human-written articles , only to face scorn and backlash from its own employees. Former Lifehacker parent company G/O Media also published AI content on its sites , albeit openly, and experienced the same blowback—both for implementing the tech with zero employee input, and because the content itself was just terrible .

But not all AI-generated text announces itself quite so plainly. When used correctly, AI programs can generate text that is convincing—even if you can still spot clues that reveal its inhuman source.

How AI writing works

Generative AI isn't some all-knowing digital consciousness that can answer your questions like a human would. It's not actually "intelligent" at all. Current AI tools are powered by large language models (LLMs), which are deep-learning algorithms trained on huge data sets—in this case, data sets of text. This training informs all of their responses to user queries. When you ask ChatGPT to write you something, the AI breaks down your question and identifies what it "thinks" are the most important elements in your query. It then "predicts" what the right sequence of words would be to answer your request, based on its understanding of the relationship between words.

More powerful models are able to both take in more information at once, as well as return longer, more natural results in kind. Plus, it's common for chatbots to be programmed with custom instructions that apply to all prompts, which, if used strategically, can potentially mask the usual signs of AI-generated text.

That said, no matter how you coax the AI into responding, it is beholden to its training, and there will likely be signs such a piece of text was generated by an LLM. Here are some things to look out for.

Watch for commonly used words and phrases

Because chatbots have been trained to look for the relationships between words, they tend to use certain words and phrases more often than a person would. There's no specific list of words and phrases that serve as red flags, but if you use a tool like ChatGPT enough, you may start to pick up on them.

For example, ChatGPT frequently uses the word "delve," especially during transitions in writing. (e.g. "Let's delve into its meaning.") The tool also loves to express how an idea "underscores" the overall argument (e.g. "This experience underscores the importance of perseverance..."), and how one thing is "a testament to" something else. (I generated three essays with ChatGPT for this section—two with GPT-4o and one with GPT-4o mini —and "testament" popped up in each one.)

Similarly, you may see repeated uses of words like "emerge," "relentless," "groundbreaking," among other notable regulars. In particular, when ChatGPT is describing a collection of something, it will often call it a "mosaic" or a "tapestry." (e.g. "Madrid’s cultural landscape is a vibrant mosaic .")

This Reddit thread from r/chatgpt highlights a bunch of these commonly generated—though it's worth noting that the post is 10 months old, and OpenAI frequently updates its models, so some of it may not be as relevant today. In my testing, I found some of the Reddit thread's most-cited words didn't appear in my test essays at all, while others certainly did, with frequency.

All these words are certainly perfectly fine to use when doing your own writing. If a student writes "delve into" in their essay, that isn't a smoking gun that proves they generated it with ChatGPT. If an employee writes that something is "a testament to" something else in a report, that doesn't mean they're outsourcing their work to AI. This is just one aspect of AI writing to note as you analyze text going forward.

Consider the style of the writing

It's impressive how quickly AI can generate a response to a query, especially when you're working with a particularly powerful LLM. And while some of that writing can appear very natural, if you're reading closely, you'll start to notice quirks that most human writers wouldn't use.

Whether you're using OpenAI's GPT model or Google's Gemini, AI has a bad habit of using flowery language in its generations, as if it was mostly trained on marketing copy. AI will often try to sell you hard on whatever it happens to be talking about: The city it's writing about is often "integral," "vibrant," and a "cornerstone" of the country it's in; the analogy it uses "beautifully" highlights the overall argument; a negative consequence is not just bad, but "devastating." None of these examples is damning in isolation, but if you read enough AI text, you'll start to feel like you've been talking to a thesaurus.

This becomes even more apparent when a chatbot is attempting to use a casual tone. If the bot is purporting to be a real person, for example, it often will present as bubbly and over-the-top, and far too enthusiastic to listen to anything you have to say. To be fair, in my testing for this article, ChatGPT's GPT-4o model didn't appear to do this as much as it used to, preferring more succinct responses to personal queries—but Meta AI's chatbot absolutely still does it, stepping into the roles of both best friend and therapist whenever I shared a fake problem I was having.

If you're reading an essay or article that expresses an argument, take note of how the "writer" structures their points. Someone who asks an AI tool to write an essay on a subject without giving it too much coaching will often receive an essay that doesn't actually delve into the arguments all that much. The AI will likely generate short paragraphs offering surface-level points that don't add much to deepen the argument or contribute to the narrative, masking these limitations with the aforementioned $10 words and flowery language. Each paragraph might come across more of a summary of the argument, rather than an attempt to contribute to the argument itself. Remember, an LLM doesn't even know what it's arguing; it just strings together words it believes belong together.

If you feel you've walked away from the piece having learned nothing at all, that might be AI's doing.

Fact check and proofread

LLMs are black boxes. Their training is so intricate, we can't peer inside to see exactly how they established their understanding of the relationships between words. What we do know is, all AI has the capability (and the tendency) to hallucinate . In other words, sometimes it an AI will just make things up. Again, LLMs don't actually know anything: They just predict patterns of words based on their training. So while a lot of what they spit out will likely be rooted in the truth, sometimes it predicts incorrectly, and you might get some bizarre results on the other end. If you're reading a piece of text, and you see a claim you know isn't true stated as fact, especially without a source, be skeptical.

On the flip side, consider how much proofreading the piece required. If there were zero typos and no grammatical mistakes, that's also an AI tell: These models might make things up, but they don't output mistakes like misspellings. Sure, maybe the author made sure to dot every "i" and cross every "t," but if you're already concerned the text was generated with AI, stilted perfectionism can be a giveaway.

Try an AI text detector (but you can't trust those either)

AI detectors, like LLMs, are based on AI models. However, instead of being trained on large volumes of general text, these detectors are trained specifically on AI text. In theory, this means they should be able to spot AI text when presented with a sample. That's not always the case.

When I wrote about AI detectors last year , I warned not to use them, because they were not as reliable as they claimed to be. It's tough to say how much they have improved in the time since: When I feed one of my stories through a tool like ZeroGPT , it says my piece was 100% human-written. (Damn right.) If I submit an essay generated by Gemini about the significance of Harry losing his parents in the Harry Potter series, the tool identifies 94.95% of the piece as AI-generated. (The only sentence it thinks was written by a human was: "This personal stake in the conflict distinguishes Harry from other characters, granting him an unwavering purpose." Sure.)

And yet the detector still fails the same test I gave it in 2023: It believes 100% of Article 1., Section 2. of the United States Constitution is AI-generated. Someone tell Congress! I also set it to analyzing this short article from The New York Times , published July 16, 2015, long before the advent of modern LLMs. Again, I was assured the piece was 100% AI.

There are a lot of AI detectors on the market, and maybe some are better than others. If you find one that tends to reliably identify text you know to be human-generated as such, and likewise for text you know is AI, go ahead and test writing you aren't sure about. But I still think the superior method is analyzing it yourself. AI text is getting more realistic, but it still comes with plenty of tells that give itself away—and often, you'll know it when you see it.

A Princeton student built an app which can detect if ChatGPT wrote an essay to combat AI-based plagiarism

  • A Princeton student built an app that aims to tell if essays were written by AIs like ChatGPT.
  • The app analyzes text to see how randomly it is written, allowing it to detect if it was written by AI.
  • The website hosting the app, built by Edward Tian, crashed due to high traffic.

Insider Today

A new app can detect whether your essay was written by ChatGPT, as researchers look to combat AI plagiarism.

Edward Tian, a computer science student at Princeton, said he spent the holiday period building GPTZero.

He shared two videos comparing the app's analysis of a New Yorker article and a letter written by ChatGPT. It correctly identified that they were respectively written by a human and AI.

—Edward Tian (@edward_the6) January 3, 2023

GPTZero scores text on its "perplexity and burstiness" – referring to how complicated it is and how randomly it is written. 

The app was so popular that it crashed "due to unexpectedly high web traffic," and currently displays a beta-signup page . GPTZero is still available to use on Tian's Streamlit page, after the website hosts stepped in to increase its capacity.

Tian, a former data journalist with the BBC, said that he was motivated to build GPTZero after seeing increased instances of AI plagiarism.

"Are high school teachers going to want students using ChatGPT to write their history essays? Likely not," he tweeted.

The Guardian recently reported that ChatGPT is introducing its own system to combat plagiarism by making it easier to identify, and watermarking the bot's output.

That follows The New York Times' report that Google issued a "code red" alert over the AI's popularity.  

Insider's Beatrice Nolan also tested ChatGPT to write cover letters for job applications , with one hiring manager saying she'd have got an interview, though another said the letter lacked personality.

Tian added that he's planning to publish a paper with accuracy stats using student journalism articles as data, alongside Princeton's Natural Language Processing group. 

OpenAI and Tian didn't immediately respond to Insider's request for comment, sent outside US working hours.

Identifying   AI-Written   Essays:   A   Step-by-Step   Guide   for   Teachers

Theodosis Karageorgakis

Students have already started using ChatGPT to assist them in writing essays like maniacs. Instead of spending the effort required to practice their writing skills and come up with their own ideas, they rely on ChatGPT for AI-written Essays. Teachers have been trying to find ways to counter this practice without much success.

In our previous article, we discussed 5 ways that ChatGPT could assist you with your work. In this article, we will show you what you need to do to find out if a student has cheated using AI software.  

Steps for identifying AI-written Essays

Up until now, the software we had at our disposal, even the commercial ones, such as Turnitin, could only help us discover plagiarised content, not AI-written ones. So, what do we do to counter AI-written essays?

Step 1. Look for issues with the content

The first thing you need to look for is signs of unnatural language, such as repetitive sentence structures or overly complex vocabulary, which are common characteristics of text generated by machine learning models.

ChatGPT can’t fully understand the context or meaning of the text it generates and, therefore, often repeats phrases or uses words that may not be suitable for the particular context.

Step 2. Compare the Essay with the student's previous performance

Next, you need to compare the student’s writing style and use of language throughout the academic year with the essay they have submitted, and you suspect trickery. For example, suppose a student has demonstrated a certain language and writing style throughout the academic year and suddenly gives you a significantly more advanced essay or an essay written in a completely different style from their usual one. In that case, this could be a sign that the student has cheated.

Still, this method can be subjective and prone to mistakes. So, what should you do next to confirm if there was cheating?

Step 3. Use an AI-detection software

Now, you have to fight back, using the same weapons as the potential perpetrator. These weapons are the AI-detection software and can increase the likelihood of identifying cheating.

Option 1: AI Content Detector

Let’s begin with our first choice, called AI Content Detector.  To use it:

  • First, go to https://writer.com/ai-content-detector/ .
  • Next, copy and paste the student’s essay within the “add some text” field.
  • Then we click “Analyze Text”.
  • After it’s done analysing, it will come up with a result labelled as AI detection score on the top right side of our screen. The AI Content Detector will point out how much AI-generated text was found within the essay.

Obviously, the AI Content Detector is not flawless . But it’s free and works OK, especially if the student hasn’t made any substantial edits to the generated Essay they received from ChatGPT. In any case, you can use AI Content Detector for free as long as the text you input is less than 1500 words. If you want more, you can always upgrade to a paid plan for 162$ per year.

Option 2: ZeroGPT

Our next choice is called ZeroGPT . ZeroGPT is free and was exclusively developed for identifying essays generated by ChatGPT .

ZeroGPT’s developers claim that it has a detection rate of around 98.5% .

Actually, I tested their claim. The results were incredible. ZeroGPT accurately identified all text written by ChatGPT’s AI during my test runs. It is even more potent than the AI Content Detector as it uses advanced algorithms to identify foul plays.

  • To use it, first, you have to visit https://www.zerogpt.com/ .
  • Next, you copy and paste the text within the empty field. There’s no restriction to the number of words you can input. 
  • Now you have to press the Detect Text button. ZeroGPT will analyse your input, and within a few seconds, it will come up with a result defining if the text was written either by ChatGPT or by a real person.

Bottom line

As the AI language models become more sophisticated, they make it increasingly hard to distinguish between human-written and AI-generated text. Thankfully, programmers have already started to come up with new software that can help teachers identify content that was not written by their students. Please note that the AI Content Detector and ZeroGPT aren’t the only choices available at the moment, but they are free and work well in most cases.

In conclusion, keeping an eye out for unnatural language and comparing a student’s writing style throughout the year, as well as using AI detection software, can help you identify AI-written content, at least on some level.
