💯 12 Online Plagiarism Checkers

🔗 references, 🤔 why use a plagiarism checker.

The issues of plagiarism and academic dishonesty become more and more relevant each year. According to some research , 92% of surveyed students stated that they had or knew someone who had cheated .

So, why does this happen?

The researchers have shed light on this phenomenon, and here are some of their statistics:

• 92% of those who plagiarized stated that they did so because they wanted better grades.
• 83% said that they cheated because of procrastination.
• 75% of respondents pointed out that they did not have enough time to finish their assignments.
• 33% have attempted to cheat due to their overloaded class schedule.
• 58% of the surveyed have plagiarized because they lacked an understanding of the subject.
• 50% had little or no interest in the subject.
• 25% of participants believe that anyone can cheat without any consequences.
• 17% of the interviewees cheated because of peer pressure.
• Another 17% think that it does not matter to the professor if their paper is plagiarized.

After taking all of these numbers into account, it is evident that a significant percentage of students commit acts of plagiarism for several main reasons. Among them are poor time management, concern for academic performance, and peer pressure.

Now that you know the causes of plagiarism, it will be beneficial to examine its different types. Generally, these can be divided into two groups: unintentional and intentional.

Intentional Plagiarism

When it comes to intentional plagiarism, it doesn’t necessarily mean that your paper copies the full document written by someone else. This is only one example of cheating out of many others.

Unintentional Plagiarism

Meanwhile, unintentional plagiarism may refer to:

• Forgetting to cite a source when describing something that is not common knowledge.
• Not citing information that you have paraphrased or summarized.
• Failing to use a proper citation style when documenting sources.
• Misquoting an author, even if it is appropriately cited in the paper.

When composing your paper, it is important to stay vigilant. This is why it is handy to utilize the help of our plagiarism checker (2000 words). Free detection software is a quick and easy way to confirm your paper’s originality.

🔍 How to Check for Plagiarism

As you work on your paper, you may start to ask yourself: How can I avoid plagiarism altogether?

Below, we have prepared some tips that will help you write a 100% original essay:

• Regulate your time. As mentioned earlier, procrastination and a full class schedule may lead to plagiarism. To stay on top of everything, don’t put off urgent tasks until tomorrow. Read up on time management techniques and figure out an efficient study method that works for you.
• Cite while you write. Get in the habit of citing sources in full as you write your paper. Firstly, doing this will save you plenty of time for putting together a bibliography. Second, it will significantly decrease the risk of an improper citation.
• Use only trusted sources. There are a lot of websites with questionable content. Even documents that seem scholarly at first could turn out to be another student’s paper. Ascertain that you understand the source and the ideas that it is trying to convey.
• Understand the difference between various citation styles. An improper citation may result in a penalty for plagiarism. So, make sure you rely on a high-quality reference guide and implement the correct style. Don’t forget to add quotation marks when using unchanged phrasing from the source.
• Use plagiarism scanners before you submit your paper. Even if you wrote your piece from scratch, we still advise you to double-check it. From time to time, you might unintentionally “borrow” a couple of phrases that appear in other works. Despite it being an accident, your professor might penalize your paper. To avoid this, you can use one of the online free plagiarism detectors.

Perhaps our free plagiarism checker (2000 words & more) wasn’t exactly what you were looking for. If you find yourself in need of a tool with slightly different features, this section is for you!

Check for unintentional plagiarism

Easily check your paper for missing citations and accidental plagiarism with the EasyBib plagiarism checker. The EasyBib plagiarism checker:

• Scans your paper against billions of sources.
• Identifies text that may be flagged for plagiarism.
• Provides you with a plagiarism score.

You can submit your paper at any hour of the day and quickly receive a plagiarism report.

What is the EasyBib plagiarism checker? 

Most basic plagiarism checkers review your work and calculate a percentage, meaning how much of your writing is indicative of original work. But, the EasyBib plagiarism checker goes way beyond a simple percentage. Any text that could be categorized as potential plagiarism is highlighted, allowing you time to review each warning and determine how to adjust it or how to cite it correctly.

You’ll even see the sources against which your writing is compared and the actual word for word breakdown. If you determine that a warning is unnecessary, you can waive the plagiarism check suggestion.

Plagiarism is unethical because it doesn’t credit those who created the original work; it violates intellectual property and serves to benefit the perpetrator. It is a severe enough academic offense, that many faculty members use their own plagiarism checking tool for their students’ work. With the EasyBib Plagiarism checker, you can stay one step ahead of your professors and catch citation mistakes and accidental plagiarism before you submit your work for grading.

Why use a plagiarism checker? 

Imagine – it’s finals week and the final research paper of the semester is due in two days. You, being quite familiar with this high-stakes situation, hit the books, and pull together a ten-page, last-minute masterpiece using articles and materials from dozens of different sources.

However, in those late, coffee-fueled hours, are you fully confident that you correctly cited all the different sources you used? Are you sure you didn’t accidentally forget any? Are you confident that your teacher’s plagiarism tool will give your paper a 0% plagiarism score?

That’s where the EasyBib plagiarism checker comes in to save the day. One quick check can help you address all the above questions and put your mind at ease.

What exactly is plagiarism? 

Plagiarism has a number of possible definitions; it involves more than just copying someone else’s work. Improper citing, patchworking, and paraphrasing could all lead to plagiarism in one of your college assignments. Below are some common examples of accidental plagiarism that commonly occur.

Quoting or paraphrasing without citations

Not including in-text citations is another common type of accidental plagiarism. Quoting is taking verbatim text from a source. Paraphrasing is when you’re using another source to take the same idea but put it in your own words. In both cases, it’s important to always cite where those ideas are coming from. The EasyBib plagiarism checker can help alert you to when you need to accurately cite the sources you used.

Patchwork plagiarism

When writing a paper, you’re often sifting through multiple sources and tabs from different search engines. It’s easy to accidentally string together pieces of sentences and phrases into your own paragraphs. You may change a few words here and there, but it’s similar to the original text. Even though it’s accidental, it is still considered plagiarism. It’s important to clearly state when you’re using someone else’s words and work.

Improper citations

Depending on the class, professor, subject, or teacher, there are multiple correct citation styles and preferences. Some examples of common style guides that are followed for citations include MLA, APA, and Chicago style. When citing resources, it’s important to cite them accurately. Incorrect citations could make it impossible for a reader to track down a source and it’s considered plagiarism. There are EasyBib citation tools to help you do this.

Don’t fall victim to plagiarism pitfalls. Most of the time, you don’t even mean to commit plagiarism; rather, you’ve read so many sources from different search engines that it gets difficult to determine an original thought or well-stated fact versus someone else’s work. Or worse, you assume a statement is common knowledge, when in fact, it should be attributed to another author.

When in doubt, cite your source!

Time for a quick plagiarism quiz! 

Which of the following requires a citation?

• A chart or graph from another source
• A paraphrase of an original source
• Several sources’ ideas summarized into your own paragraph
• A direct quote
• All of the above

If you guessed option E than you’d be correct. Correct punctuation and citation of another individual’s ideas, quotes, and graphics are a pillar of good academic writing.

What if you copy your own previous writing?

Resubmitting your own original work for another class’s assignment is a form of self-plagiarism, so don’t cut corners in your writing. Draft an original piece for each class or ask your professor if you can incorporate your previous research.

What features are available with the EasyBib plagiarism checker? 

Along with providing warnings and sources for possible plagiarism, the EasyBib  plagiarism checker works alongside the other EasyBib tools, including a grammar checker  and a spell checker . You’ll receive personalized feedback on your thesis and writing structure too!

The  plagiarism checker compares your writing sample with billions of available sources online so that it detects plagiarism at every level. You’ll be notified of which phrases are too similar to current research and literature, prompting a possible rewrite or additional citation. You’ll also get feedback on your paper’s inconsistencies, such as changes in text, formatting, or style. These small details could suggest possible plagiarism within your assignment.

And speaking of citations, there are also  EasyBib citation tools  available. They help you quickly build your bibliography and avoid accidental plagiarism. Make sure you know which citation format your professor prefers!

Great! How do I start? 

Simply copy and paste or upload your essay into the checker at the top of this page. You’ll receive the first five grammar suggestions for free! To try the plagiarism checker for free, start your EasyBib Plus three-day free trial.* If you love the product and decide to opt for premium services, you’ll have access to unlimited writing suggestions and personalized feedback.

How you can avoid plagiarizing

Know the different types of plagiarism

There are several types of plagiarism, and it’s essential to understand the differences to avoid making these mistakes and prevent plagiarism in the classroom.

• Direct plagiarism: Using someone else’s exact words and using them as your own with no credit to the source. Eliminating portions of the text still qualifies as direct plagiarism.
• Patchwork plagiarism: Creating new text by combining exact phrases or sentences from multiple sources without acknowledging the original authors or sources.
• Self-plagiarism: Attempting to reuse or recycle your previous work and claiming it as a new piece of work without mentioning the source of original publication.
• Source-based plagiarism: Producing false sources within your writing or omitting one or more references from citations.

Cite your sources

Students often think of citations as a simple means of acknowledging another author's work. While this is their main purpose, there are other benefits as well.

Source citations also show readers where to go to learn more. By providing context around the citation in student papers, such as the source medium and when it was published, readers can locate the information more easily. Giving too little source information or improperly formatting it can result in unintentional plagiarism. These mistakes also make it difficult for readers to locate the original source and verify information.

Quetext's citation generator makes it easy for students to accurately cite their sources without slowing down their writing process. Once a user inputs the text, the software identifies the passages that require a citation and subsequently generates it in the style required — APA, MLA, or Chicago.

Always use a plagiarism checker

The best way to avoid severe plagiarism consequences is to use a plagiarism checker. Often, plagiarism is unintentional and results from poor paraphrasing of material found online. Using a plagiarism checker, the student can avoid accusations of any kind of plagiarism and benefit from a close review of the original material.

Quetext's plagiarism checker provides a speedy, easy process for students to receive accurate results, identifying areas of concern and providing on-page solutions.

Plagiarism Checker for Students FAQ

What are the consequences if a student is caught plagiarizing.

The consequences of plagiarism vary according to the student’s academic institution and grade level. For example, a middle school student who plagiarizes within an essay may receive a stern warning and additional instruction related to the process of citing sources or summarizing one’s thoughts.

However, students in higher education institutions guilty of plagiarism in academic papers face much steeper repercussions, including, but not limited, to failing grades and disciplinary or legal action. Factors such as the assignment itself, the instructor, and whether or not it is your first offense impact the outcome.

Depending on the severity of the situation, plagiarism can also impact a student’s reputation or future career opportunities.

How does a plagiarism checker help students?

A plagiarism checker helps students be proactive in finding instances of plagiarism before an assignment is completed and turned in with no way to correct the errors.

In addition, by identifying the potential conflicts early, students can conduct further research to find alternative sources to understand the material better and revise or rewrite the offending passages.

Plagiarism checkers also help students learn innovative writing techniques, improve their writing skills through better research and experience in summarizing ideas, and preserve academic integrity.

Do teachers use plagiarism checkers?

Many teachers use plagiarism checkers to ensure a student’s submission is 100% original work. With the rise of easy-to-use tools like Quetext, checking for authenticity and text matches is a quick and affordable process to scan millions of online data sources.

Using plagiarism checkers also allows teachers to educate their students on the importance of citing sources and the ethical responsibilities of research and opinion writing.

Plagiarism has always been a source of concern for teachers, but until now, options for manual detection have limited their opportunities to identify the problem efficiently. However, the evolution of technology in this area has made the tools more accessible than ever.

How do teachers check a paper for plagiarism?

Teachers are skilled at detecting plagiarism, especially those who have been teaching for a significant period or who teach in the areas of English or Literature. Some teachers use a simple technique of entering a sentence into a search engine to find instances of duplicate text on web pages.

However, this manner of plagiarism detection is manually intensive and dependent upon unreliable algorithms. Some may use their writer’s intuition by identifying anomalies in sentence structure, inconsistencies in vocabulary or grammar, or a combination of all of these.

Others use more sophisticated and robust plagiarism detection software, like Quetext. Quetext can scour millions of sites using DeepSearch™ technology to identify plagiarism in seconds. These tools also enable instructors to work with students to improve their writing and avoid repeating the same mistakes in the future.

Can students get in trouble for accidental plagiarism?

Yes, students can be penalized for plagiarism, even if it was an accident. Unfortunately, instructors have no way of knowing the intent behind plagiarism. Depending on the type of plagiarism, instructors may allow leeway for students to learn from their mistakes and correct the work without the threat of severe consequences.

However, repeat offenders are less likely to receive this flexibility and may face steeper penalties. Additionally, instructors of college-level courses with clear plagiarism guidelines and policies may be less inclined to let students off the hook and instead enforce severe consequences.

Is there a free plagiarism checker for students?

Yes! Quetext offers both a free and a paid subscription for students to seamlessly verify their writing. Quetext goes beyond traditional plagiarism checkers to provide students with advanced technology that puts content through three layers of evaluation in just a matter of seconds. This level of insight enables students to understand the degree to which the text has been plagiarized and decide whether to rewrite the text or use the citation assistant to cite sources.

Quetext also offers a detailed report students can use to document their editing efforts and present as proof of a plagiarism-free, 100% original content document.

Quetext's plagiarism tool also offers flexible pricing for its Pro features which facilitates the citation of online sources, attributions, and real-time feedback for writing improvement.

How can a student check for plagiarism?

Anyone can enter the text from a research paper into a search engine and find potential matches that identify instances of plagiarized content or duplicate content. However, this method is largely ineffective and does not identify every area of concern.

Students can use Quetext's free online plagiarism checker by creating an account, copying and pasting the text in question into the plagiarism checker, and receiving a comprehensive analysis with color-coded feedback, a plagiarism percentage score, and options for editing the text.

Quetext is one of the best plagiarism checkers available with high-quality insights and accurate results.

Each test document consisted of plagiarized sections from 140 sources like Wikipedia articles, news articles, open-access journal articles, websites, theses and dissertations, and PDFs.

This setup allowed us to analyze:

• The reliability of plagiarism checker tools, even when texts are edited to varying degrees
• The depth and breadth of the tools’ content databases (whether they only covered websites or also journal articles)

Read more about the research methodology

We found that free tools were frequently misleading in their advertising and were lacking in many ways compared to paid ones. Our research led to these conclusions:

• Offers a limited free version
• Finds far more plagiarism than other tools
• Detects plagiarism even in edited texts
• Won’t store or sell your documents
• Money-back happiness guarantee, with live support available
• Self-Plagiarism Checker feature allows you to check for self-plagiarism
• You need to go premium to find out your precise similarity score and view the entire report

Scribbr offers a limited free version that’s perfect for checking if your paper contains potential plagiarism. To view the full report, you need to buy the premium version, which costs between $19.95 and $39.95 depending on the word count. There’s no word limit, so you can upload as big a document as you want.

Quality of matches

Scribbr’s checker, developed in partnership with Turnitin, heavily outperformed all free and paid tools in terms of the amount of plagiarism detected: 83% vs. an average of 42% across free tools.

It performed particularly well with source types relevant to students, such as journal articles and dissertations. Importantly, Scribbr was far more successful than other tools at detecting plagiarism in heavily edited texts, showing it has no trouble with paraphrasing plagiarism.

Scribbr could also consistently provide full matches instead of partial ones, matching the whole plagiarized passage to the correct source.

You see your results in a straightforward downloadable report. Different sources are highlighted in different colors, making it more readable.

The issues identified can be fixed with Scribbr’s Citation Generator , generating correctly formatted citations wherever they are needed.

In addition, Scribbr offers a Self-Plagiarism Checker . This unique tool allows users to upload their own unpublished documents in addition to the public database, to detect any possible self-plagiarism.

However, you can’t edit your text directly in the tool, and it’s not possible to re-check your document for free.

Trustworthiness

Scribbr will not store, sell, or share your uploaded documents. Data is automatically deleted after 30 days, or students can opt to manually delete their document after the check.

Live customer support is offered in multiple languages to assist users. A guide and other resources explaining plagiarism issues are easily accessible.

Scribbr also has a happiness guarantee: if you’re not satisfied with the tool for any reason, you can ask for a new check or a refund.

• Built-in citation assistant helps to add missing citations
• Documents not stored in database
• Support options available (but no live support)
• Finds partial matches
• Not clear how the free trial works
• Monthly subscription of at least $8.25 after free trial
• Not effective for scholarly sources

Quetext offers a free trial of 500 words, after which users must pay for a premium plan.

Additionally, uploading files to Quetext is a Pro feature. If you don’t pay, you’ll have to copy-paste the text from your document instead.

The paid version costs at least $8.25 per month (more expensive plans are available), which allows you to check up to 100,000 words.

Quetext detects more plagiarism (49% on average) than any free tool, but it’s unable to match each source text fully to a single source. Different sentences are attributed to different sources.

While Quetext claims to check against academic sources, we found it didn’t perform well at identifying plagiarism from sources such as journal articles and student dissertations.

Quetext’s plagiarism report is relatively straightforward to understand and provides a useful overview. A precise percentage is shown, with similarities in the text highlighted.

However, different sources are not highlighted in different colors, making the report somewhat difficult to read. Instead, orange highlighting is used for partial matches, red for full matches.

There’s also a built-in citation assistant that can help you fix plagiarism by adding citations. Unfortunately, it’s not very robust. Citations generated this way may not be accurate, and you have to add a lot of information manually.

Quetext states that it doesn’t save your text to a database and that all text submitted remains private and encrypted.

Information about the service is available in the form of FAQs on the website, and it’s also possible to contact the company by submitting a request form.

Check out Quetext

• Free (1,000 words per scan)
• Doesn’t save uploaded documents
• Relatively user-friendly reports
• Distracting ads for other services
• Low level of plagiarism detected
• Performs very poorly with edited text
• No color coding for different sources

DupliChecker’s service is free, though you can only upload 1,000 words at a time. If you go for one of their premium plans, you can go up to 25,000.

If you do want to upgrade, a large number of different premium plans are offered on the site, which can be somewhat confusing to navigate. The cheapest is $10 a month.

The level of plagiarism detected by DupliChecker was relatively low (44%).

While the tool was able to find some plagiarism, it was unable to find any full matches. Overall, it performed about as well as other checkers like Small SEO Tools.

DupliChecker’s website is unfortunately full of ads for their other services and for similar sites. A distracting animated “Make it unique” button appears in the report, advertising their rewriting tool.

In the online report, all plagiarized text is highlighted in one color, and it is difficult to figure out what source each source block is matched with.

The site claims not to save uploaded documents, and it deletes content after the check is complete to avoid data leakage. No live support is available, but there is a contact form on the website.

Check out DupliChecker

• Various options for document uploads
• Page is slow, somewhat confusing, and full of ads
• Scans individual sentences rather than full texts

Small SEO Tools is free to use, although you can only check 1,000 words at a time without paying.

You can run multiple checks if you need to scan more than that, although the site requires you to complete CAPTCHAs to upload multiple documents.

Small SEO Tools was unable to identify most plagiarism in our test documents, with an average of only 44%. Since it scans individual sentences separately, it was only ever able to produce partial matches.

Plagiarized text is highlighted (though all in one color), and you can click on it to be shown the source it was matched with.

The page is cluttered with a lot of ads that you can easily confuse with the buttons you need to press.

The report itself is relatively clear. While plagiarized text is highlighted in one color, the tool clearly links matched text with the source identified for it.

Small SEO Tools claims not to store your content after checking it. You don’t have to register to use the tool. Users can also contact a support email to request their personal data be erased.

Check out Small SEO Tools

• 1,000-word upload limit
• Color-coded highlighting
• Some full matches
• Citation assistant
• Live support option
• Detects a low proportion of plagiarism
• Report is hard to read
• Messy, ad-heavy page design
• Color coding doesn’t distinguish between different sources

It’s unclear whether Pre Post SEO is actually a free tool. While the website claims there’s a search query limit for visitors, the limit is not clearly specified and did not seem to apply when we tested our documents.

You can only scan up to 1,000 words per search and cannot see a complete list of matched sources (instead, you must check them manually). These limits are removed if you sign up for their premium plan, which costs $10 to $45 a month.

Pre Post SEO did find the occasional full match, but in most cases it was only able to find partial matches, like most free checkers. Overall, it performed about as well as tools like DupliChecker and Small SEO Tools.

The page where the checker is hosted is full of distracting and irrelevant ads, making the user experience frustrating.

A different color was used for verbatim plagiarism and paraphrasing plagiarism, but the tool’s judgment was often wrong. Other than that, the same color was used for different sources, which made the report hard to read.

Pre Post SEO states that it does not store or sell your documents. There is a live support option on the site and a form you can use to request support.

• Language and citation assistant available
• Does not sell or share documents with third parties
• Finds a relatively low percentage of plagiarism
• Same colors used for different sources

Despite the way it’s advertised, Grammarly’s checker is not free. All you can do is see a screen that tells you there’s plagiarism in your text without giving you any details of where it is, how much of it there is, or what the sources are.

After this you’ll be directed to download the Grammarly app and subscribe to their premium service ($30 per month). There’s a limit of 100,000 characters (about 20,000 words) even after paying.

Grammarly was able to find more full matches than most free tools. However, it performed particularly poorly with academic sources and received a low percentage overall, scoring a total of 40%.

As a premium service, Grammarly has a clearer and more visually appealing style than most free checkers. The original formatting of the document remains mostly intact, but the tool uses the same color for all sources, making the results hard to parse.

The subscription also gets you a language and style tool and a citation assistant.

Grammarly does not store, sell, or share documents with third parties.

The site provides a support page with tips, tutorials, and FAQs, and you can submit a question via a form. Live support is not available.

Check out Grammarly

• Free to use (1,000-word limit)
• Does not store or sell your document
• Technical issues with long documents
• Difficult to match text with sources in the report
• Different sources highlighted in the same color

Plagiarism Detector is free to use and users do not need to register. However, there is a limit of 1,000 words per document. By paying, you can raise this limit to 25,000 words per document.

Plagiarism Detector’s performed about as well as other 100% free tools (40%).

The tool was mostly only able to find partial matches, attributing individual sentences to one or more sources.

Plagiarism Detector’s reports are somewhat difficult to read. The same colors are used for different sources, and hovering over a plagiarized section doesn’t show you the source. Instead, you need to find it in a separate list.

Plagiarism Detector states that it will not store or sell your documents. No live support is available, but there is a help request form.

Check out Plagiarism Detector

• Offers a citation generator
• Difficult to match text with sources in the downloadable report
• Scans sentence by sentence —rarely gets a full match

It’s unclear whether Check-plagiarism.com is actually free. The site describes the free upload limit in a confusing way, allowing you a certain number of “queries” (sentences) per month. However, these limits are not clearly specified and did not seem to apply when we tested our documents.

Check-plagiarism.com performed slightly worse than most 100% free tools, scoring a total of 39%.

While the tool was able to find some full matches, it mostly found partial matches.

The same color was used for different sources, which made the report hard to read. A different color was used for verbatim plagiarism and paraphrasing plagiarism, but the tool was often wrong.

You can check up to 1,000 words at once for free. 

In the downloadable report, the format of the text is mostly retained. The report provides a long list of sources that are difficult to cross-reference with the text above.

The version of the report shown on the site itself is slightly better, as a box next to the plagiarized text allows you to see the text identified as the source. There is a “rewrite” function, along with a (manual) citation tool.

Check-plagiarism.com claims that the reports generated on their site are “highly secured and un-accessible.”

There are some FAQs listed on the site, but the answers provided are not very clear. They have live messaging support along with a contact form.

Check out Check-plagiarism.com

• Genuinely free for most purposes (1,000-word upload limit)
• Lots of distracting ads
• Unable to find most of the plagiarism
• Same highlight colors for different sources

Search Engine Reports is free to use, and users do not need to register. However, there is a limit of 1,000 words per scan. By paying, you can raise this limit to 30,000 words per scan.

The methodology this tool uses to find matches appears highly unreliable. It seems to simply search Google for each sentence in your document, counting it as plagiarism if it finds a match.

It identified only a low proportion of the plagiarism (38%) in our test documents. Due to its methodology, it was usually unable to find full matches, and it performed particularly poorly with scholarly sources such as dissertations and journal articles.

The report shown on the site gives a list of individual sentences marked as plagiarized or original. You can click a link next to each source, but all it does is google the sentence in question. The downloadable report highlights plagiarism within the text and shows a list of sources, but it doesn’t clearly link each sentence with a source.

There is also a language statistics function that lets you see words that appear frequently in the text to help limit repetition.

Search Engine Reports claims not to store any uploaded content in their database. There is no live support, but there is a contact form.

Check out Search Engine Reports

• Uploaded documents not stored/sold
• Detects a very low amount of plagiarism
• Misleading about costs—only free for five documents
• Low word limit of 800
• Lots of distracting ads and pop-ups

The tool claims it’s free, but it actually only allows you to upload five documents before requiring you to sign up for one of their many premium plans. These documents have an unusually low word limit of 800.

The premium plans offer options to increase (but not remove) this word limit. The cheapest is $15 per month, which only increases the limit to 1,000 words—a limit many other tools offer for free.

Plagiarismchecker.co gave some of the worst results out of all the checkers we tested, with an average of 30%. It was never able to provide a full match for a source text, only partial.

The tool is frustrating to use due to the high number of ads it displays and the low word limit.

The downloadable report sometimes didn’t include the plagiarism percentage, making it impossible to know how much of the text was plagiarized/original.

The report itself is difficult to read. All plagiarized text is highlighted in one color and is not clearly matched with the source identified for it.

The site claims that uploaded content is not stored in a database or shared with others. It also claims that “our advanced AI-powered algorithm ensures that your content must be protected under the copyright laws.” It’s not clear what this means.

While the site claims to have 24-hour support, there is no live support. There is a contact form on the site.

Yes, Scribbr offers a limited free version of its plagiarism checker in partnership with Turnitin. It uses Turnitin’s industry-leading plagiarism detection technology and has access to most content databases.

Run a free plagiarism check

If you’re a university representative, you can contact the sales department of Turnitin .

Plagiarism can be detected by your professor or readers if the tone, formatting, or style of your text is different in different parts of your paper, or if they’re familiar with the plagiarized source.

Many universities also use plagiarism detection software like Turnitin’s, which compares your text to a large database of other sources, flagging any similarities that come up.

It can be easier than you think to commit plagiarism by accident. Consider using a plagiarism checker prior to submitting your paper to ensure you haven’t missed any citations.

The accuracy depends on the plagiarism checker you use. Per our in-depth research , Scribbr is the most accurate plagiarism checker. Many free plagiarism checkers fail to detect all plagiarism or falsely flag text as plagiarism.

Plagiarism checkers work by using advanced database software to scan for matches between your text and existing texts. Their accuracy is determined by two factors: the algorithm (which recognizes the plagiarism) and the size of the database (with which your document is compared).

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

• 99.3 billion current and historical webpages.
• 8 million publications from more than 1,700 publishers such as Springer, IEEE, Elsevier, Wiley-Blackwell, and Taylor & Francis.

Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.

Definition of Plagiarism

But before checking for plagiarism everyone should know, What Is Plagiarism?

“The act of pretension where you take one’s words and make them your own it can include ideas, thoughts, or any material that you can see/hear and make a copy of.”

If we talk in a legalistic manner then taking someone’s copyright and claiming it to be yours is unintentional plagiarism.

Self-Plagiarism

The concept of thinking that, self-plagiarism is only copying some other's paintings or borrowing someone else's unique idea. In my thoughts like "copying" and "borrowing" can cover the seriousness of the offense.

According to the Oxford Dictionary Plagiarism is:

“The practice of taking someone else's work or ideas and passing them off as one's own”

In precise words, plagiarism is an act of fraud. It involves both stealing someone else's artwork and lying approximately it in a while.

Necessity of AI Plagiarism Checker Over Time

DupliChecker's AI plagiarism checker utilizes artificial intelligence to enhance the precision of detecting plagiarism by analyzing various text elements, such as syntax, writing pattern, tone, and rhythm of words. This inclusion of AI simplifies to check AI plagiarism across different domains.

How Does AI Plagiarism Checker Differs from Traditional Methods?

The working of an AI plagiarism checker differs from traditional methods as it organizes your data and analyzes it with advanced machine learning and Natural Language Processing techniques. Later, this AI plagiarism detector compares the comprehended information with millions of web pages’ data available in its databases to find similarities. Lastly, it displays AI plagiarism detected in your content while letting you know its exact percentage. This entire method differs from traditional plagiarism detection methods that use string-matching techniques and provide an approximate estimation of plagiarism that needs to be more accurate.

We know We would! As it can help in many ways, one of which is finding a copy of original content over the internet and informing about it while you are sipping your coffee in dim light, “Sounds Cool”.

You need an excellent memory because while reading so many documents you might keep on forgetting the duplication and sources.

Isn’t it enough reason why a plagiarism scanner is used?

Free plagiarism checker for you to enjoy

Essay plagiarism checker free with accurate percentage.

When dealing with an academic task, a student often needs to check essay for plagiarism before submitting it to their professor. Many colleges and high schools set a certain limit on plagiarised content in essays, research papers, theses, and other academic papers. So, it's crucial to know the exact percentage of unique content to avoid any issues with your educator.

Unfortunately, a typical plagiarism checker free for students doesn't show the precise ratio of the original text in an essay. It simply states whether the whole text has any traces of plagiarism. This is utterly misleading and unhelpful. Even the simplest citation will make your text not 100% original, not to mention improper quotes and self-plagiarism. So, you'll be left with only one choice - to rewrite your essay from scratch in an attempt to get fully original content. Considering how complex and lengthy formatting rules for scholars are, crafting a 100% unique text without making a single citation or self-plagiarism mistake becomes a nearly impossible task.

That's why finding out an exact percentage of non-unique text in their paper is the number one priority for many students. And our professional online plagiarism checker can help you with that. Find out an accurate plagiarism score for your essay in mere minutes and impress your strict professor with superior writing!

Using our plagiarism detector is also nothing close to rocket science. All you have to do is:

• Copy your text
• Paste your paper into the designated tab
• Get prompt and precise results

Can Plagiarism Be Detected on PDF?

Plagiarism has been a challenge for a long time in writing. It's easy to find information online, which might make some people use it without saying where it came from. But plagiarism isn't just taking someone else's words. Sometimes, we might do it by accident or even use our own old work without mentioning it.

When people plagiarize, they can get into serious trouble. They might lose others' trust or even face legal problems. Luckily, we now have tools to detect plagiarism. But what about PDF files? Let's look at how we can check these files for plagiarism.

PDF is a commonly used file format

PDF stands for Portable Document Format. It's a popular way to share files because it keeps the layout the same no matter what device or computer program you use to open it. People often use PDF files for homework, work projects, and research papers.

Why do so many people like using PDF files? Here are some reasons:

• Consistency: What you see is what others get, regardless of the device or software they're using.
• Compatibility: Nearly every computer and mobile device can open PDF files without special software.
• Security: PDFs can be password-protected and encrypted, making them ideal for sensitive documents.
• Versatility: They can contain text, images, links, and even interactive elements.

Since PDF files are used so much, it's important to know how to check a paper for plagiarism when it's a PDF. But can we really do this?

Can plagiarism be detected on PDF?

Yes, plagiarism can be detected in PDF files. Modern plagiarism detection tools can check many types of files, including PDFs. This is important to make sure people are honest in school and at work, especially since many final papers are turned in as PDFs.

When you need to check PDF for plagiarism, it works much like checking other types of files. Most plagiarism detection tools can easily read PDFs. Here's how it usually works:

• The tool extracts words from the PDF
• It compares these words to a vast database of sources.
• It marks any parts that match or look very similar

A good PDF plagiarism checker doesn't just look for exact matches. It can also find:

• Words that were changed a little (paraphrased)
• Text that was translated from another language
• Change in the order of words
• Words hidden in images (using OCR technology)

This careful checking helps detect different kinds of plagiarism, even in PDF files.

I tested 7 AI content detectors - they're getting dramatically better at identifying plagiarism

When I first looked at whether it's possible to fight back against AI-generated plagiarism, and how that might work, it was January 2023, just a few months into the world's exploding awareness of generative AI . More than a year later, it feels like we've been exploring generative AI for years, but we've only looked at the issue for about 18 months.

In any case, this is an updated version of that original January 2023 article. When I first tested GPT detectors, I used three: the GPT-2 Output Detector  (this is a different URL than we published before), Writer.com AI Content Detector , and Content at Scale AI Content Detection . 

Also:  How to use ChatGPT: Everything you need to know

The best result was 66% correct, from the GPT-2 Output Detector. I did another test in October 2023 and added three more: GPTZero , ZeroGPT (yes, they're different), and Writefull's GPT Detector . Now, in the summer of 2024, I'm adding QuillBot and a commercial service, Originality.ai , to the mix.

In October 2023, I removed the Writer.com AI Content Detector from our test suite because it failed back in January 2023, it failed again in October, and it failed now. See below for a comment from the company, which their team sent me after the original article was published in January.

Before I go on, though, we should discuss plagiarism and how it relates to our problem. Merriam-Webster defines " plagiarize " as "to steal and pass off (the ideas or words of another) as one's own; use (another's production) without crediting the source."

This definition fits AI-created content well. While someone using an AI tool like Notion AI or ChatGPT isn't stealing content, if that person doesn't credit the words as coming from an AI and claims them as their own, it still meets the dictionary definition of plagiarism.

Also:  The best AI image generators to try

In this experimental article, I've asked ChatGPT to help out. My words are in normal and bold text. The AI's words are italicized. After each AI-generated section, I'll show the results of the detectors. At the end of the article, we'll look at how well the detectors performed overall.

Here are the test results for the above text, which I wrote myself:

• GPT-2 Output Detector:  99.98% real 
• Content at Scale AI Content Detection:  100% highly likely to be human!
• GPTZero:  Your text is likely to be written entirely by a human
• ZeroGPT:  22% AI GPT Your Text is Most Likely Human written
• Writefull GPT Detector:  1% likely this comes from GPT-3, GPT-4 or ChatGPT
• Originality.ai:  84% Original 16% AI
• QuillBot: 45% of text is likely AI-generated

Human-written content: 5-of-7 correct

Before we move on, let's discuss what I'll consider a "correct" analysis. If the score is numeric, anything above 80% will be counted as a correct analysis, and that's being generous. If the score has a summary, I'll look at the summary and make a judgment. 

With that, let's dig in some more.

Explain why ChatGPT can be a real problem for teachers and editors when it comes to plagiarism

ChatGPT is a variant of the GPT (Generative Pre-trained Transformer) language model developed by OpenAI. It is designed to generate human-like text by predicting the next word or phrase in a given input sequence. While ChatGPT can be a useful tool for generating text and responding to prompts, it can also be a problem for teachers and editors when it comes to plagiarism.

Also:  4 ways to overcome your biggest worries about generative AI

One of the main reasons why ChatGPT can be a problem for teachers and editors is that it can generate text that is very similar to that of real human writers. This means that students or other individuals could potentially use ChatGPT to generate text that they could then submit as their own work, thereby committing plagiarism.

For teachers and editors, detecting whether a given piece of text was generated by ChatGPT or written by a human can be very difficult, as the generated text may not contain any obvious errors or discrepancies that would reveal its artificial origin. This can make it difficult for teachers and editors to identify and prevent plagiarism, as they may not be able to tell whether a given piece of text is original or copied from another source.

Overall, ChatGPT and other similar language models can be a problem for teachers and editors when it comes to plagiarism because they can generate text that is difficult to distinguish from that written by humans, making it easier for students and other individuals to commit plagiarism without being detected.

• GPT-2 Output Detector:  99.69% real
• Content at Scale AI Content Detection:  Hard to tell
• GPTZero:  100% AI
• ZeroGPT:  100% AI
• Writefull GPT Detector:  12% likely this comes from GPT-3, GPT-4 or ChatGPT
• Originality.ai: 100% AI
• QuillBot:  83% of text is likely AI-generated

AI-written content: 4-of-7 correct

Remember, text shown in italics was generated by the AI.

Show me at least three ways that I can detect ChatGPT was used to produce a piece of text

There are several ways that you can potentially detect whether ChatGPT or another language model was used to produce a piece of text. Here are three potential approaches you could use:

• Look for repetitive or unusual patterns in the text: One way to detect whether a language model was used to generate a piece of text is to look for repetitive or unusual patterns in the writing. For example, language models may repeat certain phrases or word combinations, or use unusual or inconsistent sentence structures.
• Check for lack of originality: Another way to detect whether a language model was used to generate a piece of text is to check for a lack of originality in the writing. If a piece of text appears to be copied from another source, or if it contains information that is widely available on the internet or in other sources, it could be a sign that it was generated by a language model.
• Use a plagiarism checker: Finally, you can use a plagiarism checker to check whether a piece of text appears to be copied from another source. While a plagiarism checker may not be able to definitively determine whether a language model was used to generate a piece of text, it can help you identify instances of copying or paraphrasing from other sources.
• Note when the answer is obviously wrong: I talked about this in my Notion AI review , where I spotlighted some text the AI wrote with seeming authority, but which was blatantly wrong. If a student or writer doesn't have full command of the topic being discussed, they may not spot the inaccuracies and leave them in the AI-generated response. Of course, incorrect statements aren't just the purview of an AI writing tool. Many bloggers and commenters, for example, repeat statements made by other bloggers, creating an echo chamber of completely "false facts", showing that while intelligence may be artificial, stupidity is a universal trait.

Keep in mind that it can be difficult to definitively determine whether a language model was used to generate a piece of text, and these methods may not always be effective. However, they can be useful tools to help you identify potential instances of language model-generated text.

In this set of tests, only the italicized content above was run through the checker suite.

• GPT-2 Output Detector:  99.98% fake
• Content at Scale AI Content Detection:  Passes as human
• GPTZero: 100% AI
• ZeroGPT:  99.69% AI GPT Your Text is AI/GPT Generated
• Writefull GPT Detector: 79% likely this comes from GPT-3, GPT-4 or ChatGPT
• QuillBot:  100% of text is likely AI-generated

AI-written content: 5-of-7 correct

List three plagiarism checkers that can detect ChatGPT text

It is worth noting that there is currently no plagiarism checker that is specifically designed to detect text generated by ChatGPT or other language models. While some plagiarism checkers may be able to identify certain characteristics of language model-generated text that could indicate its artificial origin, there is no guarantee that they will be able to definitively determine whether a piece of text was generated by a language model.

With that said, here are three plagiarism checkers that you might consider using to help identify potential instances of language model-generated text:

• Turnitin: Turnitin is a popular plagiarism checker that is widely used by schools and universities. It compares a piece of text to a database of other texts to identify instances of copying or paraphrasing. While it may not be able to definitively determine whether a piece of text was generated by a language model, it could potentially identify certain characteristics of language model-generated text that could indicate its artificial origin.
• PlagScan: PlagScan is another plagiarism checker that compares a piece of text to a database of other texts to identify instances of copying or paraphrasing. Like Turnitin, it may be able to identify certain characteristics of language model-generated text that could indicate its artificial origin, but it is not specifically designed to detect language model-generated text.
• Copyleaks: Copyleaks is a plagiarism checker that uses advanced machine learning algorithms to scan a piece of text and compare it to a database of other texts to identify instances of copying or paraphrasing. While it may be able to identify certain characteristics of language model-generated text, it is not specifically designed to detect language model-generated text.

It is worth noting that no plagiarism checker is completely foolproof, and there is always the possibility that a piece of language model-generated text could escape detection. Therefore, it is important to use plagiarism checkers as just one part of a larger strategy to detect and prevent plagiarism.

• GPT-2 Output Detector:  99.58% real
• ZeroGPT:  100% AI GPT
• Writefull GPT Detector: 86% likely this comes from GPT-3, GPT-4 or ChatGPT

Online AI plagiarism checkers

Most plagiarism detectors are used to compare writing against a corpus of other writing. For example, when a student turns in an essay, a product like Turnitin scans the submitted essay against a huge library of essays in its database, and other documents and text on the internet to determine if the submitted essay contains already-written content.

However, the AI-writing tools generate original content, at least in theory. Yes, they build their content from whatever they've been trained on, but the words they construct are somewhat unique for each composition.

Also:  OpenAI pulls its own AI detection tool because it was performing so poorly

As such, the plagiarism checkers mentioned above probably won't work because the AI-generated content probably didn't exist in, say, another student's paper.

In this article, we're just looking at GPT detectors. But plagiarism is a big problem, and as we've seen, some choose to define plagiarism as something you claim as yours that you didn't write, while others choose to define plagiarism as something written by someone else that you claim is yours.

That distinction was never a problem until now. Now that we have non-human writers, the plagiarism distinction is more nuanced. It's up to every teacher, school, editor, and institution to decide exactly where that line is drawn.

• GPT-2 Output Detector: 99.56% real
• GPTZero: 98% human
• ZeroGPT: 16.82 AI Your text is human written
• Writefull GPT Detector: 7% likely this comes from GPT-3, GPT-4 or ChatGPT
• Originality.ai: 84% Original 16% AI
• QuillBot:  0% of text is likely AI-generated

Human-written content: 7-of-7 correct

Overall results

Overall, test results this time are dramatically better than they have been with previous tests. 

In our previous runs, none of the tests got everything right. This time, three of the seven services tested got the results correct 100% of the time.

While the overall results have improved dramatically, I would not be comfortable relying solely on these tools to validate a student's content. As has been shown, writing from non-native speakers often gets rated as generated by an AI , and even though my hand-crafted content has no longer been rated as AI, there were a few paragraphs flagged by the testers as possibly being AI-based. So, I would advocate caution before relying on the results of any (or all) of these tools.

Also: Could someone falsely accuse you of using AI-generated text? This could be why

Let's look at the individual testers and see how each performed.

GPT-2 Output Detector (Accuracy 60%)

This first tool was built using a machine-learning hub managed by New York-based AI company Hugging Face . While the company has received $40 million in funding to develop its natural language library, the GPT-2 detector appears to be a user-created tool using the Hugging Face Transformers library. Of the six tests I ran, it was accurate for four of them.

Writer.com AI Content Detector (Accuracy N/A)

Writer.com is a service that generates AI writing, oriented towards corporate teams. Its AI Content Detector tool can scan for generated content. Unfortunately, I found this tool unreliable, and it failed to generate results -- exactly the same way it did in January 2023.

After this article was originally published in January, the folks at Writer.com reached out to ZDNET. CEO May Habib had this comment to share:

Demand for the AI detector has skyrocketed. Traffic has grown 2-3x per week since we launched it a couple months ago. We've now got the necessary scaling behind it to make sure it doesn't go down, and our goal is to keep it free - and up to date to catch the latest models' outputs, including ours. If AI output is going to be used verbatim, it absolutely should be attributed.

Content at Scale AI Content Detection (Accuracy 40%)

The third tool I found was also produced by an AI content generation firm. Content at Scale pitches itself as "We Help SEO-Focused Content Marketers by Automating Content Creation." Its marketing call to action is, "Upload a list of keywords and get 2,600+ word blog posts that bypass AI content detection -- all with no human intervention!" Disturbingly, the results got worse from January -- back then, it was 50% accurate. It has not improved since.

GPTZero (Accuracy 100%)

It's not entirely clear what drives GPTZero . The company is hiring engineers and sales folks, and it runs on AWS, so there are expenses and sales involved. However, all I could find about a service offering was a place where you could register for a free account to scan more than the 5,000 words offered without login. If you're interested in this service for GPT detection, you'll have to see if they'll respond to you with more details. Accuracy has increased since the last time I ran these tests.

ZeroGPT (Accuracy 100%)

ZeroGPT seems to have matured as a service since we last looked at it. When we last looked, no company name was listed, and the site was peppered with Google ads with no apparent strategy for monetization. The service worked fairly well but seemed sketchy as heck.

That sketchy-as-heck feeling is now gone. ZeroGPT presents as any other SaaS service, complete with pricing, company name, contact information, and all the rest. It still performs quite well, so perhaps the developers decided to turn their working code into more of a working business. Accuracy increased as well. Good for them.

Writefull GPT Detector (Accuracy 80%)

Writefull sells writing support services, as well as a free taste of its tools. The GPT detector is fairly new and worked fairly well. Although not fully accurate, it did improve from 60% accurate to 80% accurate with my tests.

Originality.ai (Accuracy 100%, sort of)

Originality.ai is a commercial service that bills itself as both an AI checker and a plagiarism checker. The company sells its services based on usage credits. To give you an idea, all the scans I did for this article used a total of 30 usage credits. The company sells 2,000 credits a month for $12.95 per month. I pumped about 1,400 words through the system and used only 1.5% of the monthly allocation.

Results were great for the AI checker, but they failed 3 out of 5 times when it came to using the service as a plagiarism checker. The following screenshot claims that the text pasted in was 0% plagiarised:

That's wrong since all the text pasted into it was from this article, which has been published online for 18 months. I thought, perhaps, that the plagiarism scanner couldn't read ZDNET content, but that's not the case, as this screenshot shows:

To be fair, I didn't set out to check plagiarism checkers in this article. But since I'm using source material I know I pulled from my existing article, I figured the plagiarism checker would have slammed all of them as 100% plagiarized. In any case, Originality.ai did well on the part we set out to test, the AI checker. They get points for that.  

QuillBot (Accuracy 80%-ish)

Nothing is ever easy. The first time I ran my first test through QuillBot , it said that 45% of the text was likely generated by an AI. It wasn't. I wrote it. But then, after completing all the other tests, I returned to QuillBot to grab a screenshot for this section, fed it the same text that generated the 45% score, and, as you can see, it now reports 0% AI.

So, what are we to make of this result? Sadly, I didn't grab a screenshot of the first time I tested this text, but it highlights the concern with relying too much on AI detectors because they are also quite capable of hallucination. 

What about OpenAI's own ChatGPT detector?

Well,  OpenAI pulled it last year because the detector wasn't particularly accurate. Now, it's supposed to be 99% accurate . That's a little tough to believe because ChatGPT itself is far from 100% accurate. 

Also:  Will OpenAI's new AI detection tool put an end to student cheating?

But, in any case, as my ZDNET buddy Steven Vaughan-Nichols writes, it's not available yet. We'll give it a spin when it's released for public use. Stay tuned.

Final thoughts

First, I'll let ChatGPT have its say:  AI-driven plagiarism is a growing problem, as AI tools like Notion AI and ChatGPT can generate text that is difficult to distinguish from that written by humans. There are several ways to detect whether a piece of text was generated by an AI, such as looking for repetitive or unusual patterns, checking for a lack of originality, or using a plagiarism checker. Plagiarism checkers like Turnitin, PlagScan, and Copyleaks may be able to identify certain characteristics of language model-generated text, but they are not foolproof.

Even the specialty tools I found were woefully unsuited to the task. There was some limited improvement over my tests in January. However, I certainly wouldn't feel comfortable threatening a student's academic standing or accusing them of cheating based on the results of these tools.

Also: Surprise! AI chatbots don't increase student cheating after all, research finds

At this point, I don't think we're ready to let AI fight AI. Instead, we'll have to rely on human perception (which means folks have to pay attention) to identify works generated by an AI.

Don't immediately assume that something is machine-generated. Just because something is stupid, or wildly inaccurate, doesn't mean it was not written by a human. As we all know, humans can write some bad stuff on their own.

So, what do you think? Can you tell if a piece is AI-generated? Have you used these AI writing tools in the months since they suddenly became available? Do you think they're a help or hindrance to education and journalism? Let us know in the comments below. Here's how ChatGPT answered this:

As a language model, I can't see or interact with physical pieces of writing, so I can't tell if a piece is AI-generated or not. However, I can tell you that there are several AI writing tools that are available, and they can be used to generate a wide range of written content, including news articles, fiction, poetry, and more.

I don't have personal experience using these tools since I am just a computer program and don't have the ability to browse the internet or use physical tools. However, I can tell you that some people have found AI writing tools to be helpful in education and journalism, as they can save time and effort by automating certain tasks. Others have expressed concerns about the potential for these tools to be used to produce misleading or biased content or to replace human writers. Ultimately, whether AI writing tools are a help or hindrance depends on how they are used and the context in which they are used.

So, yeah, there's that.

Online Plagiarism Checker For Students

Writing an academic paper can be challenging when you’re not sure if it’s original enough to pass a plagiarism check. Of course, students take information from various sites before writing their own text. Sometimes, it just so happens that certain parts are very similar to your resources, making your professor think that you’ve just copied work from somewhere. That’s why it’s crucial for any modern college or university student to ensure that their work has 100% original content to maintain academic integrity.

Luckily, a free plagiarism checker online can solve this issue quickly and easily. Many cheap essay writing services use a plagiarism checker for research paper. However, students sometimes forget that they should too. But with so many options that pop up when you ask Google to “check my paper for plagiarism”, how do you choose the right one for detection? We’ve got the solution in the form of PapersOwl’s free plagiarism checker tool! Our simple tool makes it convenient to check any writing task without having to spend a dime. It works quickly and highly accurately, ensuring that you get the top grade you deserve. So, if you want to check plagiarism online before turning your task in, head over to our website and get started!

Accurate Check for Plagiarism with Percentage

Many students wishing to produce original content aren’t quite sure how to get an exact percentage of plagiarised text in their work. This percentage is important since many universities have a certain limit of non-unique words you can have in your essay for it to be considered okay. If your plagiarism search doesn’t give you the exact percentage, you can’t be sure if your assignment will go through or not.

When using a free plagiarism tool, it’s essential to have this data provided to you. Only when you have it can you decide which parts to change and which ones to chuck out to achieve your desired results. Plagiarized content is a big issue in modern educational institutions, so getting reliable and trustworthy results is vital. This is the most essential requirement when you check plagiarism.

PapersOwl’s plagiarism detection tool gives you all the information you need to fix plagiarized content. Whether you’ve fallen victim to accidental plagiarism or have tried to make your life easier by copying some text from different sources, you’ll get an accurate percentage with our plagiarism checker online. If you’re wondering how to check paper for plagiarism, it’s nothing complicated at all! Simply visit our site, paste your whole essay into the relevant text box or upload the text file, click on Check For Plagiarism, and you’ll get accurate plagiarism results in a matter of seconds. You’ll see the problematic parts with plagiarism detected highlighted, with links to where similar content exists. Our service with plagiarism detector will also give you the option to check my essay for plagiarism and then to hire a professional paper writer to fix your task quickly if you're busy with other things!

The Fastest Plagiarism Checker Online

Gaining insight into duplicate content only works if you get your results quickly. There are so many free plagiarism software online that promise to do the job for you. However, a lot of them are clunky, slow, and inaccurate. How can you produce original work without similarity detection you can trust?

PapersOwl stands out in this regard because it will detect plagiarism in seconds. This is a plagiarism scanner that’s able to perform a Swift Check to give you a uniqueness check right there and then. It also conducts a Deep Search, going through millions of sources on the internet to check for plagiarism. A document of about 1500 words takes only about 10 seconds to get processed! You get a clear plagiarism score of how much text is plagiarized and how much is original. All the sources that your essay matches are listed based on how much similarity there is in your academic writing. And on top of that, you get a handy Make It Unique button that’ll take you to an order page where you can ask our expert writers to rewrite your work and make it 100% unique.

All of this is done almost instantly, allowing students to continue do assignments without missing a beat. Not every plagiarism detection software works this quickly, making ours the best one you’ll ever use.

Plagiarism Checker Helps Boost Your Grade

A lot of students make the mistake of considering their papers automatically free from plagiarism. After all, they’ve written it themselves, so how could it be problematic? What they don’t realize is that it’s very easy to borrow some information mistakenly. Turning such a paper in can cause multiple problems, as your professor might think you haven’t done the work at all.

That is why you should always use a plagiarism scanner to test for plagiarized content in your college papers. Our online plagiarism checker for students is designed for this exact purpose. A simple, free plagiarism check could help you check plagiarism, fix any mistakes you see, and submit high-quality text that no one will question.

Our plagiarism detector has a lot going for it. It makes plagiarism detection easier than ever before. Unlike copying and pasting each passage individually into Google, simply upload the whole file into our plagiarism checker free for students, and you don’t have to do anything else. All the matches are highlighted so you know what to change.

The plagiarism test will give you a uniqueness percentage too. This will help you figure out where you stand and how much time you need to adjust anything if required. So, using our copyright checker online free to check your writing is essential. This way, you’ll submit the task only when you’re sure it meets the level of uniqueness required by your school. As a result, your grades will drastically improve when you check for plagiarism.
