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 professional 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 paper for plagiarism and then to hire a professional 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 working on their 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.

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.

The EasyBib plagiarism checker is conveniently available 24 hours a day and seven days a week. You can cancel anytime.  Check your paper for free today!.

Frequently asked questions

Extensive testing proves that Scribbr’s plagiarism checker is one of the most accurate plagiarism checkers on the market in 2022.

The software detects everything from exact word matches to synonym swapping. It also has access to a full range of source types, including open- and restricted-access journal articles, theses and dissertations, websites, PDFs, and news articles.

Scribbr’s  Plagiarism Checker is powered by elements of Turnitin’s Similarity Checker , namely the plagiarism detection software and the Internet Archive and Premium Scholarly Publications content databases .

The add-on AI detector is powered by Scribbr’s proprietary software.

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.

At the moment we do not offer a monthly subscription for the Scribbr Plagiarism Checker. Plagiarism checks can be bought separately — prices depend on the size of your document.

Your writing stays private. Your submissions to Scribbr are not published in any public database, so no other plagiarism checker (including those used by universities) will see them.

The free report tells you if your text contains potential plagiarism and other writing issues. The premium report gives you the resources you need to review issues in detail and resolve them.

Generating your (free or premium) plagiarism report takes between 1 and 10 minutes, depending on the document size.

In that time, your document is compared to the world’s largest content database, with over 99 billion webpages and 8 million publications.

Scribbr’s plagiarism checker offers complete support for 20 languages, including English, Spanish, German, Arabic, and Dutch.

The add-on AI Detector and AI Proofreader are only available in English.

The complete list of supported languages:

If your university uses Turnitin, the result will be very similar to what you see at Scribbr.

The only possible difference is that your university may compare your submission to a private database containing previously submitted student papers. Scribbr does not have access to these private databases (and neither do other plagiarism checkers).

Luckily, many papers, theses, and dissertations are also published in public databases that Scribbr does have access to.

Testimonials.

First, I love Trinka. Congratulations on developing something that extensively aids editing, especially critical grammar conventions and word count reductions.

James Smith

I've been using Trinka for four months now, and I have extensive experience with other grammar checker systems. I've used the proofreader for two ten-page papers, and I must admit, I'm quite impressed by its quality and usefulness. I am very satisfied with Trinka and strongly recommend it for academic proofreading.

Emmanuel Lochin

Writing texts with correct English grammar and style is not an easy task for people who speak other languages. Sometimes you cannot find little mistakes in your document without help and moreover for academic writing. I tried Trinka AI as a tool of automatic correction and was quite glad with the suggested corrections and the feedback. With the feedback you understand why the suggested change must be taken into account.

Rosa Diaz Sandoval

Trinka has a robust proofreading feature that allows me to effortlessly upload entire manuscript documents and receive fully tracked changes in a single step. Moreover, its unique supporting tools such as citation checker and journal finder, significantly enhance the efficiency of my research endeavours.

Fouad Khalifa

I just wanted to say thank you for such a great and free service, all the other grammar checkers and writing assistants I have tried don’t have nearly the depth of features let alone all available on a free subscription. As a student with little income available I am extremely grateful that unlike all others companies you don’t limit features on the free plan. This is a fantastic product and given the income I would definitely upgrade to the premium. I've let all my fellow students know about Trinka as it is seriously a life saver.

Jesse Rumball-Smith

I have mainly used it to improve the language, grammar, and syntax of the scientific manuscripts that I write for national and international biomedical journals. I have found the interface to be user friendly and the procedure itself is efficient and hassle-free. The auto-edit is a great help and the supplementary page with the revision summary is an excellent idea.

Dr. Farooq Rathore

Trinka AI is a great tool to help beginners in research publication. Its grammar editing, online proofreading with file download, citation checker, plagiarism checker, paraphraser, and journal finder provide amazing features at your fingertips. Even the free Trinka Basic plan can be invaluable for researchers in their early stages or at PG levels, helping them improve project reports and papers to meet publication standards. Overall, I'm extremely impressed with Trinka AI, as it stands out among research writing tools. Give it a try and you will love it! Thanks Trinka AI team for this valuable tool.

Noor Al-rishi

It's been a wonderful experience using Trinka and I almost can't submit any manuscript without re-evaluating with it. In summary, Trinka has been a life-saver.

I trust and use Trinka as a final spot check for my edited documents. It helps me find the few remaining errors that I have missed during the primary editing. I really like using this platform for my writing. One particular feature that works well for me is the thumbs down button.

Stumpf Curtis

I think Trinka.ai is a very interesting and potentially useful idea, especially for editors/publishers/journals. I found it very useful when I checked my editing work on the platform.

Dyke Gareth

I am happy with the overall performance. I have been using Grammarly for a long while, but when it comes to academic or technical writing, Trinka is definitely a much better option. Academic document settings and auto file edit are my favorite features.

Trinka has become my go-to tool for grammar corrections. The AI-powered corrections and language enhancements made writing a lot more easier. Now I am able to focus more on research than on writing an error-free document.

Plagiarism Checker by Quetext

Free plagiarism checker: how it works, enter text into plagiarism detection tool.

We make it simple. Just copy and paste all content from your document into our plagiarism checker and hit the ‘Check Plagiarism’ button to get started.

Evaluate text for plagiarism

Our plagiarism detection tool uses DeepSearch™ Technology to identify any content throughout your document that might be plagiarized. We identify plagiarized content by running the text through three steps:

• 1.) Contextual Analysis
• 2.) Fuzzy Matching
• 3.) Conditional Scoring

Accurate plagiarism results

After evaluating the text against billions of internet sources, you will be provided with a plagiarism score showing the percentage of text that is an exact or near-match to existing text online.

Resolve plagiarism risk and use citations

Our ColorGrade™ feedback feature highlights exact matches vs. near-exact or “fuzzy” matches with corresponding colors. From there, you can resolve plagiarism issues by deleting or altering the at-risk copy. Or, you can use our handy “Cite Source” feature to generate citations in MLA, APA, and Chicago formats and insert the citations directly into your document.

Plagiarism Checker Benefits

Whether producing original content or verifying that of others, there’s a lot to gain from using a plagiarism checker. Accurate, automatic detection of duplicate content facilitates the copy-checking process for teachers, students, content writers, and more. Results showing the exact percentage of plagiarized content allows users to see exactly how much text has been copied and where they need to re-word.

For Teachers

Before homework can be graded for quality, it must first be confirmed as original. Our easy-to-use tool arms teachers with a simple, effective way to verify and grade students’ work. Educators at all levels can benefit from ensuring academic integrity through a comprehensive plagiarism check. From K-12, all the way through higher education, teachers are faced with the task of verifying the originality of the work of dozens, if not hundreds, of students each year. Automating this process frees teachers up to focus on the quality of work, rather than be bogged down by its originality.

For Students

While the prevalence of academic plagiarism is on the rise, much of it is arguably unintentional. A simple, yet accurate and comprehensive, plagiarism checker offers students peace of mind when submitting written content for grading. It is much easier to do a quick check for potential plagiarism before submission rather than convince a teacher after the fact that your academic integrity is not in question. And Quetext even takes checking for plagiarism a step further, helping students identify and cite the source itself with our built-in citation generator.

For Copywriters

Plagiarism risk is not restricted to academia. Anyone tasked with writing for an individual or business has an ethical and legal responsibility to produce original content. On top of that, content writers are often tasked with producing content on topics outside of their wheelhouse, leaving them reliant on the work of others for their research. Our plagiarism checker gives content writers a quick and easy method to prevent copyright infringement. Checking even lengthy pieces of writing takes only a few minutes, keeping companies’ public content in check and writers’ integrity intact.

Types of Plagiarism

It’s important to understand that plagiarism expands far beyond just copying someone else’s work word-for-word. There are several different types of plagiarism that should be avoided.

Self-Plagiarism

Many believe that, as long as they produced the work at some point in the past, they can include it in future pieces. However, even if you were the original author, that original work must be cited in order to not be flagged as plagiarism. Treat your past self as a totally separate author; be sure to include all relevant citations and quotations, the same as you would for any other source.

Patchwork Plagiarism

Patchwork plagiarism is the act of piecing together a "patchwork" of existing content to form something new. Assembling unoriginal content in this manner often involves some paraphrasing, with only slight changes. This type of plagiarism can be tricky and can certainly occur unintentionally, especially in academia. Since academic writing is largely based on the research of others, a well-meaning student can inadvertently end up plagiarizing.

Mosaic Plagiarism

Mosaic plagiarism is synonymous with patchwork plagiarism. It describes the process of loosely rearranging or restating another's work without issuing proper credit. It can occur accidentally or intentionally. For authors, mosaic plagiarism endangers their academic integrity or reputation as a writer. For those checking content originality, such as teachers, mosaic plagiarism can easily appear to be original content, which can make mosaic plagiarism especially difficult to detect manually.

Accidental Plagiarism

Plagiarism doesn’t have to be intentional to still be considered plagiarism — even in early academia, where students are just learning how to properly cite others’ work. While there may be no ill intent from the student, most schools have policies explicitly treating accidental plagiarism the same as intentional plagiarism. Students are expected to know how to properly issue credit to other authors. Similarly, content writers risk damage to their reputation if they produce plagiarized content, regardless of intent.

Plagiarism Checker FAQ

What is plagiarism.

Plagiarism is representing someone else’s work as your own. In educational contexts, there are differing definitions of plagiarism depending on the institution. Plagiarism is considered a violation of academic integrity and a breach of journalistic ethics.

What percentage of a paper can be plagiarized (or copied) and still be considered unique?

Generally speaking, similar or exact copies of another source should be kept under 15% for the total text of the article/paper/essay. As a best practice, citations should be used whenever using another source word-for-word.

What’s the difference between deliberate and accidental plagiarism?

Deliberate plagiarism is purposely copying works from books, articles, webpages, or someone else’s paper and representing it as your original work. Alternatively, accidental plagiarism occurs in a few different ways:

• Incorrectly citing another person’s works
• Failing to paraphrase another person’s works - even when citing it correctly
• Reusing your own previous papers and inadvertently representing it as a new idea

What are the consequences of plagiarism?

The consequences for plagiarizing another person’s works vary. But broadly speaking, the types of consequences can be grouped by person and profession.

Plagiarism consequences for students

Maintaining academic integrity is a top priority for every educational institution. As already mentioned, ignorance of how to properly cite sources is not an excuse for plagiarism. It is the student’s responsibility to ensure they are submitting work that has not been plagiarized.

Failure to do so can result in disciplinary action, including an automatic failed grade, removal from a class, or expulsion from a school or university. Students who are allowed to continue at their institution following an act of plagiarism may encounter mistrust and additional scrutiny from teachers and instructors.

Plagiarism consequences for copywriters

Copywriters stake their reputation (and by extension, that of their client or company) on their writing. All copywriters must produce completely original content for their clients.

The consequences for plagiarism here are clear: Copywriters who plagiarize the content of others will quickly find it difficult to obtain paying assignments. Similar to academic situations, it is the copywriter’s own responsibility to ensure that their content is 100% original.

Plagiarism consequences for journalists

Journalists are held to exceptionally high standards of integrity in their writing. A journalist who produces plagiarized content jeopardizes the trust of their readers and publishers. Plagiarism can instantly reduce a journalist’s career by a large margin. The ethical and legal standards issued to journalists are clear: Produce original, well-cited content or find another field.

How to Check for Plagiarism: Ensuring Your Work is Original

Plagiarism is a serious issue, both in academic and professional settings. It involves using someone else’s ideas or words without properly citing them. Fortunately, there are several tools and techniques available to help you check your work for plagiarism before you submit it.

Here’s a guide to navigating plagiarism checkers and ensuring your writing is original:

Understanding Plagiarism Checkers:

• What they do: Plagiarism checkers are software programs that scan your text against a massive database of web pages, articles, and academic journals. They identify any significant matches, highlighting potential plagiarism.
• Peace of mind: Knowing your work is original reduces stress and avoids accusations of plagiarism.
• Catching unintentional mistakes: Even paraphrasing without proper citation can be flagged, prompting you to double-check your references.
• Not perfect: Plagiarism checkers are powerful, but they can’t catch everything. For instance, they may miss paraphrased content that retains the original meaning.
• Limited databases: Free checkers might have smaller databases, potentially missing less common sources.

Using a Plagiarism Checker:

There are several free and paid plagiarism checkers available online. Here’s a general process for using them:

• Choose a checker: Consider factors like features, database size, and cost. Free options are great for basic checks, while paid services might offer more in-depth analysis.
• Upload your text: Most checkers allow you to copy and paste your text or upload a document file.
• Run the scan: Initiate the plagiarism check and wait for the results.
• Analyze the report: The report will highlight any matches. Review each flagged section carefully.

Beyond the Checker: Avoiding Plagiarism

• Proper citation: Always cite your sources correctly, following the appropriate style guide (e.g., MLA, APA).
• Paraphrase effectively: Don’t simply copy and change a few words. Rephrase the information in your own words, but still cite the source.
• Focus on understanding: The goal of research is to learn and develop your own ideas. Don’t rely solely on copying others’ work.

Plagiarism is a serious offense that can hurt your academic or professional career. To avoid accusations of plagiarism, it’s important to use a plagiarism checker to ensure that your work is original.

Ensuring the originality of your content is essential, and the best plagiarism checkers mentioned above can assist you in avoiding the severe consequences associated with plagiarism.

By considering factors such as content database size, user interface, additional features, and pricing plans, you can select the most suitable plagiarism checker to meet your specific needs. Invest in these reliable tools to enhance your writing integrity and achieve peace of mind.

Many plagiarism checkers are available, so it’s important to choose the right one for your needs. In this article, we’ve compared the best plagiarism checkers of 2024 and helped you choose the one that’s right for you.

We hope this article helps you to choose the right plagiarism tool to check your thesis, research manuscript, and assignments.

Plagiarism Software Process

Easily upload your thesis

Upload your thesis, paper, dissertation, or assignment to our system. All common formats like Word, PDF, Open Office, or text-only files are supported. It is also possible to upload several documents at once. The plagiarism software then does a word count of the uploaded thesis and selects the appropriate plagiarism package automatically. From here, our academic plagiarism software does the work for you.

Detect plagiarism by checking billions of sources

Next, your content is checked against millions of sources on the World Wide Web. The text is divided into sections or so-called phrases, each checked individually for plagiarism. Using special algorithms programmed based on language statistics, the phrases are compared to billions of sources for duplicates on the World Wide Web.

The same system as that used by the plagiarism software is used by universities and colleges. As the plagiarism software is available in more than 10 languages, it is not necessary for your paper to be written in English.

The plagiarism report

The plagiarism software will generate a transparent plagiarism report that shows you at a glance the rate of plagiarism in your submitted document. The lower the rate, the better. As a rule of thumb, your plagiarism rate should be under 5%, which puts you in the “green area”. The plagiarism software also marks each duplicated area in your text in color and provides the original source as a link.

Do You Have Any Questions?

How long does a plagiarism software take?

The  plagiarism software online  for a bachelor’s or master’s thesis (60-80 pages) normally takes between 10 and 20 minutes. It depends on the number of words submitted. In the case of longer pieces of work (200-300 pages), the plagiarism software can take up to an hour.

Does the plagiarism software work in other languages?

Yes! The plagiarism check works in all languages. French, Spanish, English, or German, it doesn’t matter. The plagiarism software will ensure that your academic work is plagiarism-free. Start your plagiarism check now.

Will the document I upload be saved to a database?

No! For data protection reasons, we don’t save any of our customers’ uploaded documents. We delete them from our server within 24 hours once the plagiarism software has finished with the detection! Your intellectual property belongs to you and only to you.

Do I have to register for the plagiarism software first?

No! You can just upload your document, choose your payment method, and then use the plagiarism detector without a user account or registering. It’s quick and easy! Play it safe and start your plagiarism check now.

Which sources will be used by the plagiarism software?

All publicly accessible online sources will be used by the plagiarism software. Databases where payment is required are excluded. If you have already cited a book, and it has an electronic copy, it may appear in your plagiarism report. But there is no need to worry about this if you’ve cited the book correctly — it’s simply an extra precaution.

What’s the difference between the BachelorPrint plagiarism software and Turnitin?

The BachelorPrint plagiarism software doesn’t save any uploaded work for data protection reasons, unlike Turnitin. Accordingly, we don’t rely on the same database as Turnitin. However, our plagiarism software searches billions of publicly available sources on the World Wide Web.

Information : If the work is scanned for plagiarism in advance with Turnitin, and the university also uses Turnitin, there is a considerable potential risk for the writer. As Turnitin saves the uploaded work, this will then be in their database. If the university scans the same work on it, it will then be classified as complete plagiarism . We have already heard this a few times. The student’s work therefore failed in the first instance, and they had to prove that they had written the document saved by Turnitin.

I haven't received an email with the plagiarism software. What should I do?

It’s possible that the email from the plagiarism software has gone into your spam folder. In really rare cases, our email with the plagiarism report might have been blocked by your email provider and hasn’t been received. Please contact us at [email protected] . We will email you the plagiarism report again .

Too few pages are shown in the plagiarism report. Why?

For an overview, only text passages that might contain plagiarism are shown in the plagiarism report. The other pages where no plagiarism is suspected will not be shown. So a plagiarism report with fewer pages is ideal.

Why is a section marked as suspected plagiarism even though I have cited the source?

It’s possible that a section of text is marked as suspected plagiarism even though it has already been correctly cited, for example from a book. This happens if the software finds a further online source. In this case, the suspected plagiarism can be ignored and serves as extra peace of mind. Nevertheless, you should still check to be sure that you’ve used the proper citation or referencing methods for that source.
