Industry-leading technology
We partner with Turnitin, the leader in plagiarism prevention software.
Our software only highlights the similarities that are most likely plagiarism. Commonly used words and phrases along with your reference list are ignored.
In partnership with Turnitin, the Scribbr Plagiarism Checker compares your document to over 70 billion web pages and 69 million scholarly publications.
We never add your paper to our database. After the check, you can delete your document right away. Your document stays yours.
Like many other plagiarism checkers, the Scribbr Plagiarism Checker identifies sentences that are exactly the same as in the original source.
However, it also detects plagiarism in paragraphs where the sentence structure is changed, synonyms are used, extra words are inserted or text from multiple sources is combined.
Compared to other well-known plagiarism checkers, the Scribbr Plagiarism Checker is more accurate and detects more plagiarism.
Why? Our database contains not only websites but also books and journal articles. Combine this with the most advanced plagiarism detection technology available, and you have the best plagiarism checker.
Thousands of students have used the Scribbr Plagiarism Checker to detect, understand and correct plagiarism.

Have you used any unpublished or private documents as sources, such as an unpublished journal manuscript or a friend’s paper?
You can now add these documents to the Own Sources Checker and compare them against your document for plagiarism.
The Own Sources Checker is an add-on tool that is temporarily free (normally $14.95) in combination with the Scribbr Plagiarism Checker.
The plagiarism percentage indicates what portion of your paper matches other sources in our database.
The percentage is accurate and does not include similarities found in, for instance, your reference list.
The plagiarism report displays a list of all the sources that match your paper and a preview that highlights the similarities.
A similarity can range from a couple words to entire sentences or paragraphs.
The structure of the report allows you to easily find the original source and cite it correctly.
You have access to advanced settings that allow you to customize your plagiarism report. You can:
After the plagiarism check is complete, you can start improving your text.
Paraphrase or quote the original source and include a proper citation. Our guide and Knowledge Base with articles about plagiarism will help you with this.
Upload a Word or PDF file of your paper. Multiple languages are supported.
Your document is compared to billions of web pages, books, journal articles and more.
Similarities are highlighted and matched to the source. Then, the plagiarism percentage is calculated.
Add missing citations or rewrite your text. Our plagiarism Knowledge Base can help you.

The Scribbr 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.
No, the Scribbr Plagiarism Checker does not publish your document in any public database (unlike other plagiarism checkers).
In addition, you can delete all your personal information and documents from the Scribbr server as soon as you’ve received your plagiarism report.
The Scribbr Plagiarism Checker, in partnership with Turnitin, compares your document against the largest and fastest-growing content database in the world:
The Scribbr Plagiarism Checker does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.
The Scribbr Plagiarism Checker compares your document against the largest plagiarism database in the world. It will detect any similarities with documents in that database.
However, you might be unsure if all of the sources you used are in that database – for example, because some of your sources are unpublished. In this case, you can make use of our Own Sources Checker. Here you can add all the sources you want to a private database and compare them with your own document.
The Scribbr Plagiarism Checker takes around 10 minutes.
For documents larger than 25,000 words it can take a bit longer. You will be shown an estimate on the order overview page.
As soon as the check is done we will send you an email.
No, you will never get a 100% match, because the Scribbr Plagiarism Checker does not store any documents in a shared database.
The Scribbr plagiarism report is similar to the report your supervisor will see, but there are two main differences:
The Scribbr Plagiarism Checker is optimized for students, which means that you will receive a detailed report with extra information and resources to fix and prevent plagiarism.
Your university might have a private database with submitted student papers that your document is compared with. The Scribbr Plagiarism Checker (or any other plagiarism checker) does not have access to this database.
However, many papers and theses are also published in public databases. The Scribbr Plagiarism Checker will compare your text with all documents that are in these public databases.
The Scribbr Plagiarism Checker checks your document for plagiarism once per upload. We recommend that you follow two simple steps to thoroughly revise all text snippets that might be plagiarized.
By following those steps, you can be confident that you have removed all plagiarism from your document. It is therefore not necessary to reupload your document for a new Plagiarism Check. If you would still like to perform a second or third check, you can purchase each new check at the regular price.
Step 1: Review every similarity found by the Plagiarism Check
Think about whether or not the match makes sense to you:
Step 2: Revise each potentially plagiarized text snippet
There are two ways you can fix a similarity:
Whether you paraphrase or quote, a citation is always required. Do you need more help revising your similarities? Have a look at our step-by-step guide.
