Detailed plagiarism report
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:
- Search or exclude content databases.
- Exclude your bibliography.
- Ignore similarities in quotes.
- Change the threshold for small matches to exclude similarities that are not plagiarism.
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.

Frequently asked questions
The Class Master 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 Class Master 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 Class Master server as soon as you’ve received your plagiarism report.
The Class Master Plagiarism Checker, in partnership with Turnitin, compares your document against the largest and fastest-growing content database in the world:
- Over 70 billion current and historical web pages.
- Over 69 million journal articles and books from more than 1,700 publishers such as Springer, IEEE, Elsevier, Wiley-Blackwell and Taylor & Francis.
The Class Master 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 Class Master Plagiarism Checker will only check your paper for plagiarism once. Don’t worry – if you have followed our guide, as well as our articles on avoiding plagiarism and citing sources, there is no need to perform a second plagiarism check.
If you still want to perform a second plagiarism check, you’ll have to buy a new check at the standard price.
The Class Master 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 Class Master Plagiarism Checker does not store any documents in a shared database.
The Class Master plagiarism report is similar to the report your supervisor will see, but there are two main differences:
Access to more detail and resources
The Class Master 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.
No access to private university databases
Your university might have a private database with submitted student papers that your document is compared with. The Class Master 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 Class Master Plagiarism Checker will compare your text with all documents that are in these public databases.
