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.
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 content 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you might be unsure if all of the sources you used are in that database – for example, because some of your sources are unpublished.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.

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
