The Scribbr Plagiarism Checker uses Turnitin’s official software and compares your work against a database with billions of sources. If you purchase a plagiarism check, a self-plagiarism check is included.
The Scribbr Self-Plagiarism Checker uses sources that you upload yourself, such as previously submitted work or the work of your peers. Copying or paraphrasing too closely from unpublished works is still plagiarism, and it’s easy to do accidentally.
It’s easy! You can add sources to the Scribbr Self-Plagiarism Checker in the following formats:
