We believe this provides you with the flexibility to use our service as frequently or infrequently as you need, without being tied to a contract or recurring fee structure.

Scribbr uses similar plagiarism software to most universities, providing the same or very similar results.
However, universities may check your work against private student paper databases, which Scribbr can’t access, possibly leading to small differences.
To help, Scribbr offers a free Self-Plagiarism Checker add-on, allowing you to manually upload your source documents to ensure you haven’t accidentally plagiarized.
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.
