What is the difference between the free and premium report?

The free report tells you if your text contains potential plagiarism and other writing issues. The premium report gives you the resources you need to review issues in detail and resolve them.

Will Scribbr give the same result as my university’s plagiarism checker?

Scribbr uses similar plagiarism software to most universities in the UK, 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.
