Plagiarism / Text Similarity Checker

This tool compares two pieces of text you paste in and measures how much they overlap in sequences of words. It's useful for checking a draft against a source, or comparing two submissions — but it only checks the text you provide, not the wider internet.

Tips

This compares only the two texts you paste in — it does not search the web or any database, so a low score here doesn't rule out plagiarism from an outside source.
A higher percentage means more shared 5-word phrases between the two texts.
Use it as a quick sanity check, not a definitive plagiarism verdict.
