Text Similarity Checker
Compare two supplied texts using local word n-gram overlap and show matching phrases with a similarity percentage.
Local overlap
Matching phrases
This compares only the two supplied texts. It is not a plagiarism detector and does not search the web or external databases.
What this tool does
Text Similarity Checker compares only the two text blocks you provide. It builds normalized word n-gram sets, measures their overlap, and lists matching phrases so you can inspect repeated passages locally.
What to expect
This is not a plagiarism detector and does not search the web, publications, private databases, or copyrighted-source indexes. The percentage is an n-gram overlap measure, not a judgment of originality or authorship.
