Frequently Asked Questions

Our tool breaks your text into segments and compares them against billions of web pages, academic databases, and published content. It identifies matching passages and calculates a similarity percentage for each match and an overall score.

The similarity percentage shows how much of your text matches content found online. A score of 0-10% is considered low (likely original), 10-30% is moderate (some common phrases may match), and above 30% warrants closer review for potential plagiarism.
