Frequently Asked Questions
What does this similarity checker actually do?
It compares two text samples using word-overlap analysis to measure how similar they are. Higher percentage = more shared vocabulary.
Is this a legal plagiarism detection tool?
No. This tool is for originality guidance only. Results are not a legal determination of copyright status or plagiarism.
What similarity percentage is considered too high?
As a rough guide: under 20% is typically fine, 20-40% suggests review recommended, above 40% warrants significant revision.
Why might two original texts show similarity?
Technical or industry-specific texts naturally share specialized vocabulary. Context and phrasing matter more than word overlap alone.
Is my text sent to any server for analysis?
No — all comparison is done locally in your browser. Your text is never transmitted.
