Frequently Asked Questions
How does this plagiarism checker work?
This tool compares two texts by analyzing word overlap and matching phrases. It calculates a similarity percentage based on shared words and common phrase patterns (3+ word sequences).
Is this a complete plagiarism detection tool?
This is a basic text comparison tool for local comparison between two texts. For comprehensive plagiarism detection against online sources, consider dedicated services like Turnitin or Grammarly.
What similarity percentage indicates plagiarism?
There's no universal threshold. Generally, 0-20% is low similarity, 20-40% is moderate, 40-60% is high, and above 60% is very high. Context matters - technical documents may naturally share terminology.

No, all text comparison is done locally in your browser. Your text is never sent to any server or stored anywhere.
Can I compare documents in different languages?
This tool works best with English text. It may work with other languages using Latin characters, but accuracy may vary.
