Tips for best results

Not a database check

Unlike Turnitin or iThenticate, this doesn't cross-reference published academic papers. It analyses writing patterns, consistency, and AI-generation signals — a different kind of originality check, but valid for different use cases.

How to read the score

Above 80: strongly original. 60-80: mostly original with some concerns. Below 60: significant sections flagged — investigate each one manually before trusting the output.

Pair with a database tool

Use this as a first-pass filter on any incoming document. For academic or legal submissions, pair it with a database-backed plagiarism service — they catch different things.
