Frequently Asked Questions

How this detector works

The detector checks common writing signals such as repeated AI-style phrases, sentence-length uniformity, transition overuse, and vocabulary variation. It produces a heuristic estimate, not a definitive verdict.

When to trust the result

  • Use longer samples whenever possible.
  • Treat the score as one signal, not final proof.
  • Review the highlighted patterns before making a decision.
  • Expect mixed results on heavily edited or very short text.

Privacy
