Which should you pick?

Choose AI Detector if

  • You want a transparent, focused detector for AI text with no platform lock-in.
  • You want to see each detector's contribution and judged uncertainty.

Choose Copyleaks if

  • You need plagiarism, AI and authorship checks inside one integrity platform.
  • You want a subscription workflow rather than a stand-alone tool.
Honest limits
  • Detection is a statistical estimate, not proof of authorship. Neither tool determines who wrote something.
  • Both are vulnerable to editing and rewriting, and both can produce false positives. Verify before acting.
