Detection performance
Grammarly AI Humanizer: Grammarly is explicit that the feature is meant to improve natural tone rather than guarantee detector evasion, which sets it apart from bypass-first competitors.
Humbot: Independent testers found its free tier underperforms its marketing claims; paid tier results were not independently verified at the same depth.
AI detector included: Neither tool bundles a built-in detector — pair either with GPTZero or Originality.ai.
