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.
Superhumanizer.ai: Marketed around volume rather than a headline bypass statistic; treat unverified claims accordingly and confirm results yourself.
AI detector included: Neither tool bundles a built-in detector — pair either with GPTZero or Originality.ai.
