What Grammarly AI Humanizer does
Grammarly AI Humanizer is a humanizer tool. 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.
Pricing: Included in Grammarly Premium ($12/mo annual) and Business plans.
Bundled AI detector: No — pair with a standalone detector like GPTZero or Originality.ai
Strengths and weaknesses
What works
- Built into an app most professionals already have installed (browser, desktop, Docs)
- Focuses on clarity and flow rather than aggressive detection evasion
- Backed by Grammarly's long-standing grammar and tone engine
What to watch for
- Not designed primarily to defeat detectors — it prioritizes readability over stealth
- No standalone free tier for the humanizer feature specifically
