Where Humanit wins
Humanit is purpose-built to rewrite AI text so it reads human and bypasses detectors — 10 tone modes including clause-level Ultra, plus a built-in AI detector so you can verify the result instead of guessing. It's free every day, with a native iOS app on the same engine.
Choose Humanit if… / Choose Grammarly if…
Choose Humanit if your priority is making AI text read human, verifying it with a built-in detector, and covering several writing jobs free in one place. Choose Grammarly if you specifically need a feature it's built around that Humanit doesn't replicate. They aren't mutually exclusive — Humanit is free to try, so you can run your text through it either way and compare the results yourself.
