Clearfy

Clearfy is a web-based tool that checks text for AI-generated patterns and rewrites it to sound more human. You paste your writing — an essay, a blog post, any piece of text — and Clearfy runs it through the same detectors your school or publisher might use, including Turnitin, GPTZero, Copyleaks, and others. It gives you a score showing how likely the text is flagged as AI-written, and a humanizer mode that rewrites passages to mimic natural human writing. No subscriptions, just pay-as-you-go credits that never expire.

The humanizer is trained on over a million pages of authentic human writing, not synthetic AI content. That means its output avoids the repetitive sentence structures and robotic phrasing that detectors look for. Clearfy also offers sentence-level insights — it highlights which specific sentences feel AI-generated, so you can rewrite only what needs changing. It supports over 100 languages and works on mobile browsers, so you can review and revise on the go. The interface is straightforward: upload or paste text, check it, and hit the humanizer button.

Students are the clearest fit — especially those worried about AI detection in schoolwork — but it also works for content creators and bloggers who use AI assistants and want to refine the output before publishing. Anyone producing written content that needs to pass as human-written will find Clearfy useful. It's a no-fuss tool that does exactly what it says: detect and humanize.
