GemType — AI Writing Assistant

Grammarly-style grammar checking and text refinement on any website, powered by the Gemini API (bring your own key).

GemType checks your writing on every website and fixes it with one click — like Grammarly, but powered by Google's Gemini AI and your own free API key. No account, no subscription, no company server in the middle. HOW IT WORKS ✔ Type anywhere — Gmail, LinkedIn, X, Reddit, GitHub, any text field ✔ Pause for a second — mistakes get wavy underlines ✔ Click an underline — accept the fix (Ctrl/Cmd+Z always undoes) ✔ After each fix, the whole sentence is automatically re-checked REWRITE ON DEMAND Select any text and choose: Improve, Fix grammar, Shorten, Formal, or Casual. Also available from the right-click menu. Rewrites keep your meaning — corrections keep your exact wording. BRING YOUR OWN KEY (FREE) GemType uses your personal Gemini API key from Google AI Studio (aistudio.google.com/apikey — free tier, no credit card). Requests go directly from your browser to Google. We never see your text or your key.
