Free, open-source Grammarly alternative for Chrome & Safari — AI grammar checker and text rewriter for any website, powered by your own free Google Gemini API key. No account, no tracking, no subscription.
Why this job: works in the areas we cover, but does not say which job it does
What it does
- Live grammar and spelling checking. underlines appear in any text field about a second after you stop typing: Gmail, LinkedIn, X, Reddit, GitHub, anywhere
- One-click fixes. click an underline and accept the correction; Ctrl/Cmd+Z always undoes
- Sentence verification. after every accepted fix, the surrounding sentence is automatically re-checked, so word-level fixes never leave broken sentences behind
- Rewrite on demand. select text for a floating toolbar with *Improve, Fix, Shorten, Formal,* and *Casual* actions, also available from the right-click menu
- Context-aware suggestions. an LLM judges whole sentences in any language, not just pattern rules
