English Polisher

Fix grammar or rewrite text to sound human — using free AI (Gemini, Chrome built-in AI, Groq, OpenRouter) or Claude.

English Polisher cleans up your writing or drafts it for you — without leaving the page. POLISH MODE Paste or select text and choose one: • Fix — corrects grammar, spelling, and punctuation while keeping your meaning and tone • Humanize — rewrites stiff, robotic, or AI-sounding text so it reads like a real person • Shorten — makes it tighter and clearer ASK MODE Give a plain instruction like "reply to this email" or "write a short bio," and optionally paste the email or notes as context. Get a natural, human-sounding draft you can copy or insert. IN-PLACE EDITING Select text in any editable field (Gmail, comment boxes, text areas), then right-click or press a keyboard shortcut to replace it in place — with undo. IN-FIELD BUTTON (EXPERIMENTAL, OFF BY DEFAULT) Optionally enable a small button that appears in the corner of text boxes on the web. Click it for Fix / Humanize / Shorten and the field is rewritten in place. FREE TO RUN • Google Gemini free tier — no credit card required • Chrome's built-in AI (Gemini Nano) — runs entirely on your device, no key needed • Also supports Groq, OpenRouter, and Anthropic Claude PRIVATE BY DESIGN No accounts, no analytics, no backend. Your API key is stored in your browser and your text is sent only to the AI provider you choose (or nowhere at all with the on-device model). You bring an API key from your chosen provider; the extension is free and open source.
