rewrite.so — Write naturally in any language

Three native-sounding rewrites of any text input — faithful, casual, formal. Write naturally in any language; double-tap Shift.

Write naturally in any language. rewrite.so is a Chrome extension that turns whatever you typed into three native-sounding rewrites — right inside the text field, in many of the websites you already use. Working in a second language, learning a new one, or posting in public? Double-tap Shift in any supported input. Three streaming rewrites appear in place: - Faithful — fix typos, grammar, and clarity while staying close to what you wrote. - Casual — warmer, shorter, conversational. Good for Slack, DMs, comments. - Formal — clear and professional. Good for emails and shared docs. Press 1, 2, or 3 (or click) to replace the text in place. No copy-paste. No separate editor. No tab switch. What it's good for: - Cross-language work: write your draft in your native language, get three English (or any target-language) tones to pick from before you send. Slack to a teammate in casual; a client email in formal; a PR description in neutral. - Learning a language: write in your target language and compare three native phrasings side by side. Pro Learning Mode adds a 💡 button on each rewrite — click it to see, in your UI language, why the wording was changed. - Public posting: think out loud in your native language; pick the safest English phrasing before hitting Post on X, Reddit, Hacker News, or any public thread. Multi-language by default. CJK and European languages are first-class — write Chinese, Japanese, Korean, German, Spanish, French, English, and more, in either direction. Set a fixed target language or let it auto-detect from the page. Privacy by design: - rewrite.so does not store the text you rewrite. - rewrite.so does not store the rewritten results. - Password, hidden, credit-card, CVV, OTP, token, readonly, and disabled fields are excluded — hardcoded, not a setting. - Text is sent only when you actively trigger a rewrite. - The extension does not read your browsing history. - No ads, no tracking cookies, no third-party analytics. Works in regular text inputs, textareas, and many contenteditable editors including Reddit, X (Twitter), and GitHub. Some complex editors are not supported yet, including Google Docs, Gmail compose, and inputs inside iframes. Free usage is included — 30 rewrites per month for signed-in users, all three styles, language auto-detection. Signed-in users can also configure Bring Your Own Key (BYOK) with any OpenAI-compatible endpoint (OpenAI, Anthropic, Azure, Groq, DeepSeek, etc.) at no extra cost from us. Pro ($7.99/month on annual billing) unlocks 2,000 rewrites/month on our hosted model, priority support, and Learning Mode — the 💡 "why was this changed" explanations.
