Rewrite drafts and write replies anywhere on the web. Free AI writing assistant that runs on-device or on your own Ollama model. Reply Better AI is a free AI writing assistant for Chrome. Rewrite any draft, reply to any message in context, and fix tone, in any text box on the web. No account. No sign-up. No credit card. It can run entirely on your device, so your text never leaves your computer. ━━━ WHAT IT DOES ━━━ ✍️ IMPROVE — Polish what you already typed Select your draft, pick a style (Polish, Professional, Friendly, Concise), and get a rewrite with a word-level diff so you see exactly what changed. Good for email, cover letters, bug reports, product copy, or any message you want to sound better. 💬 REPLY — Write the answer for you Grab the message you're replying to, choose a tone (Match thread, Professional, Friendly, Concise) or Summarize, and get a reply that actually fits the conversation. Or type a free-form instruction in any language. ━━━ CHOOSE YOUR AI ENGINE ━━━ 🔒 On-device (default, free) — Chrome's built-in Gemini Nano. No key, no account, no network. Your text never leaves your computer. 🖥️ Local model (free) — Point it at Ollama, LM Studio, or any OpenAI-compatible server. Works offline. Nothing leaves your machine. Runs whichever model you already have pulled. ⚡ Groq (free) — Bring a free Groq key and get Llama 3.3 70B at very high speed, around 1,000 requests a day at no cost. 🌐 OpenRouter (paid, optional) — Hundreds of models through one key, with a searchable picker and a free-models filter. Auto mode picks the best engine you have set up and falls back if one is unavailable. ━━━ PRIVACY ━━━ • Zero telemetry. No analytics, no tracking, no servers of ours — ever. • API keys, prompts and text stay in your browser's local storage. • With the on-device or local engine, nothing leaves your computer at all. • Keys are never exposed to the pages you visit. • Open source, so you can read every line: github.com/dantnan/reply-better-ai ━━━ WHERE IT WORKS ━━━ Anywhere you type: webmail, social networks, chat apps, support desks, CMS editors, issue trackers. If the page has a normal text field, the extension works in it. A small button appears next to the field you're typing in — click it, or ignore it. Note: Google Docs is not supported yet — it renders text on a canvas, so no extension can edit it directly. Everything else with a normal text field works. ━━━ WHO IT'S FOR ━━━ Support agents answering tickets. Developers writing issues and PR descriptions. Job seekers writing outreach. Non-native English speakers who want to sound natural. Anyone who rewrites the same email three times before sending it. ━━━ FREE ━━━ Free and open source (MIT). No paid tier, no upsell, no "pro" version. If you want to pay for a premium model you pay OpenRouter directly, never us. Also available for Firefox.
