Reply Better AI is now free and private by default. Improve your drafts and write replies in any text field, with the AI running on-device (Chrome's Gemini Nano) or on your own local model (Ollama / LM Studio): no API key, and nothing leaves your machine. Prefer cloud? Bring a free Groq key or OpenRouter. One button morphs between Reply and Improve, with live streaming, a word-level diff of what changed, tone presets, and one-tap undo. Chrome and Firefox, open source, zero telemetry.

Transform your writing with this free Firefox extension! ✨ Features: • One-click improvements • Multiple styles • Custom AI prompts • Quick snippets • Works everywhere 🔒 Privacy: • OpenRouter API key • Open source • Local storage
