Improve, fix grammar, expand, shorten, or rewrite professionally from a floating toolbar after you select text.
Chrome extension · Local-first · BYOK
Rewrite in your voice, on the page.
Draftline is a Chrome-only AI writing assistant with personas, prompts, and selection rewrite. Keep your tone memory local. Bring your own keys — or use on-device Gemini Nano when available.
Built for real writing workflows
Draftline stays out of the way until you need it — then helps you rewrite, chat, and keep a consistent voice.
Save tone rules and samples so Draftline writes more like you — not a generic assistant.
Settings, prompts, and personas stay on your device. Use Gemini Nano when available, or your own OpenAI / Anthropic / Gemini / OpenRouter key.
Ask about the page you’re on using title, URL, and a redacted text excerpt — not a full page upload pipeline.
Save custom prompts, folders, and system prompts for repeatable writing moves.
