Coati

Side-panel assistant for the page you're on, with your own AI model, local or online, through a small program on your computer.

Coati is an assistant in your browser's side panel. Open it on any page, ask a question, and it answers using the page you are on: summaries of articles and YouTube videos, explanations, web searches. You bring the AI model. Coati works with a model on your computer (Ollama, LM Studio) or an online one (Claude, OpenAI, Mistral, OpenRouter, DeepSeek, or any OpenAI-compatible address) with your own key. Coati needs its local program. The extension alone cannot answer. A small program, coati-broker, runs on your computer, talks to the model and keeps your API keys, so the extension never holds them. Install it from getcoati.com or from the GitHub releases page; the extension's first-run tutorial links to the right download for your system. Coati only works once that program is installed. What it does with your data: - It acts only when you ask a question. Nothing is read in the background. - It sends your question, the page text the model asks for, the last 10 exchanges and any image you attach to the model you chose, and to no one else. With a local model, nothing leaves your computer. - It never reads the value of a password field. - On a page it only reads and highlights. It never clicks, types, pays, sends or signs in. - No telemetry, no analytics, no server of ours. Coati is open source (AGPL-3.0). Press Alt+Shift+C to open it.
