Open-source AI agent for Chrome. Reads and acts on the page you're on using any model you choose — OpenRouter, OpenAI, Claude, Gemini, Groq, or a local model. Keys stay in your browser. MIT, no account, no telemetry.

Hey PH. I spent the last few weeks building this because I wanted the "AI drives my browser" thing without handing my browsing to one AI company. So: bring your own model (any OpenAI-compatible endpoint or the Anthropic API, including local Ollama / LM Studio), keys stay in your browser, and the whole thing is MIT so you can read exactly what it does. It reads the page and acts on it, with a plan/ask/auto toggle so you decide how much rope it gets. Two things I'm proud of that sound small: a Test button that checks whether a model can actually do tool calls + vision before you waste time on it, and the agent always hands logins and captchas back to you instead of trying to be clever. It's early. If you tell me which model you ran it with and where it fell over, that's worth more to me than an upvote.

Love that keys never leave the browser, that's the right call. One thing I'd love to see is a per-site allowlist or blocklist so I can lock it down to only run on domains I trust, with a quick toggle for new sites. Would make it feel safer to leave running in the background across my workflow.

Keys staying in the browser is a nice touch, and switching between local and cloud models without restarting the extension worked smoothly when I tried it on a docs page.
