OpenSidekick
Open-source AI browser agent that runs any model you choose
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.
