What Auto Browser is
Auto Browser is a free Chrome side-panel AI agent that reads webpages and carries out tasks described in plain English. It inspects a page’s accessibility tree and can click, type, scroll, navigate, and fill forms. If a site offers tools through WebMCP, Auto Browser can use those instead of interacting through the page’s DOM. Supported AI choices include Chrome Built-in AI (Gemini Nano), Google Gemini, OpenRouter, and local OpenAI-compatible endpoints such as Ollama and LM Studio; users can switch providers mid-conversation without losing history. Write actions require approval, arbitrary JavaScript always prompts, and banking, government, and healthcare origins are blocked by default. The extension is free to install at no cost, though Google Gemini and OpenRouter charge per request when used with the user’s API key. Basic use requires Chrome 126 or newer. The maker says the extension has no backend and does not receive or store prompts, browsing activity, conversation history, or API keys; cloud-provider prompts and relevant page context go directly from the browser to that provider.
