Auto Browser
What Auto Browser is
Auto Browser is a Chrome side-panel AI agent that reads webpages and carries out tasks described in plain English. It can inspect a page’s accessibility tree, click, type, scroll, navigate, fill forms and handle research tasks. On pages that expose WebMCP tools, it can use those tools instead of interacting through the page. It supports Chrome Built-in AI (Gemini Nano), Google Gemini, OpenRouter and local OpenAI-compatible endpoints such as Ollama and LM Studio. You can switch providers mid-conversation while keeping the conversation history. The extension is free to install. Google Gemini and OpenRouter charge per request when you use your own API key. The maker says it has no extension backend and does not receive or store prompts, browsing activity, conversation history or API keys. With a cloud provider, prompts and relevant page context go directly from the browser to that provider; the maker says Gemini Nano and local LLM options send no data from the device through the extension. Basic use requires Chrome 126 or newer. Gemini Nano has additional browser, operating system, memory and disk requirements. Write actions require approval, arbitrary JavaScript always prompts, and banking, government and healthcare origins are blocked by default.
