About Browser Brain AI Agent

** Browser Brain — An AI That Actually Works Inside Your Browser ** Most AI browser extensions are just chat boxes bolted onto the side of your screen. Browser Brain is different. Browser Brain is an autonomous AI agent that lives inside your browser, giving it the ability to see your tabs, understand the page you’re on, recall what you’ve already browsed, and help you complete real web tasks—not just talk about them. Use it to understand the page you’re on, automate multi-step web tasks, and instantly recall information from your browsing context (tabs, history, bookmarks). No subscriptions, no lock-in: connect your own OpenRouter key for pay-as-you-go access to a wide range of free and premium models, or run Ollama or LM Studio locally for complete privacy and zero per-request cost. Use it across any Chromium-based browser (Chrome, Edge, Brave, Opera, etc.)—no forced “AI browser” ecosystem. Freely choose from many AI models and switch anytime based on cost, speed, or quality. ** True browser agent capabilities (beyond just AI chat) ** 1.) Access and reason over open tabs. Chat with and ask questions about the current website to get context-aware help. 2.) Find lost pages you once visited (history recall) and bookmarks you forgot where you put long ago. 3.) Interact with browser content and guide or perform multi-step actions. 4.) Upload documents, images, screenshots, data or code files for instant analysis and summarization. The agent can also "see" your browser: snap screenshots of your current view for context, or analyze visual elements on the page. 5.) Export & backups: Save chats to a file for records, sharing, or documentation. ** Privacy, Control & Transparency ** Local-first by design: When you choose Ollama, your prompts and processing for local models stay entirely on your device—ensuring complete privacy with no data leaving your machine.
