WebBrain

Open-source AI browser agent that chats about the current page and automates multi-step browsing tasks.

Browser extensionfreeglobal

WebBrain is an open-source browser extension that puts an AI agent in a side panel next to your tabs, letting you ask questions about the page you're on or hand it a task to click, type, and navigate through on its own. It works with a local model (llama.cpp or Ollama), a frontier cloud API of your choice, or a managed default with no setup, for Chrome, Firefox, and Edge.
