About
WebBrain is a browser extension for Chrome, Firefox and Edge that puts an AI agent in a side panel. Users can ask about the current page or hand it a task, and it can click, type and navigate; Ask, Act and Dev modes control what it is allowed to do. It runs on a managed default model, a cloud API, or a local OpenAI-compatible server such as llama.cpp, Ollama or vLLM.
Use cases: browser-automation, web-scraping
