About WebBrain

What the tool does and who it's for

WebBrain is a free, open-source AI browser agent for Chromium-based browsers and Firefox. Functioning directly from your browser sidebar, WebBrain reads web pages, extracts structured data, and automates multi-step browsing tasks. It can run completely offline and locally via llama.cpp to ensure zero data leakage, or connect to cloud AI models by bringing your own API keys for OpenAI, Claude, OpenRouter, or 100+ OpenAI-compatible providers. WebBrain features a read-only Ask Mode by default, defense against prompt injections, token-conscious screenshot handling, and a multilingual interface.
