About WebBrain

WebBrain is an innovative open-source AI browser extension designed for Chromium-based browsers and Firefox. It acts as a sidebar agent that empowers users to read, analyze, and automate tasks directly within their browser environment. Unique in its approach, WebBrain allows users to run locally with llama.cpp, ensuring that data remains private and that queries incur no cost, making it ideal for privacy-conscious individuals and developers alike. For those who prefer cloud-based solutions, it supports integration with popular APIs like OpenAI, Claude, and OpenRouter, among over 100 other providers. Its multilingual UI and token-efficient screenshot capabilities enhance usability across diverse workflows. Whether used for data extraction, automating repetitive tasks, or gathering insights, WebBrain offers a flexible and secure solution tailored for a broad user base, from casual users to AI enthusiasts and developers.
