What is WebBrain

Product Overview

WebBrain is a free, open-source browser extension that adds AI agent capabilities to Chrome, Firefox and Edge. It reads pages, extracts data and automates browser tasks such as clicking, typing, scrolling and navigating, and can download media from a page. The agent runs with a user's choice of model, including local llama.cpp, OpenAI, Claude and OpenRouter, so it can operate offline with a local model. Ask mode is read-only by default and consequential actions require confirmation, with no telemetry and no accounts.
