## What it is
WebBrain is an open-source AI browser agent extension for Chrome, Firefox, and Edge that puts an LLM-powered assistant in a side panel. It can chat about the current page and automate multi-step tasks like clicking, typing, and navigating, using local models (llama.cpp, Ollama) or cloud LLM APIs.

## Use cases
- summarize the page I'm reading
- automate filling out web forms
- find links about a topic on a page
- let an AI agent navigate and complete multi-step web tasks
- run a browser AI assistant with a local LLM
- extract structured info from web pages
- automate repetitive browser workflows

## When to choose
- you want an AI agent that operates inside your browser on any page
- you prefer bringing your own LLM, including local Ollama or llama.cpp servers
- you need cross-browser support for Chrome, Firefox, and Edge

## When to avoid
- you need headless or server-side browser automation rather than an interactive extension
- you require a fully permissive license (it is GPL-3.0-or-later)
- you want a stable, long-proven tool rather than a newer project
