Webbrain

WebBrain is a free, open-source browser extension that brings AI agent capabilities to Chrome. Read pages, extract data, and automate web tasks — powered by your choice of LLM. The self-hostable alternative to proprietary browser AI plugins.

Key Features:
- Page Understanding: Reads and comprehends any web page — articles, docs, dashboards, forms
- Full Browser Agent: Click, type, scroll, navigate, and interact with pages on your behalf
- Data Extraction: Extract structured data from any page — tables, lists, links, forms
- Multi-Provider LLM: Works with local LLMs (LM Studio, Ollama, llama.cpp) and leading cloud providers (OpenAI, Anthropic Claude, Gemini, OpenRouter, etc.).
- Privacy First: Your data stays yours. Run with a local LLM for zero data leakage
- Smart Context: Automatic context management prevents token overflow

Interaction Modes:
- Ask Mode: Read-only questions about current page
- Act Mode: Full agent with browser control for automation
