What is BrowserKing?

BrowserKing is a Chrome extension that gives any LLM the ability to see and control your browser. It works like a human assistant that can:

Take screenshots and understand what's on screen
Click, type, scroll and navigate web pages
Read page content and extract information
Open tabs and work across multiple pages
Record and replay workflows for repetitive tasks

Unlike other browser agents locked to a single provider, BrowserKing lets you bring your own API key from any OpenAI-compatible provider — or use the Anthropic API directly.
