Chrome extension for running multiple isolated browser sessions in one window. Each session has its own cookies, login state, and proxy. No separate app, 2-minute setup. $3.99/month after a 2-day free trial. What makes it different: it ships with a native MCP server. Connect Claude, Cursor, or ChatGPT to your sessions and let the AI control them. Open URLs, take screenshots, click, type, navigate inside a fully isolated context. Nothing leaves your machine.
