# Web Butler

> A Chrome extension that drives the browser through a user's existing ChatGPT, Claude, or Grok subscription.

Web Butler adds a compact prompt to every page. It can answer questions using page context, run browser errands, create long-form reports, and install persistent page modifications. The project is open source and uses the user's existing AI subscription rather than a separate model API subscription.
