OpenAI has documented a Chrome extension that lets ChatGPT control Chrome and read or act on sites where users are already signed in. The OpenAI guide says setup starts in the desktop app, with tasks launched through ChatGPT Work or Codex; availability can vary by rollout and workspace settings.
The extension can pull in context from open tabs and keep browser tasks grouped in Chrome tab groups. OpenAI also distinguishes the desktop app’s @Browser from browser-specific control through mentions such as @Chrome. The Verge reported demos showing multi-tab comparison and prompts for compiling vendor details, pricing, features, and source links.
OpenAI says the extension may request broad permissions covering website data, history, downloads, bookmarks, and tab groups. Per-site approvals and allow/block lists add controls, but workflows touching sensitive accounts still need narrow access and human checkpoints.
