What ChatGPT Atlas was
ChatGPT Atlas was a web browser from OpenAI with ChatGPT built in — the official tagline was “The browser with ChatGPT built in.” It launched on October 21, 2025 on macOS worldwide for Free, Plus, Pro, and Go users (Business in beta; Enterprise and Edu enabled by plan administrators), with the option to import bookmarks, passwords, and browsing history from an existing browser during setup.
Features and current status
Features at launch included: calling ChatGPT on the page you are viewing, with ChatGPT memory so chats can draw on past conversations; Agent mode (in preview for Plus, Pro, and Business users), which could research, carry out tasks, and book appointments but — per OpenAI’s own boundaries — could not run code in the browser, download files, or install extensions, could not access other apps or the file system, and paused on sensitive sites such as financial institutions; and optional browser memories that the user could view, archive, or delete. On privacy, browsing content was not used for model training by default, and visibility could be controlled per site from the address bar.
OpenAI’s official announcement page now carries a notice that the product “has since been deprecated” and points users to ChatGPT Work and the release notes. At launch, Windows, iOS, and Android experiences were listed as “coming soon.”
Discussion in the show
In Weekly #003’s chapter “Codex 多账号与工作空间” (Codex multi-account and workspaces), while discussing tab and project management for Codex, Guizang mentions in the Chinese transcript that Dia’s designers and interaction designers had joined OpenAI, had previously worked on Atlas, and were presumably working on a browser again — so tab-and-project integration is something they would think of. This is a participant’s relay of team moves and speculation about product direction. The episode 003 chapter has the full context; an English transcript is not available.
