OpenAI shuts down ChatGPT Atlas browser Aug 9; features move to desktop
Atlas users have 6 days to export bookmarks before browser access ends.
OpenAI confirmed it will shut down ChatGPT Atlas, its Chromium-based AI browser, on August 9, 2026. Announced July 9 with a roughly 30-day wind-down, the browser launched October 21, 2025, giving it a lifespan of under ten months. The company is blunt about the reason: discontinued browsers stop receiving critical security updates, and a browser sees every page you visit and password you type. That risk is compounded by recent AI-browser attacks, like sites slipping hidden commands to Copilot or disguised ad blockers reading ChatGPT conversations.
Every Atlas user must act before the deadline. OpenAI's help article confirms nothing migrates automatically: bookmarks, open tabs, and history all need to be exported manually. Bookmarks can be saved as an HTML file and imported into Chrome, Edge, or Firefox. Open tabs should be bookmarked or copied. Cookies—small files that keep you logged in—can't be imported into another browser, and OpenAI warns against sharing them because whoever holds them can impersonate you. Your ChatGPT conversations are unaffected since they live on your account, not in the browser. OpenAI is moving agentic browsing (where the AI clicks and fills forms) into the new ChatGPT desktop app, with multi-tab support, downloads, and logins. Chrome users can keep using the ChatGPT extension or sidebar.
- Atlas dies August 9, 2026; users must manually export bookmarks, tabs, and history as HTML — nothing migrates automatically.
- Cookies can't be transferred to other browsers, forcing full re-logins; OpenAI warns against sharing cookie export files.
- Agentic browsing and multi-tab features move to the ChatGPT desktop app; Chrome extension/sidebar remains as alternative.
