OpenAI’s ChatGPT Atlas browser is scheduled to stop working on Aug. 9, 2026, leaving users little time to preserve browser data and test a replacement. OpenAI is moving browser-based agentic capabilities into ChatGPT and Codex, but organizations should verify data, permissions, and essential workflows before uninstalling Atlas. Preserve browser data before the deadlineUnder OpenAI’s Atlas migration guidance, users should export bookmarks as an HTML file and import them into another browser. ChatGPT conversations are separate from Atlas browser data and should remain accessible, subject to the user’s plan, workspace settings, and account access. Cloud Work conversations sync across web, mobile, and desktop; locally stored conversations remain on the computer where they were created.
