OpenAI Will Retire ChatGPT Atlas on August 9

OpenAI's migration guidance says bookmarks will not transfer automatically. Users should export them from Atlas as an HTML file and import that file into another browser, such as Chrome. Open tabs and browser history also will not move automatically, so important pages and URLs need to be saved before the cutoff.

Cookies may be exportable where Atlas provides an option, but OpenAI warns that cookie and session files are sensitive. Its guidance also says active sessions cannot be imported into another browser. ChatGPT conversation history is separate from Atlas browser data and remains available subject to a user's plan, workspace settings, and account access.

OpenAI says the replacement path is the new ChatGPT desktop app for deeper browser-based agent work. The company describes a more capable browser experience with multiple tabs, downloads, improved navigation, and account-login support where available. It also points users to the ChatGPT Chrome extension or sidebar for help alongside an existing Chrome session.

9to5Mac reported on July 9 that OpenAI executive James Sun confirmed the shutdown and the August 9 target. TechCrunch separately reported that Atlas-tested browsing features are being redistributed across the ChatGPT desktop app and a Chrome extension. Those reports support a product-consolidation reading, but OpenAI has not published Atlas usage data or a measured explanation of why the standalone browser is ending.

Workspace administrators should identify Atlas users, update internal documentation, and treat exported cookie or session files as credentials. Teams with browser-agent workflows should also retest permissions, login behavior, downloads, and audit controls in the replacement surface instead of assuming Atlas state or automation will transfer intact.
