OpenAI explains what will happen when ChatGPT Atlas shuts down this weekend

OpenAI is ending support for the ChatGPT Atlas browser, which is set to stop working on August 9.

Users should export bookmarks manually; chat history will remain, but browsing and agentic features may disappear.

OpenAI is directing users to the ChatGPT desktop app and Chrome extension as replacements.

Mac users in particular need to move quickly to preserve data and switch to supported tools before Atlas goes offline.
