OpenAI Says ChatGPT Atlas Stops Working This Weekend, and Bookmarks Will Not Transfer

OpenAI has set out what happens to ChatGPT Atlas when the browser is switched off on Sunday, 9 August 2026, and the short version is that anyone still using it has a few days to get their data out. Bookmarks, open tabs and browsing history do not move anywhere on their own, and after the cut-off the app may stop opening altogether.

The shutdown itself was announced in July, but the practical detail — what survives, what disappears, and what you have to do by hand — has only been spelled out now, five days before the deadline. This applies to every Atlas user everywhere; there is no market where the browser carries on.

What actually disappears on 9 August

OpenAI's guidance is blunt about the state of the app after the date: Atlas may no longer open, browse, or run agentic workflows. That is not a gradual wind-down with a read-only mode, so treat 9 August as a hard stop rather than a warning.

Three things need manual action before then:

• Bookmarks — these do not transfer automatically. Open the bookmark manager in Atlas and export them to an HTML file, which Chrome, Edge, Firefox and Safari can all import.
• Open tabs — a tab you have left parked for weeks is not saved anywhere. Bookmark it or paste the URL into a note.
• Browsing history — likewise not carried across. If there is a page you only know how to find through history, save it now.

Saved passwords are worth checking too. If you let Atlas store logins rather than a dedicated password manager, export or re-save them somewhere else before the browser stops launching, because recovering them afterwards is far harder than doing it today.

Your ChatGPT conversations are not affected

This is the part that has caused the most confusion, so it is worth stating plainly: ChatGPT chat history is stored in your ChatGPT account, not in the Atlas browser. Conversations, custom instructions and memory stay exactly where they are and remain available in the ChatGPT app and on the web, subject to your plan and any workspace settings.

Only the browser-side data — bookmarks, tabs, history, cookies, locally saved logins — is tied to Atlas and at risk.

What replaces it

OpenAI is not walking away from browsing, it is moving it inside ChatGPT. The desktop app has picked up a much fuller built-in browser that handles multiple tabs, downloads, website logins, autofill and password manager integration, which covers most of what people used Atlas for day to day.

Alongside that, a ChatGPT extension for Google Chrome brings page context, summarisation and task handling into a browser you already use, and agent tasks can run in a remote cloud browser rather than on your machine. The reasoning is that a chat-driven browser works better as a feature than as a separate product competing with Chrome for your default.

Choosing where to land

If you adopted Atlas for the AI layer, the ChatGPT desktop app or the Chrome extension is the closest match. If you moved to it to get away from Chrome, this is a reasonable moment to look properly at the alternatives — our Chrome versus Brave comparison covers the privacy and performance trade-offs, and Puffin's cloud browser takes a very different approach to rendering pages.

Whichever you pick, do the bookmark export first. It takes about a minute in Atlas today and is impossible once the app refuses to launch.

A short life for a high-profile launch

Atlas arrived in October 2025 as a Chromium-based browser built around the idea of chatting with the page in front of you, and it drew a great deal of attention as OpenAI's move onto Google's turf. Retiring it inside a year is an unusually quick reversal for a product of that profile, and it reflects a broader tightening of focus at the company.

For users, the lesson is a familiar one about AI-era software: features shipped fast can be withdrawn just as fast, and data that lives only inside one vendor's app is worth exporting long before a deadline appears.
