ChatGPT Atlas Shuts Down August 9: What Happens to Your Bookmarks and Data

Today is the deadline. OpenAI's own browser, ChatGPT Atlas, is scheduled to stop working on August 9, 2026 -- less than ten months after it launched. If you made Atlas your everyday browser, the thing to know is that your browser data does not move by itself. Bookmarks, open tabs and history stay behind unless you export them, and cookies and signed-in sessions cannot be carried into another browser at all. The reassurance: your ChatGPT conversations are stored separately and are not going anywhere. This page covers exactly what you lose, what you keep, and the five minutes of work that saves the rest.

Key Takeaways

• Atlas is scheduled to stop working on August 9, 2026. OpenAI says that after that date Atlas "may no longer open, browse, or support browser-based agentic workflows."
• Bookmarks, open tabs and browsing history do not transfer automatically. Export them yourself, today, or they are gone with the browser.
• Cookies and signed-in sessions cannot be imported into another browser. Expect to log back in to sites in Chrome. Know your passwords before you close Atlas for the last time.
• Your ChatGPT chat history is safe. It lives in your ChatGPT account, not in the browser, and stays available on the web, phone and desktop apps.
• This is a retirement, not a bug. OpenAI announced it on July 9, 2026 and calls it an "approx. 30 day wind down period."
• Nothing about your ChatGPT plan changes. Free, Go, Plus and Pro are unaffected. You are not losing a feature you pay for.
• Where to go next: a normal browser for browsing, the ChatGPT Chrome extension or sidebar for help while you browse, and the new ChatGPT desktop app for agent-style tasks.

What Is Actually Happening on August 9?

OpenAI is switching Atlas off. In its ChatGPT release notes, OpenAI says it is "deprecating Atlas as we bring browser-based agentic capabilities into ChatGPT and Codex," and that "Atlas is scheduled to stop working on August 9, 2026." Its migration article is blunter about the consequence: "After that date, Atlas may no longer open, browse, or support browser-based agentic workflows."

Read that wording carefully, because it is deliberately hedged. OpenAI says "scheduled to" and "may no longer," not "will stop at midnight." In practice, treat August 9 as the last day you can rely on Atlas rather than as a guaranteed moment of death. Either way the instruction is the same: get your data out now, because nobody is promising it will still open tomorrow.

What You Lose and What You Keep

This is the whole decision in one table. Everything below comes from OpenAI's own migration article.

The last row is the one that calms most people down. OpenAI states plainly that "ChatGPT conversation history is separate from Atlas browser data," and that you can keep using those conversations in ChatGPT, "subject to your plan, workspace settings, and account access." Losing the browser does not lose the chats.

How to Get Your Bookmarks Out (Five Minutes)

Do this before you close Atlas today. OpenAI's migration article publishes the exact steps, and they are the standard browser export flow rather than anything Atlas-specific.

Export from Atlas: open Atlas, open your bookmarks menu or bookmark manager, choose the option to export bookmarks, and save the HTML file somewhere you will find it again. Your Downloads folder is fine.

Import into Chrome: open Chrome, select More, then Bookmarks and lists, then Import bookmarks and settings. Choose the HTML file you just exported, select Open, then Done.

One thing that trips people up afterwards: OpenAI notes that "Chrome may place imported bookmarks in a new imported folder or in Other bookmarks." If your bookmarks bar looks empty after the import, open Chrome's bookmark manager and look in those two places before assuming it failed.

While you are in there, do the two things the export does not cover. Copy the URLs of any open tabs you care about into a note, because tabs do not transfer. And check that you actually know the passwords for the sites Atlas was keeping you signed in to, because OpenAI says cookies and active sessions "cannot be imported into another browser." A password manager makes this a non-event; browser-remembered logins make it a bad afternoon.

A word of caution on the cookie export OpenAI offers: it warns you to "not share cookie or session files unless you trust the recipient and understand what access the files may provide." Those files are the keys to your logged-in accounts. Treat them like passwords, and delete the export once you are done with it.

What Should You Use Instead?

It depends on which half of Atlas you actually used. Atlas was two things bolted together: a normal web browser, and a browser an AI agent could drive on your behalf. OpenAI is replacing them in different places.

OpenAI's argument is that the browser was the wrong container. It says it is "building on what we learned from Atlas to bring a more capable browser experience to ChatGPT, including multiple tabs, downloads, improved navigation, and account login support where available." In other words, the browsing features are moving inside ChatGPT rather than disappearing. Note the repeated "where available" -- OpenAI does not promise every one of these to every user, and it says availability of the desktop app and Chrome extension "may depend on your plan, region, device, browser, and workspace settings."

There is also a security reason not to linger. OpenAI's own answer to "Will Atlas keep receiving security updates?" is no: "Atlas is being discontinued, so you should move to a supported browser experience before August 9, 2026. Browsers require ongoing security maintenance, and we do not want users to remain on a discontinued browser that may degrade or stop receiving security updates." A browser that stops getting patches is a genuinely bad thing to keep using. If Atlas still opens on August 10, that is not a reason to keep browsing in it.

A Ten-Month Browser

The timeline is short enough to be worth stating plainly, because it is the honest answer to "should I trust the next one of these?" OpenAI introduced ChatGPT Atlas on October 21, 2025. It announced the retirement on July 9, 2026 -- the same day it reshuffled its desktop apps and wound down group chats -- and gave users what its FAQ calls "an approx. 30 day wind down period." Total lifespan: under ten months.

The practical lesson for a non-technical reader is not to panic about AI products generally -- it is to keep anything you would miss out of a brand-new app's exclusive storage. Bookmarks in a nine-month-old browser, notes in a beta app, files in a preview feature: export them somewhere boring and durable, and a shutdown becomes an inconvenience instead of a loss.

Do You Need to Do Anything?

Act today if you installed Atlas and used it for real browsing. Export bookmarks, copy open-tab URLs, confirm you know your passwords. That is the entire task and it takes about five minutes.

Do nothing if you only ever used ChatGPT on the web, in the phone app, or in the desktop app. Atlas was a separate download. If you never installed it, nothing about your ChatGPT changes today -- and the free plan is in fact getting better this month, not worse.

Do nothing about your subscription either. Atlas was not a paid feature and its removal does not change what Free, Go, Plus or Pro include. If you were already weighing the plans for other reasons, is ChatGPT Plus worth it in 2026 walks through that separately, and the best free AI chatbot in 2026 covers the no-cost options.

The bottom line: Atlas is going away today, your chats are safe, and the only thing genuinely at risk is the browser data you never thought about. Spend five minutes exporting it and there is nothing else to do.
