OpenAI Is Shutting Down the Atlas Browser on August 9, 2026 — Here's What You Need to Do Before Then
OpenAI is closing its Atlas browser on August 9, 2026. Bookmarks, history, and tabs won't transfer automatically — here's what to export and when.
OpenAI has confirmed it is shutting down Atlas, its standalone AI browser, on August 9, 2026. The app will stop loading web pages entirely on that date. Any browser data you have stored inside Atlas, including bookmarks, open tabs, browsing history, saved passwords, and cookies, will not transfer automatically to any other application. You need to export it yourself before the deadline.
If you use Atlas, this post covers exactly what to save, how to save it, and where to go next.
A Quick Recap: What Was Atlas?
Atlas launched on October 21, 2025, as a macOS-only Chromium-based browser built around ChatGPT. The idea was a persistent AI sidebar that could learn your browsing habits over time, plus an “agent mode” that could handle tasks on your behalf, things like researching a meal plan, generating a shopping list, and adding items to a cart. Agent mode was limited to Plus, Pro, and Business subscribers; free users got a more basic sidebar experience.
It never made it off macOS. Promised versions for Windows, iOS, and Android were never released, even as public betas. Eight months after launch, OpenAI is pulling the plug.
What Happens on August 9, 2026?
On that date, Atlas stops working. The app will not load web pages or connect to OpenAI’s servers. According to OpenAI’s release notes, locally stored browsing data will remain accessible for export until August 23, 2026, after which it will be permanently deleted from OpenAI’s sync servers.
Your ChatGPT conversation history is stored separately in your ChatGPT account and will not be affected by this shutdown.
What You Need to Export Before the Deadline
This is the most important part. Nothing moves automatically. Here is what to do:
Bookmarks: Export your bookmarks as an HTML file from within Atlas, then import that file into Chrome, Safari, or whichever browser you are moving to.
Passwords and cookies: OpenAI says these can be exported to the ChatGPT desktop app. Check Atlas’s settings for the export option before August 9.
Open tabs and browsing history: There is no automatic transfer here. Go through any open tabs and manually save the URLs you want to keep, either by copying them into a notes app or importing them into another browser’s reading list. The same applies to anything in your browsing history you might want to revisit.
Custom AI instructions: If you set up any custom instructions inside Atlas, make a note of them separately. They will not carry over.
OpenAI says Atlas users will receive in-app notifications and emails about the shutdown over the coming weeks, so keep an eye on both.
Why Is OpenAI Doing This?
OpenAI has been fairly candid about the reasoning. Getting users to adopt an entirely new standalone browser turned out to be a much harder problem than embedding the same capabilities inside tools people were already using. Atlas never escaped macOS, which kept its audience small relative to cross-platform AI browsers from competitors.
There were also security concerns early on. Within days of launch, researchers demonstrated prompt injection attacks that could manipulate the AI assistant through malicious instructions embedded in web pages. A separate flaw allowed malformed URLs to expose information about previously visited sites. These problems were patched, but they added pressure to an already narrow product.
Internally, Fidji Simo, OpenAI’s CEO of applications, reportedly pushed teams to step back from what she described as “side quests” and focus on the company’s core productivity push. Atlas, as a standalone browser competing for shelf space against Chrome and Safari, appears to have fallen into that category.
What Replaces Atlas?
OpenAI is pointing users in two directions.
For everyday AI assistance while browsing, the ChatGPT Chrome extension brings a sidebar experience into Chrome without requiring you to switch browsers.
For deeper, agent-style work, the ChatGPT desktop app is OpenAI’s current answer. It combines ChatGPT, Codex, and some of what Atlas offered into a single application that can connect to files, browse the web, and handle longer-running tasks. OpenAI has said it is building on what it learned from Atlas to bring improved browser capabilities to ChatGPT, including multiple tabs, downloads, better navigation, and account login support, though no firm timeline has been given.
A Note for Developers and Enterprise Teams
If you built integrations on top of Atlas’s proprietary extension APIs, those are being deprecated entirely. OpenAI recommends migrating to the standard ChatGPT API or the browsing capabilities in the Assistants API, but any custom work will need to be rewritten from scratch.
For organisations that deployed Atlas internally, a migration tool for exporting bookmarks, saved sessions, and custom AI instructions into a ChatGPT Work workspace is expected to be publicly available from July 28, 2026. That leaves a narrow window before the August 9 shutdown, so it is worth contacting your OpenAI account manager now if you need early access.
The Short Version
Atlas is shutting down on August 9, 2026. Nothing transfers automatically. If you use it, export your bookmarks, passwords, and any URLs you want to keep before that date. For ongoing AI-assisted browsing, the ChatGPT Chrome extension or the ChatGPT desktop app are your best options right now.
OpenAI will send notifications via email and inside the app, but do not wait for those. The export window closes, and after August 23 the data is gone.
