What Is ChatGPT Atlas? OpenAI's Browser Explained

ChatGPT Atlas was OpenAI's web browser with ChatGPT built in, including a sidebar, optional browser memories and an agent mode that could click for you. OpenAI's help centre now says Atlas has been retired. The catch: your Atlas data doesn't move automatically, and deleting ChatGPT chats doesn't delete it.

If you've seen ChatGPT Atlas mentioned in an article or a screenshot and wondered whether you should be using it, here's the short story. It was OpenAI's own web browser, and OpenAI's help centre now says it has been retired. I still think it's worth understanding what it did, because the ideas behind it, an assistant that sits beside the page you're reading and can act for you, are showing up everywhere.

That matters for everyday users and for small-business owners alike. If anyone on your team installed Atlas, they may have saved bookmarks, passwords and browsing memories there. Everything below comes from OpenAI's own announcement and help pages.

What ChatGPT Atlas was

OpenAI described ChatGPT Atlas as a web browser built with ChatGPT at its core. Instead of copying text into a separate chat window, you had ChatGPT in a sidebar right next to the page, called Ask ChatGPT. The new tab page worked as a starting point where you could either ask a question or type a web address.

It launched on macOS first. OpenAI's announcement said the aim was for ChatGPT to understand what you were looking at, so you didn't have to paste or screenshot things to ask about them.

What the Atlas sidebar, memories and agent mode did

Three features made Atlas different from an ordinary browser:

The Ask ChatGPT sidebar: a chat panel that could see the page you had open, so you could ask for a summary, an explanation or a rewrite of what was on screen.
Browser memories: an optional feature that let ChatGPT remember context from sites you visited and bring it back later, for example asking it to summarise job postings you'd looked at the week before.
Agent mode: ChatGPT could open tabs and click around in your browser to finish a task, such as researching a topic or adding items to an online basket.

OpenAI itself called agent mode an early experience that may make mistakes on complex workflows, which is a fair warning for anything that acts on your behalf.

Atlas feature	What it did	What to know
Ask ChatGPT sidebar	Chat beside the page you're viewing	Part of the browser, not a separate app
Browser memories	Remembered context from sites you visited	Optional, and separate from your normal ChatGPT memories
Agent mode	Opened tabs and clicked to complete tasks	OpenAI described it as an early experience that could make mistakes
Incognito window	Temporarily logged you out of ChatGPT	Chats and browsing weren't saved or linked

The Atlas privacy controls OpenAI described

Because a browser sees so much of your day, the privacy settings were a big part of the story. According to OpenAI's announcement:

A toggle in the address bar let you choose which sites ChatGPT could see. With visibility off, ChatGPT couldn't view the page and no memories were created from it.
You could clear specific pages or your whole browsing history, and clearing history deleted the browser memories linked to it.
By default, OpenAI said it didn't use the content you browse to train its models. You could opt in through an "include web browsing" setting in your data controls.
Parental controls set up for ChatGPT carried over, with extra options for parents to turn off browser memories and agent mode.

The safety limits on ChatGPT Atlas agent mode

An assistant that can click on your behalf, on sites where you're logged in, is a bigger risk than one that only chats. OpenAI listed several safeguards: the agent couldn't run code in the browser, download files or install extensions, couldn't reach other apps or your file system, and paused so you could watch when it was on sensitive sites such as banks. There was also a logged-out mode to limit what it could reach.

OpenAI also said plainly that agents can be fooled by hidden instructions planted in a webpage or an email, and that its safeguards wouldn't stop every attack. That's the main lesson I'd take from Atlas for any AI agent: watch what it does, and don't give it more access than the job needs.

What happened to ChatGPT Atlas

OpenAI's help centre now states that ChatGPT Atlas has been retired and no longer receives updates. If you search for how to download it today, don't expect a working installer, and be wary of any third-party site that claims to offer one.

The help article is mostly about looking after your saved data:

Bookmarks, open tabs, browsing history and signed-in sessions don't transfer automatically to another browser.
If you exported a bookmarks file earlier, you can import it into Chrome through its bookmarks import option.
If you exported passwords to a file, import that into your new password manager and then delete the file, because it contains readable passwords.
Your ChatGPT conversations are separate from Atlas browser data, so they carry on in ChatGPT as normal.

How to deal with your ChatGPT Atlas data

This is the part people trip over. Atlas browser memories are separate from your ChatGPT memories, and deleting your ChatGPT chats doesn't delete Atlas browser memories, cookies or other Atlas data. Uninstalling the app doesn't count as deleting that data either.

Open ChatGPT's data controls from your account settings and review what's there for your ChatGPT account.
If you want Atlas-specific data removed or explained, use OpenAI's Privacy Portal or contact OpenAI Support, as the retirement article suggests.
Check passwords you saved in Atlas and move them to a password manager. For any you can't reach, use the website's own account recovery.
If you run a team, share OpenAI's retirement article with anyone who used Atlas and update any internal guides that still mention it.

OpenAI also says recovery isn't promised for data you didn't export, so it's worth asking early rather than assuming it's all still there.

What to use now that ChatGPT Atlas has gone

The Atlas idea, ChatGPT working alongside the web, hasn't vanished. OpenAI's help pages describe other routes:

Search and deep research inside ChatGPT: for questions that need sources, ChatGPT can search the web or run a longer research task and give you cited results.
The ChatGPT desktop app: OpenAI's docs list using the browser and your computer among the things the app can do, and the app is available for macOS, Windows and Linux.
Your usual browser: OpenAI's own retirement steps point people to Chrome for importing their bookmarks.

If you're unsure which tool suits which job, my guide to AI agents you can try without committing is a sensible place to compare options, and it helps to understand where ChatGPT gets its information before you rely on any answer.

ChatGPT Atlas for a small business owner

For a freelancer or small business, the practical points are simple. First, check whether anyone on your team installed Atlas and what they saved in it. Second, treat any AI browser or agent as something with access to your logged-in accounts: keep it away from banking and customer systems unless you've decided it's worth the risk. Third, keep a normal password manager, so a single app retiring never locks you out of accounts.

If you'd like help choosing and setting up AI tools in a way that protects your customer data, that's the kind of work I do as an AI consultant.

What people mix up with ChatGPT Atlas

ChatGPT versus the browser: ChatGPT is the assistant you use in the app or on the web. Atlas was a separate browser with ChatGPT built in.
Browser memories versus ChatGPT memory: OpenAI says they're separate, so changing one doesn't change the other.
Atlas versus a browser extension: Atlas was a whole browser, not an add-on for another one.
Agent mode versus a normal chat: a chat answers; an agent takes steps in your browser, which is why the safety limits matter.
