ChatGPT's July 2026 App Shake-Up Explained: What You Keep and What You Lose
On July 9, 2026, OpenAI merged Chat, Work, and Codex into one new ChatGPT desktop app and renamed the old app ChatGPT Classic. It also stopped new group chats and set the Atlas browser to shut down on August 9. Your normal chats and history are unaffected -- but a few things are changing or going away.
The short version: on July 9, 2026, OpenAI reshuffled how you get to ChatGPT on a computer and quietly retired two things some people use. It merged Chat, Work, and Codex into one new desktop app, renamed the old app "ChatGPT Classic," stopped letting anyone start new group chats, and set its Atlas browser to shut down on August 9. None of this touches your normal one-on-one chats, your history, or the free tier. But if you use the desktop app, group chats, or Atlas, a few things are changing under you. This page explains what actually changed for an everyday user, what you keep, and what you need to do (usually nothing).
Key Takeaways
- A new ChatGPT desktop app launched July 9, 2026. It combines Chat, Work, and Codex in one app for macOS and Windows, globally. The old app you had is now called ChatGPT Classic.
- ChatGPT Classic still works. It keeps getting model updates, bug fixes, and security patches -- but the new agent features (Work and Codex) only live in the new app.
- Group chats are being retired. From July 9 you cannot create new group chats or join one by invite link. Existing ones stay for now; when they go read-only, you keep everything already shared in them.
- The Atlas browser is shutting down on August 9, 2026. Export your bookmarks, cookies, and passwords before then -- they do not move automatically. Your ChatGPT history is separate and stays.
- ChatGPT Sites entered public beta. You can build a simple website or app inside ChatGPT, but it is on Pro, Pro Lite, and Edu now (Plus following), and not on Free or Go.
- Nothing changes for basic chatting. The website, the phone apps, your saved conversations, and the free tier all work the same. Most people do not need to do anything.
What Actually Changed on July 9?
OpenAI shipped a bundle of changes at once, and it is easy to feel like ChatGPT got more complicated. Here is the plain breakdown of what each change means for a normal user, sorted by how likely it is to affect you.
| Change | What it means for you | Do you need to act? |
|---|---|---|
| New desktop app | Chat, Work, and Codex now live in one app; the old app becomes ChatGPT Classic | Only if you use the desktop app -- follow the prompt to update, or keep Classic |
| Group chats retired | No new group chats or invite-link joins as of July 9 | Only if you use group chats -- save what you need |
| Atlas browser shutting down | Atlas stops working August 9, 2026 | Only if you use Atlas -- export your data first |
| ChatGPT Sites (public beta) | Build a basic site/app inside ChatGPT | Optional; not on Free or Go |
| ChatGPT Work (agent) | A helper that does longer multi-step tasks for you | Optional; paid plans only, not Free or Go |
If you only ever open chatgpt.com or the phone app to ask questions, the honest answer is that almost nothing changed for you. The reshuffle is mostly about the desktop app and a couple of features being wound down.
The New Desktop App and "ChatGPT Classic"
The biggest visible change is on the desktop. OpenAI released a new ChatGPT desktop app for macOS and Windows that puts three things in one place: Chat (normal questions and conversation), Work (an agent for longer tasks), and Codex (its coding tool). Because that new app is bigger and more feature-packed, OpenAI kept the older, simpler desktop app around under a new name: ChatGPT Classic.
You do not have to rush. According to OpenAI's release notes, if you already use the Codex app it updates into the new app automatically; if you use the previous ChatGPT desktop app, a prompt inside it offers the new version. ChatGPT Classic "continues to receive model updates, bug fixes, security patches," so it will keep working -- it just will not get the new Work and Codex agent features. If you liked the simpler app and only want to chat, staying on Classic for now is a reasonable choice.
Here is the difference in plain terms:
| App | What it is | Who it suits |
|---|---|---|
| New ChatGPT desktop app | Chat + Work + Codex in one app; can use local files and a built-in browser with permission | People who want the new agent features |
| ChatGPT Classic | The previous, simpler desktop app; still updated and patched | People who just want to chat and prefer the old app |
Group Chats Are Going Away
If you ever used ChatGPT group chats -- the feature that let you pull friends or coworkers into the same conversation with ChatGPT -- that is being retired. Beginning July 9, 2026, you can no longer create new group chats, turn an existing conversation into one, or join a group chat through an invite link on web, iOS, or Android.
What you keep matters here. Existing group chats "will remain available and can continue to be used for now," and when one eventually becomes read-only, OpenAI says you "retain access to the messages, files, and images already shared there." So you will not lose the content -- you just cannot start new group conversations. Your regular one-on-one ChatGPT conversations are completely unaffected. If a group chat holds something you care about, save or copy it out while you still can.
The Atlas Browser Shuts Down August 9
This is the change most likely to catch someone off guard. OpenAI is deprecating Atlas, its web browser, and it is scheduled to stop working on August 9, 2026. If you switched to Atlas as your everyday browser, treat this as a deadline.
The important part: your browser data does not move by itself. Atlas bookmarks, open tabs, and browsing history "will not transfer automatically." Before August 9 you can export your cookies and passwords to the new ChatGPT desktop app and your bookmarks to Chrome, and you should manually save any important pages or URLs from your open tabs and history. One reassurance: your ChatGPT conversation history is stored separately from the browser and stays in your account. OpenAI says it is folding browser-style features into ChatGPT itself, including multiple tabs and downloads, and points Atlas users toward the new desktop app or the ChatGPT Chrome extension.

What About ChatGPT Sites and ChatGPT Work?
These are the two new features in the bundle, and for a non-technical reader the key question is simply "do I get them, and do I need them?" Both are optional, and both skip the free tier.
ChatGPT Sites lets you turn an idea into a simple interactive website or lightweight app -- a dashboard, a tracker, a calendar -- without leaving ChatGPT, then preview and share it by URL. It is in public beta for Pro, Pro Lite, and Edu users now, with Plus following "over the coming days," and it is not available on Free or Go. Public publishing and the wider beta are also not available in the EEA, Switzerland, or the UK at launch.
ChatGPT Work is an agent for longer, multi-step tasks -- research, analysis, and producing finished documents, spreadsheets, or presentations while you follow along and approve steps. On web and mobile it is rolling out to paid plans except Free and Go, with Pro, Pro Lite, Enterprise, and Edu first and Plus and Business following. If you are on the free tier, neither of these is something you are missing out on today. If you want the plain-English version of what an "agent" like Work actually does, our AI agent guide covers it.
Should You Care?
For most everyday users, this is a "good to know," not a "do something now." Basic chatting on the website and phone apps is unchanged, your history is safe, and the free tier still does what it did yesterday -- including the newly upgraded ChatGPT Voice that reached free users this week.
Do nothing if you only chat on the web or phone -- nothing you use went away. Check your setup if you use the desktop app (decide between the new app and Classic), rely on group chats (save what matters, since new ones are gone), or browse with Atlas (export your data before August 9, 2026). Ignore for now if you are on Free or Go and hear about Sites or Work -- those are paid features you are not missing.
The bottom line: OpenAI is consolidating everything into one bigger app and trimming a few side features, which is more about tidying its product line than changing your daily use.

Frequently Asked Questions
Did ChatGPT change on my computer?
If you used the desktop app, yes. On July 9, 2026, OpenAI released a new ChatGPT desktop app that combines Chat, Work, and Codex. Your old app may stay installed and is now called ChatGPT Classic. The website chatgpt.com and the phone apps still work the same way for everyday chatting.
What is ChatGPT Classic?
ChatGPT Classic is the name OpenAI gave the previous desktop app after launching the new one. It still gets model updates, bug fixes, and security patches, so it keeps working. The new agent features (Work and Codex) only live in the new app. You do not have to switch immediately.
Are ChatGPT group chats gone?
Partly. Starting July 9, 2026, you can no longer create new group chats or join one by invite link on web, iOS, or Android. Existing group chats stay available for now, and when one becomes read-only you keep the messages, files, and images already in it. One-on-one chats are unaffected.
Is the Atlas browser shutting down?
Yes. OpenAI is deprecating Atlas, and it is scheduled to stop working on August 9, 2026. Before then, export anything you want to keep -- bookmarks, cookies, and passwords do not transfer automatically. Your ChatGPT conversation history is separate and stays in your account.
Do I have to do anything?
For most people, no. Everyday typing-based chats, your history, and the free tier are unchanged. Act only if you use the desktop app (a prompt will offer the new version), rely on group chats (they are winding down), or use the Atlas browser (export your data before August 9, 2026).
