OpenAI shutting down ChatGPT Atlas browser after 9 months, shifts AI features to desktop app

OpenAI is shutting down Atlas, but its AI browser ambitions are still growing

OpenAI is sunsetting Atlas, the AI-powered browser it launched in October with ChatGPT at its core. But it's not giving up on the idea that AI should help people browse the web. Instead, it's taking some of the agentic browsing features it tested in Atlas and redistributing them across ChatGPT's desktop app and a Google Chrome extension. The move to shut down Atlas comes a few months after OpenAI's CEO of applications Fidji Simo told the team to cut back on "side quests," which led to the AI firm shutting down its AI video generation tool Sora. For much of the past year, the AI industry had been engaged in a war to unseat Chrome as the place where people spend most of their time online. Perplexity launched Comet, The Browser Company launched Dia, and Google and Microsoft have updated Chrome and Edge, respectively, with new AI-powered features. After a few months of experimenting, OpenAI appears to have concluded that the browser is a feature, not the destination. So it's folding Atlas's browser-like agent capabilities into the places people already work -- and that includes Chrome. OpenAI is launching a ChatGPT extension on Chrome that gives it access to the context of the page you're viewing, lets users ask questions about webpages, summarize content, or start longer tasks all from the browser. It's a direct competitor to Google's Gemini Side Panel, which performs several of the same tasks. OpenAI is also boosting its ChatGPT desktop app by featuring a more robust browser that allows users to browse websites, log into accounts, download files, and interact with web pages without leaving ChatGPT. A separate cloud browser runs remotely on OpenAI's servers as a place where the app's agents can complete tasks on a user's behalf. Together, the updates turn ChatGPT into a continuous workspace that spans Chrome, the desktop app, and an AI agent.

OpenAI to Retire ChatGPT Atlas Browser Less Than a Year After Launch

OpenAI's ChatGPT Atlas is headed for the 2026 tech graveyard. The company is "sunsetting" the browser as it pivots to the in-browsing capabilities in the revamped ChatGPT desktop app. OpenAI disclosed Atlas's retirement in a Thursday post introducing a more powerful ChatGPT desktop app, following reports that the company planned on turning it into a "superapp." The new desktop app combines the company's Codex coding tool, a new built-in browser, and "ChatGPT Work," which can perform actions across your other apps and files. "These capabilities build on what we learned from Atlas and from the users who helped us understand how agentic tools can make browser-based work more useful," the company said. But it also means OpenAI no longer needs Atlas as a standalone browser. In a tweet, OpenAI product staff member James Sun added, "The current targeted date for deprecation is 8/9, and we'll share more information in the upcoming days both in-app and via email." ChatGPT Atlas launched in October for macOS, boasting a tight integration with the company's popular chatbot. But the browser didn't break the mold either, considering it was built using Google's Chromium engine. In PCMag's hands on, we found that "practically any other browser is better than Atlas for standard web surfing." One of Atlas's main selling points was the "Agent" mode that could take control of the browser to complete tasks. But its actual performance was a mixed bag, as the AI could execute tasks more slowly than a human would. The agent mode was also limited to paid ChatGPT users. The sunsetting means the Windows version of ChatGPT Atlas has been canceled, though the ChatGPT desktop app is still available on both Mac and Windows. The company is already touting the built-in browser, noting: "You can ask ChatGPT to research a market, compare sources, pull information from websites, or open and refine files from Google Workspace and Microsoft 365 inside the app. It can use the browser to bring in fresh context, take steps across web pages, and keep the work moving while you review and guide the result." Atlas' demise follows the shutdown of the Sora app, which also lasted less than a year. Disclosure: Ziff Davis, PCMag's parent company, filed a lawsuit against OpenAI in April 2025, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.

OpenAI is shutting down the ChatGPT Atlas browser only months after its release

The company has decided to shut down ChatGPT Atlas due to these rollouts. It was only months ago that ChatGPT Atlas was the hot new AI web browser in town. After only nine months, it's already time to start saying goodbye. OpenAI has decided to shut the project down. Along with the announcement of GPT 5.6 today, the OpenAI browser team had a handful of updates to share. The first of those updates reveals that the new ChatGPT desktop app is getting a more robust in-app browser, with support for multiple tabs, a password manager, autofill, and more. Next up, Work mode will now have access to a browser in the cloud. And a side chat is rolling out to Chrome, bringing the power of ChatGPT and Codex to Google's browser. The final part of the announcement confirms the fate of ChatGPT Atlas. In a social post, OpenAI's James Sun states that the company will be sunsetting Atlas as a result of these updates. Sun goes on to say that the team used what it learned from Atlas to create the desktop app capabilities that are rolling out today. If you're an Atlas user, you'll still have some time to continue using the browser. OpenAI is keeping Atlas up for a few more weeks before it shuts it down on August 8, 2026. Sun says that the company will share more information about the deprecation in the ChatGPT app and via email over the coming days.

OpenAI is killing ChatGPT Atlas browser. I loved it, but it was an uphill race to the top

It was a trailblazer in a few ways, before it was copied down to its skeleton. When OpenAI launched its own web browser, there was plenty of skepticism as to why a frontier AI lab is even bothering with making a browser in the first place. And yet, the company went ahead and launched ChatGPT Atlas with a heavy dosage of AI features built in. Well, the days of browser ambitions are over, and it will be put on cold ice in September this year. OpenAI says it is sunsetting the short-lived browser in favor of pushing the new ChatGPT work desktop app, which already has a built-in browser as well as a cloud browser for AI agents. And now that ChatGPT is making its way to other browsers, such as Chrome, as an extension, there is little need for maintaining a dedicated browser project of its own. But why? "All these capabilities were built on what we learned from Atlas users who took a leap of faith on a new browser. You taught us how agents can help make browsing and doing work on the open web better, and we are applying these learnings to these new products," James Sung, an OpenAI executive who leads the browsing project at the company, shared in a post on X. Recommended Videos ChatGPT Atlas was launched in October last year, and it put ChatGPT at the center of the browsing experience. The design is clean and instantly familiar, and that's because it's built on top of the Chromium engine under the hood. Your extensions, bookmarks, history, and saved logins carry over without any extra setup, so it genuinely feels like settling into a browser you already know. Everything starts from the homepage, which centers around a single, unified search bar. The real story is the sidebar. Collapse the left pane, and you'll find all the ChatGPT tools you're used to, which include Search, Library, custom GPTs, Codex, and your full chat history. On the opposite side, there's a dedicated sidecar panel that slides open whenever you tap the "Ask ChatGPT" button in the top-right corner. It was a trailblazer The side panel is my favorite AI browser feature, and it has since been implemented with full force with Gemini in Chrome and Copilot in the Edge browser. Even smaller players like Opera and Firefox have implemented the formula, with even more ambitious scope in some cases. Perplexity was another core AI player that followed in the footsteps of its own AI-first browser called Comet. It even had an agent mode that could get work done autonomously on your behalf. But the challenge before Atlas was always monumental. Why use Atlas, when you have Chrome built on the same foundation and offering a more robust set of features? Then there was the familiarity aspect, as Atlas was a little too ambitious at revolutionizing the web browser experience with some really future-forward tools that offered a learning curve of their own. Then came the flood of security reports and warnings that flagged AI browsers like ChatGPT Atlas and Perplexity Comet as risky. It didn't help that Google got inspired (read: copied) some of the best capabilities of Atlas, such as tab awareness and multi-tab actions, in Chrome, effectively killing the appeal of Atlas. The journey lasted less than a year, but I appreciate that OpenAI pushed the envelope for what browsers can do with AI coming into the picture.
