OpenAI is discontinuing its own AI web browser Atlas, but is adding a ChatGPT extension to Google Chrome as a replacement.
In October 2025, OpenAI introduced OpenAI Atlas. This AI web browser was intended to offer an alternative to traditional web browsers, but with ChatGPT in the leading role. OpenAI is now closing the book on Atlas, but redefining its destination. The standalone AI browser is finding a home as a ChatGPT extension in Google Chrome. Earlier this year, OpenAI also pulled the plug on its AI video app Sora.

“We are beginning to phase out the standalone Atlas browser and are sharing information with users about the transition to ChatGPT,” the company stated in a blog post announcing ChatGPT Work. OpenAI is, however, adding a Chrome extension to allow ChatGPT to be used directly within the browser.
“We are also updating our Chrome extension so you can use ChatGPT directly in the Chrome sidebar. 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,” according to OpenAI.
OpenAI is not the first AI company to launch its own AI browser. For instance, Perplexity has Comet, and The Browser Company launched Dia. Browsers themselves are also increasingly integrating AI, such as Google’s AI mode.
AI is therefore hard to ignore while surfing, but in this way, companies like OpenAI are trying to limit the dominance of browsers like Google Chrome, although that seems no easy task.
