ChatGPT Atlas
ChatGPT Atlas was OpenAI's web browser with ChatGPT built in, released for Mac in October 2025 and closed in August 2026.
ChatGPT Atlas was a web browser made by OpenAI, with ChatGPT built into every page. You could ask about the page you were reading, and let ChatGPT browse and act on websites for you. OpenAI launched it for Mac in October 2025 and shut it down in August 2026, less than a year later.
It's worth knowing about for two reasons. You'll still see it in articles and strategy decks from that period. And what it did hasn't gone away: its browsing features moved into ChatGPT itself.
What it did
Atlas worked like an ordinary browser, with ChatGPT in a sidebar. You could ask it to summarize a page, compare products across tabs, or remember what you'd looked at earlier. In agent mode, ChatGPT could click, scroll and fill in forms on websites to finish a task.
For example, someone could open three coffee subscription pages and ask Atlas which one delivers fastest and costs least per bag. ChatGPT read all three pages and answered. In agent mode, it could then go to Fernhill Coffee's site and start the subscription.
What happened to it
According to Digital Trends' report on the shutdown, OpenAI moved Atlas's browsing into the ChatGPT desktop app and a ChatGPT browser extension, and gave browser automation for signed-in sites to Codex.
So for a brand, the lesson still holds. ChatGPT can read and use your website inside the session of the person it's working for. Your prices, product details and checkout need to work for software as well as people.
