RIP ChatGPT Atlas
Shut down · August 2026
OpenAI shut down ChatGPT Atlas on August 9, 2026, 292 days after launching it on October 21, 2025. The Chromium-based browser never left macOS — the promised Windows, iOS and Android builds never shipped, not even as public betas — and it made no measurable dent in Chrome's roughly 68% share. OpenAI folded the work into a ChatGPT Chrome extension and an upgraded browser mode in the ChatGPT desktop app rather than keep a standalone browser alive.
Last known pricing: Free download on macOS for Free, Plus, Pro and Go accounts; agent mode required a Plus, Pro or Business plan.

Overview
ChatGPT Atlas: OpenAI's AI browser, launched October 2025 and shut down August 2026
ChatGPT Atlas was OpenAI's attempt to turn the web browser into a ChatGPT surface. Announced on October 21, 2025, it was a Chromium-based desktop browser with ChatGPT built into a sidebar that could read the page you were on, and an agent mode that could carry out multi-step tasks — booking travel, shopping, running a piece of data analysis — inside the browser itself. OpenAI shut ChatGPT Atlas down on August 9, 2026, 292 days after launch.
Atlas shipped on macOS only. Windows, iOS and Android were promised at launch and never arrived, not even as public betas, which capped the addressable audience at a slice of one desktop platform for the product's entire life. It never made a measurable dent in Chrome's roughly 68% global share.
Key features
- ChatGPT sidebar that could answer questions about the current page, summarise it, and rewrite selected text
- Agent mode for multi-step browsing tasks, restricted to Plus, Pro and Business accounts
- Browser memories, letting ChatGPT carry context between sessions and sites
- Chromium engine, so standard web compatibility and extension behaviour came along for free
- Free to download worldwide on macOS for Free, Plus, Pro and Go accounts
Ideal use case
Atlas was aimed at people who already lived inside ChatGPT and wanted the assistant present on every page rather than in a separate tab — research-heavy work, comparison shopping, and repetitive multi-step web tasks that agent mode could take over.
How ChatGPT Atlas differentiated
Atlas was the first AI browser shipped by a frontier lab rather than a startup or an established browser vendor, which is what made its failure informative. Perplexity's Comet and The Browser Company's Dia were competing for the same idea from the independent side. OpenAI had the assistant everyone already used, distribution to hundreds of millions of accounts, and it still could not make a standalone browser stand up as a business.
What replaced it
OpenAI did not abandon the ambition, only the form factor. The capabilities moved into a ChatGPT extension for Google Chrome and an upgraded browser mode inside the ChatGPT desktop application, picking up multi-tab support, file downloads, improved navigation and account login handling. Atlas users were told to export bookmarks and browsing data before the August 9, 2026 shutdown.
FAQ
When did ChatGPT Atlas shut down? ChatGPT Atlas shut down on August 9, 2026, 292 days after it launched on October 21, 2025. OpenAI announced the decision roughly a month earlier, in July 2026.
Why did OpenAI shut down ChatGPT Atlas? It never demonstrated that a standalone AI browser could be a sustainable product. Atlas stayed macOS-only for its whole life, the promised Windows, iOS and Android versions never shipped, and it made no measurable impact on Chrome's roughly 68% market share.
What replaced ChatGPT Atlas? A ChatGPT extension for Google Chrome and an upgraded browser mode in the ChatGPT desktop app. The agentic browsing capability survived; the separate browser did not.
Was ChatGPT Atlas free? Yes, the download was free on macOS for Free, Plus, Pro and Go accounts, but agent mode required a paid Plus, Pro or Business plan.
What are the alternatives to ChatGPT Atlas? Perplexity's Comet and Dia are the closest standalone AI browsers still shipping. For the agent capability rather than the browser, browser-agent platforms such as Browser Use and Browserbase remain active.
tl;dr
