Deprecation announced Jul 9, 2026 - stops working Aug 9, 2026

OpenAI killed its own browser. Here is where the agentic web goes next.

OpenAI product lead James Sun announced on July 9, 2026 that ChatGPT Atlas is being sunset, with the browser scheduled to stop working on August 9. Atlas launched in October 2025 but never shipped beyond macOS - Windows, iOS and Android stayed "coming soon" for eight straight months.

Why it happened: Atlas never expanded past macOS in eight months and usage lagged behind a simpler approach. OpenAI decided agentic browsing works better folded into the main ChatGPT desktop app plus a Chrome extension than as a standalone browser.

How to migrate

Export your bookmarks to an HTML file before August 9 - Atlas will not transfer them automatically.
Back up saved passwords, cookies and open tabs manually; none of it moves on its own.
If you built agentic workflows on Atlas, test the same tasks in the ChatGPT desktop app plus Chrome extension first - it is the official successor.
If you need Windows, iOS or Android support, move to Perplexity Comet - it is the only major alternative that is not macOS-only.

FAQ

When does ChatGPT Atlas stop working?

OpenAI announced the Atlas sunset on July 9, 2026, and the browser is scheduled to stop working on August 9, 2026 - OpenAI calls that a targeted date. Your bookmarks, history and saved passwords do not transfer automatically, so export them before then. After August 9, the standalone Atlas browser no longer functions.

How do I export my bookmarks and passwords from Atlas?

Before August 9, 2026, export your Atlas bookmarks to an HTML file and back up saved passwords, cookies and open tabs manually - none of it moves to another browser on its own. Import the bookmark HTML into your new browser, and re-save each password through that browser or your password manager.

What is replacing ChatGPT Atlas?

OpenAI is folding Atlas agentic browsing into the ChatGPT desktop app plus a Chrome extension, which it calls the official successor. If you want a full standalone AI browser, Perplexity Comet is the only major option across Windows, macOS, iOS and Android; Dia, Microsoft Edge Copilot Mode and Brave Leo are strong alternatives too.

Does ChatGPT Atlas work on Windows?

No. Atlas launched on macOS in October 2025 and never shipped a public Windows, iOS or Android build in its eight months. That missing platform coverage was a main reason OpenAI shut it down. If you need AI browsing on Windows, switch to Perplexity Comet or Microsoft Edge Copilot Mode.

Will my Atlas data move to the ChatGPT desktop app automatically?

No. OpenAI has not promised any automatic transfer of Atlas bookmarks, history or passwords into the ChatGPT desktop app or another browser. Export everything by hand before August 9, 2026. The upgraded ChatGPT desktop browser supports logins, downloads and password managers, but you set it up fresh.
