OpenAI’s AI web browser was called ChatGPT Atlas. The company introduced it on October 21, 2025, but later deprecated the browser and scheduled it to stop working on August 9, 2026. That date had passed by September 28, 2026, so Atlas is no longer an upcoming release or an available standalone browser.
What ChatGPT Atlas was
OpenAI described Atlas as “a new web browser built with ChatGPT at its core” in its October 21, 2025 announcement. Its design put ChatGPT inside the browsing experience rather than requiring users to copy web content into a separate chat.
According to OpenAI, ChatGPT could assist in the active browser window, help complete tasks, and use built-in memory so conversations could draw on prior chats and saved details. These were OpenAI’s product descriptions and intended behavior, not independent performance test results.
ChatGPT Atlas timeline

Is OpenAI’s AI browser still available?
No. OpenAI’s notices describe Atlas as deprecated and scheduled its shutdown for August 9, 2026. Treat Atlas as discontinued rather than as a browser you can newly download or use.
#1 Best Overall
OpenAI said browser-based agentic capabilities would move into ChatGPT and Codex. The available notices do not establish that those products reproduce every Atlas feature, nor do they specify complete feature parity, plan availability, platform coverage, or identical privacy controls.
What features did OpenAI document?
Atlas support materials covered several browser functions, including:
Rank #2
- Browsing and tab management
- Autofill and downloads
- Workspace switching
- Safe search
- Browser memories
- Privacy settings and site permissions
OpenAI also published browser release notes describing feature releases, improvements, and fixes. Those pages document the areas Atlas supported; they do not independently verify how reliably each feature worked or whether every feature remained usable until shutdown.
What should former Atlas users do?
OpenAI’s deprecation guidance focused on bookmarks. If you still have access to an Atlas installation or an exported bookmark file, use this path:
- Export your Atlas bookmarks before leaving the browser.
- Open the import-bookmarks tool in your replacement browser, such as Chrome.
- Select the exported bookmark file and confirm the import.
- Check folders and saved links after import.
This guidance covers bookmark migration only. The cited notice does not explain what happened to every other category of Atlas data, such as browser memories, settings, downloads, or workspace information.
What replaces Atlas?
OpenAI’s stated direction was to bring browser-based agentic capabilities into ChatGPT and Codex instead of maintaining Atlas as a separate browser. That is a product-strategy statement, not a promise that a single successor has the same interface or feature set.
Rank #4
Before relying on a successor for a specific workflow, verify its current availability, supported platform, subscription requirements, permissions, and privacy behavior. The official notices available here do not settle those details.

The headline describes a past event. OpenAI did release an AI-centered browser—ChatGPT Atlas—on October 21, 2025, then deprecated it and scheduled its shutdown for August 9, 2026. Former users were told to export bookmarks and import them into another browser, while OpenAI said related agentic browsing capabilities would move to ChatGPT and Codex.
