ChatGPT Atlas
OpenAI
Deprecated OpenAI browser scheduled to shut down August 9, 2026 as agentic browsing moves into ChatGPT.
Overview
Freshness note: This migration profile is a point-in-time snapshot last verified on July 10, 2026.
ChatGPT Atlas was OpenAI’s macOS browser with ChatGPT and agent mode built into the browsing workflow. OpenAI deprecated Atlas on July 9, 2026 and scheduled it to stop working on August 9, 2026 as browser-based agentic capabilities move into ChatGPT and Codex.
Do not start a new Atlas rollout. Existing users should use the remaining wind-down period to export or save browser data and move workflows to the new ChatGPT desktop app, the ChatGPT Chrome extension or sidebar where available, or another supported browser.
Key Features
Atlas combined a conventional browser, an Ask ChatGPT sidebar, browser memories, page visibility controls, and an agent mode that could research and act across websites. It also supported separate browser profiles, bookmarks, passwords, history import, and macOS browsing workflows.
The replacement direction is not a one-click migration. OpenAI is bringing multiple tabs, downloads, improved navigation, account login support, and browser-agent capabilities into the ChatGPT desktop app. The built-in browser uses a separate profile, while the Chrome extension is the better route when ChatGPT needs an existing Chrome tab or signed-in profile.
Strengths
Atlas helped validate the usefulness of keeping conversational assistance beside the page being read or operated. Its research, summarization, and lightweight agent workflows reduced tab switching and copy-paste friction for users already centered on ChatGPT.
Those strengths now matter mainly as product history because OpenAI is transferring the browser-agent direction into supported ChatGPT surfaces.
Limitations
The decisive limitation is retirement. After August 9, Atlas may no longer open, browse, or support browser-based agent workflows, and discontinued browsers may stop receiving security updates.
Atlas bookmarks, open tabs, and browser history do not transfer automatically. ChatGPT conversations are stored separately and remain available subject to the user’s plan and workspace, but browser data requires manual action. Cookies and session exports should be treated as sensitive credentials.
Practical Tips
Export bookmarks to HTML, save important tab URLs, and capture any history you need before August 9. Test the exported bookmark file before deleting Atlas. Do not send cookie or session files to another person or an untrusted service.
Use the ChatGPT desktop app for deeper agentic browser work. Use the Chrome extension or sidebar when the workflow depends on an existing Chrome profile. Update internal onboarding, support, and security documentation so new users are not directed toward Atlas.
Verdict
ChatGPT Atlas is now a migration-only reference. Its browser-agent ideas continue inside ChatGPT, but the Atlas application itself should be retired from active workflows before August 9, 2026.
