📌 Key Takeaways

- Available worldwide on macOS today, with Windows, iOS, and Android coming soon.
- Install and get started: See how to download Atlas and use it for free.
What ChatGPT Atlas Is
Atlas is a full browser where ChatGPT sits beside every page you open, ready to summarize, compare, and rewrite without copy-paste chores or switching apps.
“The browser with ChatGPT built in.” — OpenAI
The new-tab view combines chat and search, so links, images, videos, and news appear alongside conversational answers. It keeps navigation familiar with tabs, bookmarks, and autocomplete.

Privacy, Memory, And Control
You decide when ChatGPT can see a site, using an address-bar toggle that blocks page access when disabled. That prevents content capture and memory creation.
If you turn on browser memories, ChatGPT can remember helpful context, which you can review, archive, or delete at any time inside settings.
Agent Mode: What It Can and Cannot Do
Agent mode can navigate sites, open tabs, and complete tasks like planning trips or ordering groceries, all with visible steps you can monitor.
Limits are explicit: it cannot run code in the browser, download files, install extensions, or access other apps or your file system. It pauses on sensitive sites.
Availability And Plans
Atlas is available worldwide on macOS for Free, Plus, Pro, and Go accounts. Business has a beta, and Enterprise or Edu can be enabled by administrators.

Agent mode launches in preview for Plus, Pro, and Business users, with iterative reliability and latency improvements on the roadmap.
What’s Next For Atlas
OpenAI lists multi-profile support, developer tooling, and improved Apps SDK discovery as upcoming additions to the browser experience.
Website owners can use ARIA tags to help the agent operate more predictably on their sites inside Atlas. Release notes will update as features ship.
The ChatGPT Moment
ChatGPT is reported to have ~800 million weekly active users, a scale that could accelerate adoption of a browser-native assistant.
Chrome’s global desktop share is cited around ~72%, which sets a high competitive bar for any newcomer browser.
How To Download ChatGPT Atlas
Atlas is currently macOS-only, with other platforms planned, so install on a Mac to begin.
- Go to chatgpt.com/atlas and click Download for macOS.
- Open the installer, move ChatGPT Atlas to Applications, and launch it.
- Sign in to ChatGPT, then import bookmarks, passwords, and history from your current browser.
- Visit Settings to manage memories, training opt-in, incognito, and site visibility defaults.
- If eligible, enable agent mode (preview) under your Plus, Pro, or Business plan.
How To Use ChatGPT Atlas
Once installed, Atlas puts ChatGPT next to every page, so summarizing, planning, and shopping happen inside your normal browsing flow.
- Open the sidebar on any page, then ask ChatGPT to summarize, compare, or extract key points.
- Toggle page visibility in the address bar to allow or block ChatGPT’s view of the current site.
- Enable browser memories if you want persistent context, then review or delete entries in settings.
- Start agent mode from the toolbar, approve actions, and watch the sequence as tabs open and tasks complete.
- Use incognito to keep chats, browsing, and account activity unsaved and unlinked for that session.
Safety Notes Worth Knowing
OpenAI highlights red-teaming against hidden malicious instructions and the risk posture when agents act on logged-in sites. Users can run agents while logged out to reduce exposure.
Safeguards will evolve, and vulnerabilities will be patched, but the company warns that no defense is perfect as agent usage grows.
Conclusion
Atlas brings page-aware help, optional memory, and preview agents into a familiar browser, reducing friction between reading, deciding, and doing. It keeps controls visible and configurable.
If adoption matches ChatGPT’s existing scale, agentic browsing could become routine on macOS first, with Windows, iOS, and Android following later.
