How to Use ChatGPT Atlas in 2026: Step-by-Step Guide
OpenAI's standalone AI browser, discontinued August 9, 2026 — its agentic browsing features were folded into the ChatGPT desktop app, a ChatGPT Chrome extension, and Codex.
ChatGPT Atlas was OpenAI's dedicated web browser, launched October 21, 2025 as a macOS-only app built around ChatGPT as a persistent sidebar and agentic browsing layer.
Discontinued August 9, 2026
OpenAI announced on July 9, 2026 that it was discontinuing Atlas as a standalone browser, switching it off on August 9, 2026 — 292 days after launch. Rather than keep a separate browser alive, OpenAI folded its browser-based agentic capabilities into two existing surfaces:
- ChatGPT desktop app — gained an upgraded browser mode with multi-tab support, file downloads, improved navigation, and account login handling.
- A ChatGPT extension for Google Chrome — brings the same in-page assistant and agentic actions to a user's existing browser instead of a dedicated one.
Codex also picked up related agentic-browsing capability. Atlas never shipped on Windows, iOS, or Android despite those being promised at launch, which limited its addressable audience to macOS users for its entire life.
What to use instead
The functionality Atlas offered (in-page ChatGPT sidebar, agentic form-filling and task completion) is now available directly inside the ChatGPT desktop app or via the ChatGPT Chrome extension — see openai.com/chatgpt.
Positioning (historical)
Atlas competed in the same "AI-native browser" category as Perplexity Comet, Dia, and Opera Neon before its shutdown.
What You'll Need
- A ChatGPT Atlas account (starting from Discontinued August 9, 2026 — folded into ChatGPT desktop app, Chrome extension, and Codex)

- Payment method for paid features
Getting Started
Create Your Account
Visit https://openai.com/chatgpt and sign up for a discontinued account. You'll need an email address to register.
Start Your First Conversation
Once logged in, you'll see the main chat interface. Type a question or task in the input box and press Enter. ChatGPT Atlas supports ai-browser, agent-mode, summarization, form-filling — start with a simple text prompt to get familiar.
Pro Tips
- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show ChatGPT Atlas what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
