Question 1

ChatGPT Atlas vs Comet Browser — Which should I choose?

Accepted Answer

Both Atlas (OpenAI) and Comet (Perplexity AI) represent a new generation of "agentic browsers," but they emphasize different strengths:[^4][^5][^6]  | Feature | ChatGPT Atlas | Perplexity Comet | |---------|---------------|------------------| | Core AI Integration | ChatGPT | Perplexity Search | | Ideal For | Structured tasks and workflow automation (e.g., research, scheduling) | Real-time information retrieval and exploration | | OS Support | macOS (Windows/iOS coming soon) | Windows, macOS, web | | Agent Mode | Available for paid ChatGPT tiers | Built-in for all users | | Memory System | Optional, user-controlled browser memories | Session-based contextual recall | | Pricing | Free with premium upgrades | Fully free currently | | Strength | Tight integration with ChatGPT ecosystem | Seamless search and real-time updates |  Choose Atlas if you already rely heavily on ChatGPT for writing, codifying, and planning—its integration is excellent for creation workflows and productivity automation. Choose Comet if you prefer fast, source-rich answers, real-time web access, and an exploration-first experience.[^5][^6][^4]

Question 2

Can I use ChatGPT Atlas with Perplexity AI?

Accepted Answer

Technically, yes—you can open Perplexity AI inside Atlas just like any other website, since Atlas is a Chromium-based browser. However, the integration between them is not native: ChatGPT and Comet run on separate AI ecosystems. This means:[^3][^2]  - You can use Perplexity AI's website (www.perplexity.ai) inside Atlas to perform searches. - But ChatGPT Atlas's Agent Mode and Perplexity's Comet agents do not interoperate or share context or memory. - Features like ChatGPT memory, agent automations, and model calls stay within Atlas; Perplexity sessions stay sandboxed in their own site environment.[^2][^3]  In short, you can use them together in the same workflow, but not as interconnected systems.
