Atlas and Comet: ตัวเลือกไหนคือ AI Browser ที่ดีกว่า?

As Artificial Intelligence (AI) technology rapidly develops, web browsers are also starting to incorporate AI to enhance their performance. Two names that are gaining attention are ChatGPT Atlas from OpenAI and Comet from Perplexity AI. Both offer a new concept of web browsing that combines intelligent assistants, automated memory, automation, and built-in help systems. But when it comes to choosing which one is better, we need to understand the differences, strengths, and trade-offs of each.

Overview of each browser 

ChatGPT Atlas 

Atlas is a browser designed with ChatGPT at its center, deeply integrating into the web experience. Users can open the ChatGPT sidebar to summarize content, compare products, analyze web pages, or even delegate tasks to an agent. 

Key Features: 

• “Browser Memories” feature that helps the assistant remember the context of your browsing and recall it later. 
• Agent Mode (Preview version for Plus/Pro/Business users) that allows ChatGPT to interact with websites, such as researching information or helping with purchasing products. 
• Focus on security and user control: Choose which websites the assistant can see, turn memory mode on or off, and use Incognito mode. 
• Currently only macOS is supported, with Windows, iOS and Android versions under development. 

Comet 

Comet from Perplexity AI is also an AI-powered browser, launching in early 2025 and built on Chromium, designed to embed intelligent assistants deeply into the browsing experience. 

Key Features: 

• “Comet Assistant” that can summarize web pages, understand their context and perform actions such as booking travel tickets or searching for deals. 
• It was originally available to paid users but has since expanded to be more accessible to the general public. 
• Focus on productivity and exploratory browsing — Reduce tab switching, increase automation for common online tasks. 

Comparison table: Atlas vs Comet 

Which one should I choose (and why)? 

Choose Atlas if you: 

• Already using ChatGPT or products from OpenAI and want a seamless integration? 
• We need a contextual memory system that allows AI to remember and continue executing from the same point. 
• Prioritize control over personal data and what AI can access 
• Using macOS and waiting for updates on other platforms 

Choose Comet if you: 

• Want a browser with an AI assistant that can automate tasks across multiple websites? 
• Love the browsing experience that emphasizes performance and continuous work. 
• Accept the limitations of early software in exchange for cutting-edge features. 

Considerations and trade-offs 

• Security and Privacy: AI Browsers Raise New Risks Atlas prioritizes user data control, while Comet has some concerns about data access.
• Platform availability: Both are still in their early stages, some features are not yet complete. 
• Complexity of the task: Both agent modes are not yet able to handle all complex processes. 
• Ecosystem dependence: The choice may depend primarily on whether you are using ChatGPT or Perplexity. 

Summary 

Both Atlas and Comet are important steps in the era of “AI-native browsing,” where browsers are no longer just browsing tools but intelligent assistants working with you. If you had to choose right now, ChatGPT might have a slight edge, especially for users already in ChatGPT's ecosystem, due to its superior memory and information control features.

But on the other hand, Comet is an equally interesting option if you want a browser that's proactive and fully automated.

Ultimately, the choice comes down to your preferences — whether you want to integrate with your favorite AI assistant or choose a browser that's fully capable of handling tasks for you. Both reflect a new direction for the future of browsing, where AI isn't just an add-on, but rather the "heart" of the browser.
