ChatGPT ATLAS vs Comet: Which AI Browser Leads the Pack in 2025?
The race of AI-powered web browsers has reached a thrilling new phase — and at the center of it are two heavyweights: ChatGPT ATLAS and Comet (by Perplexity). In this blog we’ll dive deep into ChatGPT ATLAS vs Comet, exploring features, performance, privacy, limitations, and what each offers to users in 2025.
What Are ChatGPT ATLAS and Comet?
ChatGPT ATLAS is the new AI browser from OpenAI, built on a Chromium base and deeply integrated with the ChatGPT chatbot. Wikipedia+1 It is designed to transform browsing into a collaborative, agent-driven experience.
Comet, meanwhile, is Perplexity’s answer to the AI browser trend: a tool that offers AI-powered search, agentic actions (for paid tiers), and knowledge synthesis built into the browsing workflow.
When comparing ChatGPT ATLAS vs Comet, we’re essentially comparing two visions of the future of the internet: one built around ChatGPT’s ecosystem, the other oriented toward flexible knowledge-first browsing.
Key Features: ChatGPT ATLAS vs Comet
ChatGPT ATLAS Features
- Agent mode: automates tasks like shopping carts or reservations.
- Memory: browser “remembers” pages, tasks, and user context to surface suggestions.
- Integrated “Ask ChatGPT” button for each webpage, real-time summarization and edits.
- Built on Chromium so bookmarks, extensions, and logins carry over.
- Currently available on macOS; Windows, iOS, Android support coming.
Comet Features
- AI browser centring knowledge synthesis, built-in chat and browsing tasks.
- Supports multi-step workflows and automations for power users.
- Integration with trip planning, shopping, email tasks in AI agent model.
- Offers a “discover” feed of news and AI-generated summaries (in some versions).

Usability & Performance: How They Compare
In head-to-head usage, ChatGPT ATLAS vs Comet shows some interesting trade-offs:
- In a test, Atlas loaded smoothly and was stable. Still, there were delays when the AI processed complex queries.
- Comet currently tends to handle multi-tab research and automations more efficiently, according to some reviewers.
- Atlas brings strong benefits if you’re already entrenched in the ChatGPT ecosystem; but it still lacks some power-user features that Comet provides.
- For general browsing, both browsers deliver a fresh experience; for highly advanced workflows, Comet slightly leads at present.
Privacy & Security Considerations
When evaluating ChatGPT ATLAS vs Comet, this is where things get complex:
- Atlas retains “memory” of tasks and pages; while you can delete memories or opt out, its depth of tracking raises questions.
- Atlas’s agent mode gives the AI broad access, which may pose risk if credentials or sensitive sites are involved. Reviewers urge caution.
- With Comet, researchers discovered a vulnerability dubbed “CometJacking,” in which hidden prompts in URLs could manipulate the AI to extract personal data.
- Both browsers, as part of the broader AI-browser wave, inherit new risk vectors.
- In short: convenience vs. caution — whichever browser you pick, you should treat agentic features responsibly and avoid using critical activities unless you trust the setup.
Feature Comparison: ChatGPT ATLAS vs Comet
| Feature | ChatGPT ATLAS | Comet |
|---|---|---|
| Agent mode | Yes — preview for paid | Yes — mature workflows |
| Memory / context tracking | Yes — built-in memory | More limited or controlled |
| Multi-tab research | Present but early | Stronger support |
| Cross-platform availability | Mac only (initial) | More mature on multiple platforms |
| Workflow power users | Good for ChatGPT users | Better for power workflows |
| Privacy risk | Higher (memory, agent) | Known vulnerabilities |
Which Should You Choose?
If you already use ChatGPT frequently and value seamless integration, the ChatGPT ATLAS browser may be your preferred pick. It offers the tightest link between browsing and the ChatGPT assistant experience.
If you’re a researcher, knowledge worker or someone who deals heavily with tab management, context pulling, and complex workflows — Comet may edge out as the more flexible tool right now.
Selecting between ChatGPT ATLAS vs Comet therefore comes down to:
- Existing ecosystem: Are you already using ChatGPT heavily?
- Workflow needs: Do you need power user features, multi-tab context, advanced automations?
- Privacy stance: Are you comfortable with AI browser memory and agent features?
- Platform support: Are you on Mac only or need Windows/Android support right now?
The Future of AI Browsers in 2025 & Beyond
The broader context: AI-powered web browsers are quickly becoming a defining platform shift. Browsers are no longer just windows to the web — they are collaborative AI assistants. As flagged in this article, when comparing ChatGPT ATLAS vs Comet, we’re witnessing the dawn of that shift.
Expect to see:
- More advanced agent modes — scheduling, shopping, email automation, deep workflows.
- Cross-platform expansion: Atlas moving onto Windows, Android; Comet similarly.
- Increased scrutiny: privacy, data collection, and prompt-injection vulnerabilities will be front-of-mind.
- Deeper integration with other tools — cloud docs, email, voice assistants, IoT.
- UI and workflow innovations: multi-tab contexts, skills galleries, one-phrase macros.
