Comet

Short Answer

Comet is Perplexity’s attempt to build an AI-first browser, one where research and AI assistance are built into the browsing experience rather than bolted on as extensions. It’s designed for people who spend significant time researching and want AI woven into how they navigate the web.

What Comet Is Best For

• Research-heavy workflows: get AI summaries and synthesis as you browse
• Perplexity users: extends the Perplexity experience directly into the browser
• Reducing tab switching: access AI assistance without leaving the page you’re on
• Summarizing pages: get instant summaries of articles and documents while reading

The AI Browser Concept

AI browsers like Comet, Atlas, and Dia represent a new category: instead of adding AI as a browser extension, they build AI capabilities into the browser’s core, closer to how search is built into Chrome’s address bar, but for AI assistance across your whole browsing session.

Honest Limitations

• Newer product: still developing; features and availability may be limited
• Perplexity-centric: best for people already in the Perplexity ecosystem
• Browser switching cost: moving from Chrome/Safari requires rebuilding habits and bookmarks

Alternatives Worth Knowing

• Atlas, OpenAI’s competing AI browser with ChatGPT integration
• Dia, AI-first browser from a different team
• Perplexity, Perplexity’s main product if you don’t need the full browser
