Comet is Perplexity's AI-powered browser. It puts an assistant inside the browsing experience so you can ask questions about what is on screen, summarize pages, draft emails, build small artifacts, and delegate multi-step tasks across the web.
The assistant understands the page you are on, so you can ask follow-up questions and get answers grounded in what you are reading.
Delegate tasks like drafting replies, creating study plans, or building a simple website, with the assistant taking actions for you.
Comet runs on Mac, Windows, iOS, and Android, so your browsing and your assistant follow you across devices.
Perplexity's answer engine is built in, so research and web search stay inside the browser instead of a separate tab.
