Comet
Perplexity's AI-first browser.
Comet is Perplexity's browser, built around the idea that the assistant should already know what you are looking at. Instead of pasting a page into a chat window, you ask about the tab you have open, and the agent can act across tabs — compare a set of pricing pages, pull the shared claims out of six articles, fill in a repetitive form. The trade-off is the usual one for agentic browsing: it is genuinely faster on multi-tab research, and it needs supervision the moment a task involves acting on your accounts.
Best for
- Research sessions that span many tabs
- Summarising and comparing pages in place
- Delegating repetitive browsing chores
Key features
- Assistant with the current page and open tabs as context
- Carries out multi-step tasks in the browser
- Search built in rather than bolted on
Why it matters
Putting the agent inside the browser removes the copy-paste step between what you are reading and what you are asking about.
