Comet

About Comet

Comet is Perplexity's AI-first browser, free on Windows, Mac, Android and iOS, and it sets out to change how we consume information. Instead of a list of blue links, Comet uses AI to synthesize answers, presenting a "knowledge-first" interface where the browser actively helps you understand topics rather than just displaying pages.

It enables a conversational research flow. You can ask follow-up questions, compare sources side-by-side, and see citations clearly marked. The goal is to reduce the "tab sprawl" that comes with researching complex topics by bringing the answer to the surface.

Underneath it is a full Chromium browser that handles everyday tasks like banking and shopping, but it is at its best for students, researchers, and anyone who uses the web primarily to learn, where it offers a clear look at where AI-mediated browsing is heading.

Frequently asked questions

Do I need a Perplexity subscription to use Comet?

Comet offers basic features for free, but some advanced AI capabilities may require a Perplexity Pro subscription. The core browsing experience and basic AI-powered search work without a paid plan.

Can Comet replace my main browser?

It can. Comet is built on Chromium, installs Chrome Web Store extensions, and blocks ads and fingerprinting scripts by default, so the everyday basics are covered. Its real focus is research, though; if you rarely use its AI features, a conventional browser gives you less to learn.

How does Comet differ from just using Perplexity in Chrome?

Comet integrates AI directly into the browsing experience rather than keeping it in a separate tab. You can get inline answers, compare sources side-by-side, and maintain conversational context as you browse—something a standalone Perplexity tab can't do.
