At a glance
Perplexity Comet is a web browser with an AI assistant built into it. Instead of just showing pages, it can read what you are looking at, answer questions, summarize, fill forms, and even shop or book across sites for you. It is built on the same core as Chrome, and it is now free. Think of it as a browser that does tasks, not just a window to the web.
The web browser has barely changed in 20 years. Perplexity Comet is one of the first real attempts to rebuild it around AI, and in 2026 it went free for everyone. Here is the plain-English guide to what Comet is, what it does, and whether it is worth switching to.
What is the Perplexity Comet browser?
Comet is a web browser made by Perplexity, the company behind the AI answer engine. It looks and works like a normal browser, built on the same open-source core as Google Chrome, but it has an AI assistant living in a sidebar that can see your tabs and help with what you are doing.

How is Comet different from Chrome?
Chrome shows you pages and leaves the work to you. Comet adds an assistant that works across those pages. Ask it to compare three products you have open, summarize a long article, pull the key points from a report, or fill in a form, and it does the steps rather than handing you links. It is the difference between a tool that displays the web and one that acts on it.
What can Comet do?
- Summarize the page or video you are on
- Answer questions using your open tabs for context
- Research a topic and pull together the findings
- Fill out forms and help with shopping or booking steps
- Work by voice, hands-free
Is the Perplexity Comet browser free?
Yes. Comet launched in 2025 as a pricey subscription, but through 2026 Perplexity made it free across Mac, Windows, iPhone, and Android. You can use it free with a Perplexity account, and the paid Pro and Max plans add higher limits and extra features. For where those sit, see our Perplexity pricing guide.
Is Comet safe to use?
Helpful, but keep a hand on the wheel. Because Comet can act for you, filling forms or moving through a checkout, review what it is about to do before you let it, especially with payments or personal details. It also sees your browsing to be useful, so check the privacy settings and decide what you are comfortable sharing. Treat it as an assistant you supervise, not an autopilot.
How does Comet compare to ChatGPT Atlas?
They are the two big AI browsers of 2026, and the idea is the same: an assistant built into the browser that can act on the pages you visit. Comet comes from Perplexity with its research strength; ChatGPT Atlas comes from OpenAI. Both are worth trying if the idea appeals.

Common questions about Perplexity Comet
Does Comet replace the Chrome browser?
It can. Comet is built on the same core as Chrome and can import your bookmarks and settings, so it works as a full everyday browser with AI added on top.
Do you need a Perplexity account?
Yes, a free Perplexity account signs you in. The browser itself is free, with optional paid plans for heavier use.
Can Comet really shop or book for me?
It can help with the steps, like filling carts and forms, but review anything involving payment before you confirm. It is an assistant, not a fully hands-off agent yet.
Is Comet private?
It needs to see your browsing to help, so review the privacy settings and limit what you share on sensitive sites. Treat it like any tool with access to your activity.
