Comet
Perplexity's Chromium-based browser with an assistant in every new tab that researches, handles email and runs agentic tasks on the pages you are already on.
Updated 2026-08-02
Yes, within limits. Comet runs a free tier with paid plans above it.
Listed pricing: Free to download; Perplexity Max at $200/mo unlocks the highest limits.
Overview
Comet is Perplexity's browser. It is built on Chromium, which means most extensions from the Chrome Web Store work, and the import flow carries over bookmarks, passwords, cookies, history and extensions from whatever you were using before. Perplexity supports it on Windows 10 and 11, in both x64 and ARM64 builds, and on macOS 13 Ventura and later on Intel and Apple Silicon, with a mobile version available separately.
The reason to switch is the assistant. Perplexity puts a Comet Assistant on every new tab, and its framing is that the assistant browses with you rather than for you: research, meetings, code, shopping. Because it lives in the browser, it can see and act on the page already open, which is the structural advantage over a chatbot in another window. For Perplexity Max subscribers there are Background Assistants, which launch many agentic tasks in parallel and collect confirmations and follow-ups on a single page, and an Email Assistant.
My read: Comet has no price of its own, and that is the confusing part. The browser is a free download. What you actually get depends on the Perplexity plan behind the account, and Perplexity publishes the browser-agent allowance only in relative terms, describing Max subscribers as receiving the highest weekly limit on browser agent queries across all tiers without saying what that limit is. Max is listed at $200 a month or $2,000 a year. So the decision is not whether to buy Comet, it is whether the browser is enough of a reason to move up a Perplexity tier. Worth noting on sourcing: perplexity.ai blocks automated fetches, so the details here come from Perplexity's own help centre and announcement pages rather than a direct read of the marketing page.
Is Comet free?
Yes, within limits. Comet runs a free tier with paid plans above it.
What the free tier covers: Yes. The browser is a free download and works without a paid Perplexity plan. The agentic features and the higher query limits are what a subscription buys.
Listed pricing: Free to download; Perplexity Max at $200/mo unlocks the highest limits.

Is Comet worth it?
Worth it for People who want an assistant that acts on the page in front of them, and who would rather switch browsers than add another tab to their workflow.
You can test that on the free tier before paying anything. The recorded trade-offs are listed below, and any one of them can settle the question on its own.

Worth it if
The strengths recorded against this entry.
- Assistant operates on the page you are already viewing instead of in a separate window with no context
- Chromium base keeps most Chrome extensions working, which removes the usual dealbreaker when switching browsers
- Import carries bookmarks, passwords, cookies, history and extensions across in one step
- Free to download with no subscription required to start using it
- Background Assistants give paying users parallel agentic tasks with confirmations gathered in one place
Not worth it if
Any one of these blocks your use case.
- Browser-agent limits are published only as relative claims, so no tier states how many agent queries you actually get
- The features most people want the browser for, Background Assistants and Email Assistant, sit behind the $200/mo Max tier
- Switching browsers is a bigger commitment than installing an extension, and profile migration is never fully clean
- An assistant with access to your logged-in sessions is a meaningful trust decision that a chat window in another tab does not require
What sets Comet apart
- The assistant sits in the browser itself rather than in a separate app or tab
- Chromium base means most Chrome Web Store extensions carry over
- Import brings bookmarks, passwords, cookies, history and extensions across from an existing browser
- Background Assistants run agentic tasks in parallel for Perplexity Max subscribers
- Free to download, with capability tied to whichever Perplexity plan the account is on
Key features
Comet Assistant on every new tab
Perplexity's description is that every new tab has an assistant ready to answer a question or take an action, covering research, meetings, code and e-commerce. Being in the browser is what lets it work on the page already loaded.

Background Assistants
Perplexity Max subscribers can launch many agentic tasks in parallel and manage confirmations and follow-ups from a single Background Assistants page inside Comet.
