Comet is Perplexity's Chromium-based browser, free to download on Mac, Windows, iOS and Android, with Perplexity as its default search engine, a built-in ad blocker and an assistant beside every page. The free version does not include the agent that clicks, fills in forms and completes tasks on websites: Perplexity's plan table lists browser agent queries from Pro, at $20 a month or $200 a year, with higher limits on Max at $200 a month. Browsing data stays on your device by default and is shared with Perplexity only when you ask something that needs personal context. There is no Linux version.

Perplexity released Comet to everyone, for free, on October 2, 2025, after three months as an invite-only browser that began with a limited launch on July 9. A year on, it runs on Mac and Windows as well as iPhone and Android, with Perplexity as the search engine and an assistant beside every page. What the free download leaves out is the part most people want. That's the agent, the bit that clicks through websites and finishes errands for you.
Perplexity's plan comparison, updated in September 2026, lists "Browser Agent (Comet Assistant)" queries as not included on the free plan. Pro, at $20 a month or $200 a year, gets a monthly allowance sized for average use. Max, at $200 a month, gets more. Only the business plans put a number on it: 80 agent queries a month on Enterprise Pro, 800 on Enterprise Max.

From Perplexity's help center plan table and its Comet Plus announcement, checked October 2, 2026. The iPhone app sells the same Pro and Max plans at $20 and $200.

So for a free user, Comet is mostly a fast Chromium browser with Perplexity's cited answers in the address bar and a strong ad blocker. For a Pro subscriber, Comet is the place where the subscription does the most.
Perplexity draws a clear line between the two. The assistant lives in a side panel. It summarizes the page you're on and answers questions about it, or about any tab you mention with @. It can translate, pull out dates, or draft a reply from what's on screen. Alt+A opens it and Alt+S summarizes the page. Comet's memory also recalls your regular searches, so you can pick up where you left off.
The agent goes further. It clicks buttons and fills in forms on its own. Connect Gmail or your calendar and it can schedule meetings or send email for you. Perplexity's own examples run from unsubscribing from newsletters to booking travel. Results depend on the site. A login screen or a payment step can stall a task and hand it back to you, and the most common complaint is that it gets confused when it tracks too many tabs.
Comet's privacy model is better than many people assume. By default, your browsing data stays on your device. That includes the sites you visit, your searches and your cookies. Nothing personal goes to Perplexity until you ask what it calls a personal search, meaning a request that needs your context, like organizing your inbox. Then it uses the open tab and relevant history, and page content such as email text may be processed on Perplexity's servers. Passwords and card numbers stay in your operating system's secure vault. Connecting Gmail or a calendar is opt-in, and you can wipe your history at any time in Comet's privacy settings. Perplexity says it does not and will not sell your data.
The risk that remains belongs to every agentic browser. A web page can hide instructions meant for the AI instead of for you. It's called prompt injection, and an agent that's signed in to your accounts makes a tempting target. Keep the agent away from banking, watch what it does on sites where you're logged in, and confirm every purchase yourself.
Comet is built on Chromium, so Chrome extensions work. Setup brings over your extensions and bookmarks in one step, and Settings, then Default browser, makes it your main browser. The ad blocker is a decent reason to switch on its own. According to the iPhone app's listing, it also hides empty ad slots and gets past "disable your ad blocker" walls. Linux users are left out, with no version and no date.
Companies have their own route. Comet for Enterprise, added in March 2026, lets IT teams deploy the browser silently and manage it centrally.
Comet Plus is Perplexity's response to the charge that AI search takes traffic without paying for it. It costs $5 a month on its own and comes with Pro and Max. Perplexity announced it in August 2025 and says the money goes to participating publishers, minus a small share for compute. Payouts depend on human visits, citations in answers and actions taken by agents.
The agent's shopping has drawn the opposite reaction. Amazon sued Perplexity in November 2025 over Comet's automated purchases on its store, and a judge later blocked the agent from shopping on Amazon. Whatever the outcome, agent shopping works only where retailers allow it.
If you already pay for Perplexity Pro, Comet is the browser to try first, because the agent is part of what you pay for. If you don't, Comet is still a good free browser, but the AI features that set it apart sit behind the subscription. Dia is free on the Mac with its assistant included. Brave offers the free Leo assistant everywhere. And ChatGPT users may not need another browser at all, because the ChatGPT desktop app took over the browsing that the closed Atlas used to do. The best AI browsers guide lines them up by price and privacy.
Not to browse. Comet is free to download and use with Perplexity search and its ad blocker, but Perplexity's plan comparison lists browser agent queries, where the Comet Assistant acts on websites for you, as unavailable on the free plan. Pro, at $20 a month or $200 a year, includes a monthly allowance for average use, and Max at $200 a month a larger one.
Comet runs on Mac, Windows, iOS and Android. There is no Linux version as of October 2026; Perplexity's FAQ only says that more platforms will arrive.
No. Comet is made by Perplexity AI, a US company based in San Francisco. Its co-founder and CEO, Aravind Srinivas, was born in India, which is probably where the question comes from.
Yes. Comet has a built-in ad blocker, and its App Store listing says it also hides leftover ad slots and gets past pages that ask you to turn ad blocking off. Since it is built on Chromium, Chrome extensions work too.
Perplexity stores browsing data on your device by default, uses it only when you ask something that needs personal context, keeps passwords and cards in your operating system's secure vault and says it does not sell data. The larger risk is the agent: like any AI browser, it can be misled by instructions hidden in web pages, so supervise it on signed-in sites and confirm payments yourself.
A $5-a-month subscription, included with Perplexity Pro and Max, that gives you and your assistant access to content from participating publishers. Perplexity says it passes the revenue to publishers, minus a small share for compute, split by human visits, citations in answers and actions taken by agents.
