Perplexity Comet: AI Browser Installation, Pricing & Security

👁 119 reads

Comet is Perplexity’s free browser built on Chromium, with an AI assistant embedded in every tab. It works on Windows, macOS, Android and iPhone, supports Chrome extensions, and with an upgrade to Pro or Max you get agents that execute tasks in the background. Below: how to install it, what it can do, how much the add-ons cost and what to watch out for. Everything about the search engine itself is in our Perplexity guide.

History in Five Dates

• July 9, 2025 - launch on Windows and macOS, only for Max subscribers at $200 per month.
• October 2, 2025 - Comet free for everyone, and for Max users Background Assistants.
• November 20, 2025 - Android version.
• March 18, 2026 - iPhone version, then multi-window support on iPad.
• August 2026 - US appeals court lifted the ban on Comet using the Amazon store. We covered this in our article Perplexity won against Amazon.

Installation Step by Step

1. Download Comet from perplexity.ai/comet (Windows, macOS) or from Google Play or App Store. Only install from these sources - the publisher is Perplexity AI.
2. Log in with your Perplexity account - then the assistant uses your plan’s limits and history syncs with the app.
3. Transfer bookmarks, passwords and extensions from Chrome - Comet is Chromium, so add-ons from Chrome Web Store work without changes.
4. The default search engine is Perplexity. If you prefer Google, you can change this in search settings just like in Chrome.
5. Open the assistant with a shortcut or icon in the toolbar and ask your first question about the open page, e.g. “Summarize this article in 5 points”.

What Comet Can Do

• Assistant with every tab - summarizes the page, answers questions about its content, translates, extracts data into a table.
• Work across multiple tabs - compare several offers, reviews or articles at once. Most practical example: five open pages with prices and a request for one comparison table.
• Voice mode - on Android you can talk to the assistant about all open tabs.
• Tasks in the browser - the assistant clicks, fills out forms, drafts emails, adds events to calendar. You can see what it’s doing at every step and stop it.
• Background Assistants (Max only) - several tasks in parallel from one panel, e.g. searching for cheap tickets while you work in another tab.
• Comet Plus - access to paid content from partners (including CNN, Condé Nast, Fortune, Los Angeles Times, Washington Post, Le Monde, Le Figaro). 80% of revenue goes to publishers, and Perplexity reserved a pool of $42.5 million at launch.

How Much Comet Costs

Plan details are in our articles How much Perplexity costs and Perplexity Pro: is it worth it.

Security: What to Watch Out For

A browser with an agent has access to everything you have access to: email, banking, shopping. This changes the risk.

• Prompt injection - a page can hide commands for the assistant in its content. In August 2025, LayerX described an attack called CometJacking that allowed data extraction through a crafted link. Perplexity first claimed it saw no threat, later announced the vulnerability was patched.
• Shopping and payments - we don’t let the agent finalize payments. Let it prepare the cart, but we click “Buy” ourselves.
• Separate profile - for work with the agent we use a profile without logged-in banking and main email.
• Data - content of pages you ask about goes to Perplexity servers. For company documents, the Enterprise version or local Portable Computer is better, described in our article Portable Computer on Windows.

Comet vs. Competition

We covered the end of Atlas in our article OpenAI closed Atlas, and the broader market picture in AI browsers instead of search engines. Our first impressions of Comet from 2025, still from the Max-only version, are in We tested Comet browser.

Is It Worth Switching to Comet

• Yes, if you already use Perplexity and often compare several pages at once. The assistant by the tab saves copying text to chat.
• Yes, on trial, if you have Chrome with a few extensions - you’ll transfer them in a minute and can return just as quickly.
• No, if the browser has access to company systems and IT doesn’t allow AI agents. Then stick with Chrome or Edge with the assistant disabled.

Frequently Asked Questions

Is Comet free?

Yes, since October 2, 2025 the browser is free on all systems. Paid are Comet Plus ($5 per month or included with Pro) and background assistants in the Max plan.

Does Comet work in other languages?

The assistant responds in multiple languages, and the app description in Google Play is translated. Pages and tabs work like in Chrome, because the engine is the same.

Do Chrome extensions work in Comet?

Yes. Comet is built on Chromium, so it installs add-ons from Chrome Web Store.

Is Comet secure?

As a browser, just as secure as Chrome, but the AI agent adds risk of hidden commands on pages. We don’t give it access to banking and we approve payments ourselves.
