“My browser could run my web errands for me”

Anyone who spends their day in their browser: comparing offers across several tabs, summarizing long articles, filling in forms, preparing a purchase or an appointment. If you juggle ten tabs and copy-paste information from one site to another, this profile is for you.

Comet (perplexity.ai/comet), Perplexity's browser: a full Chromium-based browser, compatible with Chrome extensions, with an AI assistant built into every tab. It summarizes your pages, compares information across your tabs and prepares your web errands in several steps.

How it works

Trigger: You open a web page or juggle several tabs — Comet's assistant summarizes the page, compares information across your tabs or prepares the form for you, and you get answers and errands prepared in your browser, to check before confirming.

Step-by-step setup

Download Comet for free (Windows, macOS, iOS, Android) and install it like any browser.
Open your usual sites: the Comet assistant is present in the sidebar of every tab.
Ask it in plain language: “summarize this page”, “compare these three offers across my tabs”, “prepare this form”.
For multi-step tasks (research + comparison + cart), describe the final goal and let it browse — then check each step before confirming.
Start with low-stakes tasks (summaries, comparisons) before trusting it with errands on your logged-in accounts.

⚠️ Guardrails: An agentic browser sees your pages and can click in your logged-in sessions — that's its strength and its risk. Never let it finalize a payment alone: check the cart and confirm yourself. Avoid sensitive sites (banking, critical accounts) until you've tested its behavior, and beware of pages that give it detoured instructions (“prompt injection attacks” documented on this type of tool in 2025): if a page tells it to do something other than your request, stop it. You can also pause it or use it in private browsing for sensitive searches.

Its particular angle

Like every general-purpose assistant, it can chat, write, summarize, translate and help with code. What sets it apart: it's a browser: it acts in the web pages you visit, as you browse.

Frequently asked questions

Is Comet free?

Yes. The browser and the basic assistant have been free for everyone since October 2, 2025 (official Perplexity announcement). The Pro ($20/month) and Max ($200/month) plans raise the caps and unlock advanced agentic tasks.

Does Comet replace Chrome?

Yes, it's a full browser based on Chromium: tabs, bookmarks, Chrome extensions. The difference is the AI assistant built into every tab.

What can the Comet assistant do?

Summarize a page, compare information across several tabs, draft text, fill in forms, prepare a purchase or a search — in multiple steps, within your open tabs.

Is it risky to let an agent click around in my browser?

Yes, if you let it run unsupervised: it acts within your signed-in sessions. Don't hand it a final payment or a sensitive site without checking, and stop it if a page tries to divert it from your request.
