Perplexity Comet Agentic AI Browser

Turn the browser from a viewer into an executor: Comet is Perplexity's Chromium-based AI-first browser with the assistant built into the browsing experience, able to summarise long pages across tabs, tidy tabs, draft and send email, compare products and fill forms — free to download

Tool Interface

Interactive tool will be available soon

Features

  • ✓ AI-first rather than bolt-on: instead of an extension on a normal browser, Perplexity's AI search and assistant are built directly into the browser interface
  • ✓ From summarising to doing: beyond reading summaries it can organise tabs, compare products, book travel and fill forms, chaining multi-step web tasks for you
  • ✓ Chromium-based: keeps compatibility with the existing web ecosystem and extension habits, so switching costs far less than moving to a proprietary engine
  • ✓ Broad platform coverage: Windows, macOS, Android, iOS and Vision Pro all have builds, so the same assistant works on mobile and desktop
  • ✓ Free since October 2025: the worldwide free download removed the top-tier subscription requirement, greatly lowering the barrier to trying it

How to Use

  1. Download the build for your OS from the official site and import your existing bookmarks and passwords; try it first with a non-critical account to see what data it can reach
  2. Start with low-risk tasks: have it summarise long articles, compare two or three products or tidy a pile of tabs, and watch how stable it is when jumping across tabs
  3. Codify repetitive flows: hand it the daily loops such as price checks, form filling or reading digests, but keep manual confirmation for payments and account changes
  4. Isolate sensitive work: the assistant runs inside your real browser session and can see logins and extensions, so use a separate browser profile or stay logged out for high-sensitivity sites

FAQ

What is Perplexity Comet?

Comet is Perplexity's AI browser, built on Chromium and integrated with Perplexity's AI-assisted search and assistant. It launched for Windows and macOS on 9 July 2025, expanded to Android on 20 November 2025 and iOS on 18 March 2026, and has been free to download worldwide since October 2025. The official site is https://www.perplexity.ai/comet and background is at https://en.wikipedia.org/wiki/Comet_(browser)

How is it different from adding an AI extension to Chrome?

It comes down to whether the assistant is a first-class citizen. Extensions are constrained by the host browser's APIs and typically act only on the current page. Comet builds AI search and the assistant directly into the browser interface, which is why it can read across tabs, organise tabs, draft email, compare and shop, and fill forms. Because it is Chromium-based, web compatibility and extension ecosystem switching costs stay manageable. See https://www.perplexity.ai/comet and https://en.wikipedia.org/wiki/Comet_(browser)

Does it still require payment?

No dedicated top-tier subscription is needed any more. Comet was initially limited in July 2025 to subscribers of Perplexity's most expensive tier, then announced as a free worldwide download in October 2025. Free availability does not mean unlimited models and quota, so confirm current capability limits on the official site: https://www.perplexity.ai/comet — see also https://www.cnbc.com/2025/10/02/perplexity-ai-comet-browser-free-.html

Is it safe to let it shop for me?

Separate information tasks from authorised actions. Summarising, price comparing and research are low risk because mistakes are visible to you. Placing orders, changing account settings or sending email have side effects, so keep a human confirmation on the final step. The core reason is that it runs inside your real browser session and inherits your logged-in state, so manipulation by page content carries a wider blast radius than an agent in an isolated sandbox.

Who benefits most from it?

People who move a lot of information around in a browser every day: researchers and marketers synthesising many sources, procurement and operations staff comparing products constantly, and anyone turning web pages into structured notes. What these tasks share is many steps, high repetition and happening inside the browser. Conversely, if your work lives in an IDE or a spreadsheet, the payoff is much smaller.
