The official Perplexity download for Windows 11 and Windows 10 is a free app from Perplexity AI on the Microsoft Store. On a Mac, you install Perplexity as a Safari web app that opens from the Dock.
The app answers questions with cited sources, takes voice questions and keeps your threads in a Library. It works with a free account, and Perplexity Pro is an optional paid upgrade.
Below are the official links, Store and winget install steps, the Mac setup, the difference between Perplexity and Comet, and fixes for an install that fails.
Which Perplexity download do you need?
Match your device to a row. Every route signs in to the same Perplexity account, so your threads follow you.
| Your device | What to get | Download size |
|---|---|---|
| Windows 10 version 1809 or later, or Windows 11, Intel or AMD | Perplexity on the Microsoft Store | 244.9 MB (x64 package) |
| Windows 11 on an ARM64 laptop (Snapdragon) | Perplexity on the Microsoft Store | 237.2 MB (ARM64 package) |
| Mac on macOS Sonoma 14 or later | perplexity.ai in Safari, then Add to Dock | Nothing to download |
| iPhone or iPad on iOS 18 or later | Perplexity on the App Store | 181.7 MB |
| Android phone or tablet | Perplexity on Google Play | Sized by Google Play for your device |
| A shared or locked-down computer | Perplexity in the browser | Nothing to download |
The Store picks the x64 or ARM64 package on its own. You never choose the architecture by hand.

Which Perplexity download do you need for your Mac?
Safari on macOS Sonoma turns any site into a Dock app. Perplexity then opens in its own window, without browser tabs or toolbars.
| Your Mac | What to do | Where |
|---|---|---|
| macOS Sonoma 14 or later, Apple Silicon or Intel | Open perplexity.ai in Safari, choose File > Add to Dock, then select Add | Apple guide to Safari web apps |
| macOS Ventura 13 or older | Use Perplexity in Safari, Chrome or Firefox and bookmark it | perplexity.ai |
| You also carry an iPhone or iPad on iOS 18 | Install the phone app and sign in with the same account | App Store listing |
Safari saves the web app to the Applications folder in your home folder. It also opens from Spotlight.
Is Perplexity free on PC and Mac?
The download costs nothing on every platform. The Microsoft Store lists the Windows app at $0.00, and the App Store and Google Play list the phone apps as free.
Install the free app and start on a free account. Cited answers, voice questions, follow-ups and the Library all work on a free account. Perplexity Pro is an optional subscription, and on iPhone it bills through your Apple account.
A site that charges for a Perplexity setup file is not Perplexity AI. The app itself is always free.
Cancel a Pro subscription bought on iPhone from the Manage Subscription section of your Apple account.
Should you install the Perplexity app or the Comet browser?
Perplexity AI publishes two Windows apps on the Microsoft Store, and both are free. They sign in with the same account.
Install the Perplexity app if you want answers in their own window. Install Comet only if you want to replace your web browser. The Perplexity app is a 244.9 MB answer engine that sits next to the browser you already use. Comet Browser is a full web browser with the assistant built into every page, so it changes how you browse.
Comet is listed as Comet Browser on the Microsoft Store and as Comet on the App Store for iPhone and iPad.
