Everything about Perplexity AI, in one place

Perplexity AI: the answer engine that shows its sources[1]

Perplexity is an AI search engine from Perplexity AI, Inc., a US company. You ask a question in plain language; it searches the live web and writes an answer with numbered citations you can check. This guide explains its products, plans and features, and points you to the official pages.

Your question opens on the official Perplexity site in a new tab. We don't collect what you type.

Ask once. Perplexity reads the web and answers with numbered sources.

The basics

What is Perplexity AI?

Perplexity AI is an AI-powered answer engine. Instead of giving you a page of blue links, it reads current web pages for you and writes a clear answer, with a numbered citation after each claim so you can check where it came from.

It's made by Perplexity AI, Inc., a San Francisco company founded in 2022 by Aravind Srinivas (CEO), Denis Yarats, Johnny Ho and Andy Konwinski. It works on the web, on iPhone and Android, and inside its own Comet browser.

Help & FAQ

Perplexity AI: Frequently Asked Questions

Popular topics and answers about Perplexity, its apps and downloads. Pick a topic or open a question below.

General questions

Is Perplexity free?

Yes. The free plan includes cited AI search and the Comet browser. Paid plans add higher limits, model choice, more Deep Research and agent features.

How is Perplexity different from ChatGPT or Google?

Perplexity is built around search: each answer is grounded in current web pages and lists its sources inline. Google returns links you read yourself; general chat assistants answer from their training unless they search.

Are Perplexity's answers always accurate?

No AI tool is always right. Citations make it easier to verify a claim, so open the sources when the answer matters, especially for health, legal or financial questions.

What's the difference between Pro and Max?

Pro ($20/month) suits most heavy users. Max ($200/month) mainly adds much larger agent credits, Model Council and early access to new features, rather than better everyday answers.

Is there a student discount?

Education Pro costs $10/month for verified students. Promotions from schools and phone carriers come and go, so check the official site for current offers.

Is this the official Perplexity website?

No. perplexitiai.com is an independent guide. We never ask for your Perplexity password or payment details. To sign in or subscribe, go to perplexity.ai directly.

App & download questions

Where can I download the official Perplexity app?

Only from official sources: the Apple App Store (iPhone and iPad), Google Play (Android), and perplexity.ai for the web and any desktop apps. Avoid third-party download sites, which may bundle fake or unsafe versions.

Is the Perplexity app free to download?

Yes. The app is free to download and use on the Free plan. You can upgrade to Pro or Max inside the app if you want higher limits and extra tools, but downloading and basic use cost nothing.

How do I install Perplexity on Android?

Open Google Play, search for “Perplexity”, check the developer is listed as Perplexity AI, Inc., then tap Install. Open the app and sign in or continue as a guest. Installing from the Play Store keeps the app updated automatically.

Can I use Perplexity on an iPhone or iPad?

Yes. Get the Perplexity app from the Apple App Store on iOS and iPadOS. It includes voice mode and home-screen widgets. The Comet browser is also available on iPhone as a separate app.

How do I access Perplexity on Windows or Mac?

The simplest way is to open perplexity.ai in any browser — no install needed. Perplexity also lists desktop options on its official site; use the download links there rather than third-party sites. The Comet browser runs on both Mac and Windows.

Can I use Perplexity without installing an app?

Yes. Everything works in a normal web browser at perplexity.ai, on phones and computers alike. The apps mainly add convenience, such as voice input, widgets and notifications.

Do I need an account to use the app?

You can ask questions without an account, but signing up (free) saves your history and Spaces across devices and unlocks your plan's features. An account is required for Pro, Max and Enterprise.

Why is Perplexity unavailable for my device or country?

App availability can vary by region and by operating-system version. If the app won't install, update your OS to a supported version, or just use perplexity.ai in your browser, which works almost everywhere. Check Perplexity's Help center for the current list of supported regions.

How do I update the Perplexity app?

Apps from the App Store or Google Play update automatically, or you can update manually from the store's “Updates” section. The web version at perplexity.ai is always the latest and needs no updating.

Is Comet the same as the Perplexity app?

No. The Perplexity app is for searching and getting answers. Comet is a full web browser with the Perplexity assistant built in, so it can read pages you visit and act across tabs. They're separate downloads, and many people use both.

For Android, install from Google Play rather than a standalone APK file. APKs from unofficial sites are a common way malware is disguised as a real app. This is an independent guide and never hosts app files or asks for your password.
