Requirements

What You'll Need Before Installing

A Modern Web Browser

Chrome, Firefox, Edge, or Safari — any up-to-date browser will work perfectly.

Internet Connection

A stable broadband or Wi-Fi connection is required for Perplexity to search and process queries.

An Email Address

Optional but recommended — creating a free account lets you save your search history and preferences.

A Device

Works on Windows PC, Mac, iPhone, Android, or any tablet. No special hardware needed.

Installation Overview

Your Journey at a Glance

The entire setup process takes under five minutes. Whether you prefer using Perplexity in your browser or as a dedicated app on your phone, this guide covers every path clearly and simply.

Step 1

Open Your Web Browser

Begin by launching your preferred web browser on your device. Perplexity works seamlessly with all major browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, and Apple Safari.

For the best experience, ensure your browser is updated to its latest version. You can check this in your browser's settings menu under "Help" or "About." An outdated browser may cause display issues or slower performance.

Step 2

Navigate to the Perplexity Website

In your browser's address bar at the top of the screen, type the following address and press Enter:

You will be taken directly to the Perplexity AI homepage. The page features a clean, minimalist design with a central search bar — similar to a traditional search engine but far more powerful beneath the surface.

Do not search for "Perplexity" in a search engine like Google — always type the URL directly to ensure you reach the official website.

Step 3

Explore the Homepage

Once the Perplexity homepage loads, take a moment to familiarise yourself with the layout. At the centre of the page, you'll find the main search bar where you can type any question or query.

Search Bar

The primary input field. Type any question here — from quick facts to complex research topics.

Sign In / Sign Up Button

Located in the top-right corner. Click here to create your free account or log in to an existing one.

Focus Modes

Options below the search bar let you filter searches by category — Web, Academic, Writing, and more.

Step 4

Create Your Free Account

Click the "Sign Up" button in the top-right corner of the homepage. Creating a free account is entirely optional but highly recommended — it saves your search history and personalises your experience.

You will be presented with several sign-up options:

01

Sign up with Google

The quickest option — links your existing Google account securely.

02

Sign up with Apple

Ideal for iPhone and Mac users already in the Apple ecosystem.

03

Sign up with Email

Enter your email address and create a password manually.

Step 4a

Signing Up With Email — Step by Step

1

Enter Email

Type your email address into the field provided and click "Continue."

2

Check Your Inbox

Perplexity sends a verification link or one-time code to your email address.

3

Verify & Confirm

Click the link or enter the code to confirm your email and activate your account.

Step 5

Choose the Free Plan

After creating your account, Perplexity may display a screen offering plan options. You will see the Free Plan alongside the paid Pro Plan. Simply select "Continue with Free" or "Start for Free" to proceed at no cost.

The free plan is genuinely capable and includes unlimited standard searches. You are never obligated to upgrade, and no credit card details are required at any stage of the free sign-up process.

Step 6

You're In — Make Your First Search

You are now ready to use Perplexity AI! Click on the search bar at the centre of the screen and type any question — just as you would with a regular search engine. Then press Enter or click the search arrow.

Try starting with a simple question such as "What is the weather like in London today?" or "Explain quantum computing in simple terms." Perplexity will generate a clear, sourced answer in seconds.

Troubleshooting

Common Issues & How to Fix Them

Page Won't Load

Check your internet connection first. Try refreshing the page with F5 or Ctrl+R. If the issue persists, clear your browser cache via Settings → Privacy → Clear Browsing Data.

Can't Receive Verification Email

Check your spam or junk folder. Add no-reply@perplexity.ai to your safe senders list and request a new code from the sign-up page.

App Won't Install on Mobile

Ensure you have sufficient storage on your device (at least 100MB free). Update your operating system to iOS 15+ or Android 8+ if prompted.

This is rare but may occur during high traffic. Wait a few seconds and try your query again. Rephrasing your question can also help.
