Your step-by-step guide to getting started with one of the world's most powerful AI search tools — completely free, no technical expertise required.
Perplexity AI is a next-generation search engine powered by artificial intelligence. Unlike traditional search, it reads the web and delivers direct, cited answers to your questions in plain English.
The free version gives you unlimited access to core AI search features — no subscription required.
Chrome, Firefox, Edge, or Safari — any up-to-date browser will work perfectly.
A stable broadband or Wi-Fi connection is required for Perplexity to search and process queries.
Optional but recommended — creating a free account lets you save your search history and preferences.
Works on Windows PC, Mac, iPhone, Android, or any tablet. No special hardware needed.
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.
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.
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.

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.
The primary input field. Type any question here — from quick facts to complex research topics.
Located in the top-right corner. Click here to create your free account or log in to an existing one.
Options below the search bar let you filter searches by category — Web, Academic, Writing, and more.

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:
The quickest option — links your existing Google account securely.
Ideal for iPhone and Mac users already in the Apple ecosystem.
Enter your email address and create a password manually.
Type your email address into the field provided and click "Continue."
Perplexity sends a verification link or one-time code to your email address.
Click the link or enter the code to confirm your email and activate your account.
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.

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.

Tap the blue App Store icon on your iPhone's home screen.
Type "Perplexity AI" into the search bar at the top of the screen.

For power users on desktop, Perplexity offers a free browser extension for Chrome and Edge. This allows you to access Perplexity directly from your browser toolbar without navigating to the website each time.
Go to chrome.google.com/webstore and search for "Perplexity AI."
Select the official Perplexity extension and click the blue "Add to Chrome" button.
A pop-up will ask you to confirm — click "Add Extension" to complete the install.

Use Writing mode to draft emails, essays, and summaries with AI guidance — all within the free plan.
With a free account, all your previous searches are saved and accessible anytime from your profile sidebar.
The free plan is more than sufficient for everyday searching, research, and general use. Most users never need to upgrade.
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.
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.
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.

Instead of typing keywords, ask complete questions like "What are the health benefits of green tea?" for richer answers.
After receiving an answer, click suggested follow-up questions or type your own to dig deeper into any topic.
Always review the cited sources below each answer. Click any source to read the full original article for verification.
