What Is Perplexity? A Beginner's Guide to AI-Powered Search
Markus Maila, CTOPerplexity is an AI-powered search engine. You ask a question in plain language, and instead of giving you a list of links, Perplexity reads the web for you, synthesizes the information, and gives you a clear answer with numbered source citations so you can verify everything.
Think of it as the answer engine that Google should have been. No ads cluttering the results. No SEO-stuffed articles to wade through. Just a direct, sourced answer to your question.
As of early 2026, Perplexity handles over 780 million queries per month across 238 countries. It uses its own proprietary Sonar model family for search, and gives Pro subscribers access to frontier models from Anthropic, OpenAI, Google, and xAI, all within one interface.
You don't need a technical background to use it. If you can type a question, you can use Perplexity.
How to Get Started
Getting started takes about a minute:
- Go to perplexity.ai, the official web app. No download needed.

That's it. Perplexity will search the web, read the relevant pages, and give you a sourced answer in seconds.

More than a traditional search engine. Here's a breakdown of everyday tasks versus more advanced use cases:

Focus modes
Perplexity lets you fine-tune how it searches with Focus modes:
- Web, general internet search (default)
- Academic, restricts results to peer-reviewed journals and scholarly publications
- Math, powered by Wolfram Alpha for computations and data analysis
- Writing, optimized for generating and editing text
- Video, searches YouTube and video sources with summaries and timestamps
- Social, searches social media platforms
How citations work
Every Perplexity answer includes numbered inline citations like [1], [2], [3]. Each number links to the original source. You can click any citation to see a snippet from the source or visit the original page. This makes it easy to verify any claim, something traditional search engines and most AI chatbots don't offer by default.
3 Pro Tips for Better Results
The way you ask shapes the answer you get. Here are three habits that make a real difference:
1. Be specific about what you need
Don't search like Google. Instead of typing keywords, ask a complete question with context:
- Instead of: "best CRM 2026"
- Try: "What are the top-rated CRM tools for small businesses with under 20 employees in 2026? Compare pricing and key features."
Perplexity understands natural language. The more specific you are, the more useful the answer.
2. Use follow-up questions
Perplexity remembers the conversation context. After getting an initial answer, drill deeper:
- "How does the pricing compare for annual plans?"
- "Which of these integrates with Google Workspace?"
- "Show me user reviews for the top two options."
Each follow-up builds on what came before, so you don't have to repeat yourself.
3. Pick the right Focus mode
Use Academic when you need peer-reviewed sources, not blog posts. Use Math when you need calculations, not explanations. Use Video when you want to learn visually. Matching the Focus mode to your task filters out noise and gives you better results.
Frequently Asked Questions
Is Perplexity free?
Yes. The free plan gives you basic web search with the standard Sonar model. You get a limited number of daily queries. Pro ($20/month) unlocks unlimited searches, advanced models, and Deep Research.

Perplexity grounds every response in web sources and cites them transparently. That said, the quality depends on the sources available. Always click through to verify critical information, especially for legal, medical, or financial decisions.
