When you ask Perplexity a question, it uses advanced AI to search the internet in real time, gathering insights from top-tier sources. It then distills this information into a clear, concise summary, delivering exactly what you need in an easy-to-understand, conversational tone.

How it works

Perplexity goes beyond simple keyword searches. It uses cutting-edge language models like GPT-4.1 and Claude 4.0 Sonnet to understand the context and nuances of your query. Here’s a breakdown of the process:

Understanding your question

Perplexity leverages sophisticated AI to interpret your question, ensuring it knows exactly what you’re asking.

Searching the web

It scours the internet, gathering information from authoritative sources like articles, websites, and journals. Looking for live updates of a soccer game? Perplexity can do that.
Summarizing information

Perplexity compiles the most relevant insights into a coherent, easy-to-understand answer.

Citing sources

Each answer includes numbered footnotes linking to the original sources, allowing you to easily verify the information or explore further.

Ways to search

1. Pro Search: Pro Search is an advanced AI-powered Search which provides comprehensive, in-depth answers to any query. It goes beyond standard search capabilities by conducting thorough research across multiple sources and delivering detailed, well-organized responses.
With Pro Search you can select which AI model you want applied to your answer: Best (our default option, selecting the most suitable model for your question), OpenAI's GPT 4.1, Anthropic's Sonnet 3.7 and many more

2. Research (formerly Deep Research): Perplexity's most sophisticated research, it employs an advanced framework called test time compute (TTC) expansion that mimics human cognitive processes through iterative analysis cycles.

Research performs dozens of searches automatically, reads hundreds of sources, reasons through material autonomously, and delivers comprehensive reports in just 2-4 minutes.
Free users can enjoy up to 3 Pro Searches per day, while subscribers have access to 300+ Searches daily.

Features

Conversational dialogue

Contextual memory

For instance, if you ask, “What are the health benefits of yoga?”
