Perplexity is an AI search engine that gives you direct answers instead of a list of blue links. It searches the web in real time, summarizes the findings, and cites every source it used, making it one of the fastest growing alternatives to Google.
What Is Perplexity?
Founded in 2022 by Aravind Srinivas, Johnny Ho, and others, Perplexity uses large language models combined with live web search. You ask a question, and it returns a synthesized answer with inline citations to the articles and pages it read. It is available on the web and as a mobile app.
Key Features

- Follow-up questions: Refine your answer in the same conversation thread.
- Collections: Save your searches and organize them into topic collections.
- Pro Search: Deeper research that reads more sources and returns longer answers.
- File upload: Upload a PDF and ask questions about its contents.
Pricing
Perplexity has a free tier with limited queries. Pro costs $20 per month and adds unlimited Pro Search, file uploads, and access to GPT-4o and Claude models.
