Perplexity AI: Your “Answer Engine” for the Modern Internet

❓ What is Perplexity AI?

Q: What exactly is Perplexity AI?
A: Perplexity AI is an “answer engine” that combines web search, large language models (LLMs), and real-time information to respond to user questions with direct, conversational answers. Instead of giving you a list of links, it synthesizes information and includes source citations, so you can verify what you read.

Founded in 2022 by Aravind Srinivas, Denis Yarats, Johnny Ho, and Andy Konwinski, Perplexity AI, Inc. is headquartered in San Francisco. It has rapidly gained popularity by offering both free and paid (Pro) tiers.
