What Is Perplexity AI?
Perplexity AI is an American AI-driven web search engine that uses large language models (LLMs) to process user queries and generate synthesized, conversational answers based on real-time web search results. Unlike traditional search engines that return a list of links, Perplexity provides direct, concise answers with citations, allowing users to get reliable information faster and with greater clarity.
Founded in 2022 by Aravind Srinivas, Denis Yarats, Johnny Ho, and Andy Konwinski, Perplexity AI launched its flagship search engine in December 2022 and has since expanded to include browser extensions and mobile apps for iOS and Android. The company is headquartered in San Francisco and valued at around $9 billion as of late 2024.
