Perplexity AI is an artificial intelligence-powered search engine that has fundamentally changed how we interact with information online. Unlike traditional search engines that provide lists of links, Perplexity delivers direct, conversational answers with real-time citations from credible sources across the web.

Founded in August 2022 by Aravind Srinivas, Denis Yarats, Johnny Ho, and Andy Konwinski, Perplexity has rapidly evolved from a startup to a $18 billion powerhouse that’s challenging Google’s search dominance.
