Perplexity AI is an answer engine that combines web search with large language models to deliver sourced, up-to-date answers for researchers, professionals, and everyday users.
About
Perplexity AI is a conversational answer engine that responds to questions with concise summaries drawn from live web sources, citing the pages it used. It addresses a common frustration with both traditional search engines and standalone chatbots: search results require users to click through and synthesize links themselves, while chatbots can produce answers without verifiable sources or current information. Perplexity pairs search indexes with large language models so that each reply is grounded in retrieved web content.
Users type a question in plain language, and the system searches the web, reads relevant pages, and composes a direct answer with inline citations. Follow-up questions keep the context of the conversation. The product is developed by Perplexity AI, Inc., a San Francisco-based company founded in 2022, and is available on the web as well as through mobile apps.
