AI-powered search engine with cited answers
by Perplexity AI, Inc. · Founded 2022
Perplexity is an AI-powered search engine that provides direct, cited answers from real-time web searches.
Perplexity AI has reinvented the search experience by combining the real-time information access of a search engine with the natural language understanding of a large language model. Instead of returning a list of links, Perplexity reads multiple sources and synthesizes a direct, comprehensive answer — with full citations so you can verify every claim.
The platform's real-time web search capability addresses the biggest limitation of traditional AI assistants: knowledge cutoffs. Perplexity always has access to the latest information, making it ideal for research on current events, recent product releases, market data, and any topic where recency matters.
Perplexity Pro ($20/month) unlocks access to multiple frontier models (GPT-4o, Claude 3.5 Sonnet, Gemini) for answering questions, plus Pro Search — a more thorough search mode that asks clarifying questions and performs deeper research before answering. The Spaces feature allows you to create research environments with specific sources and context.
For professionals and researchers, Perplexity has become an indispensable daily tool — replacing Google for complex research questions where a synthesized answer is more valuable than a list of links to read through.

I use Perplexity for every research task now. The cited answers save me hours of reading through search results. Pro Search is particularly impressive — it asks clarifying questions and produces comprehensive, well-sourced reports on complex topics. Essential tool.
The citation feature is invaluable for journalism. I can quickly verify claims, find primary sources, and get up-to-date information on breaking stories. Perplexity Pro is worth every penny of the subscription.

Perplexity is optimized for research and information retrieval with real-time web access and full citations. ChatGPT is a more general-purpose assistant better suited for writing, coding, and creative tasks. Perplexity always cites its sources; ChatGPT may not.
