Perplexity AI is an intelligent research partner that uses natural language and responds to queries with complete, reasoned answers rather than lists of links. The platform fills the gap between rigid chatbots, which are prone to training data reduction, and traditional search engines, which overwhelm users with unnecessary options. Using synthesized information from various authoritative sources, delivered in an instant and in a conversational style, Perplexity has freed users from having to spend time viewing dozens of search results and manually filtering them. The system is supported by web browsers, desktop applications, and mobile applications, and will enable effective research using advanced artificial intelligence technologies wherever users need quick and reliable answers to complex questions.
