Perplexity AI

Perplexity is an AI-powered search and research engine that gives direct, cited answers to questions rather than a list of blue links. It searches the web in real time, synthesises findings across sources, and presents answers with inline citations you can verify. Researchers, students, and knowledge workers use it as a starting point for any question that previously required reading multiple web pages.

Perplexity AI features and capabilities, including live web search, citations, the free version, and which plan they need.
