Perplexity is the AI you use when you would normally open five browser tabs. It combines large language models with live web search to return a written answer that cites its sources inline — so you can verify claims quickly instead of trusting a black box. Pro Search plans queries into multiple steps for deeper questions, Spaces keep research organized across a topic, and Focus modes narrow searches to academic papers, YouTube or Reddit. It is not a replacement for a general-purpose chatbot, but for time-sensitive research it is the fastest tool in the category.
