About Perplexity
Perplexity is an AI-native answer engine that responds to questions conversationally while citing its sources inline, functioning as an alternative to traditional search for people who want a synthesized answer with visible provenance rather than a list of links to sort through themselves. It offers several specialized focus modes — including academic search restricted to scholarly sources, and video and social search — plus a Pro Search mode that performs multi-step reasoning, breaking a complex question into sub-questions and researching each before compiling a final answer. Users can also upload files and ask questions directly about their content. Perplexity's citation-first approach has made it particularly popular for research and fact-checking tasks where knowing the source matters as much as the answer itself.
