Perplexity AI

Built around conversational search, Perplexity AI turns questions into synthesized answers accompanied by links to sources. Follow-up questions can narrow a topic or explore a claim without starting a separate search. That structure suits students and researchers reviewing unfamiliar subjects, as well as journalists and professionals who need to inspect the evidence behind an answer. The service offers free access and paid plans with expanded research tools and access to advanced models.

Pro Search handles more involved questions, while file analysis adds a way to examine uploaded material. Academic search supports scholarly research, and Spaces organize related threads and files. Writing tasks are also supported, though sourced discovery remains its defining emphasis. Citations make checking claims easier, but they do not guarantee accuracy: the linked page still needs to support the answer, and important details need independent review.
