What is Perplexity?
Perplexity answers questions using web search and presents source citations alongside its responses. This makes it a useful starting point for discovering material, comparing unfamiliar topics, and following a research thread through additional questions. Its help center also describes deeper research and creation capabilities on eligible plans. A citation is a route to verification, rather than proof that a summary is correct.
