Perplexity

AI answer engine that cites its sources

Perplexity is a search engine that answers in prose and shows where each claim came from. It is the quickest way to get a sourced overview of a topic, and Pro lets you pick the underlying model. The Comet browser extends the same idea to browsing.

Idéal pour: sourced answers and quick research

Ce qui marche

  • Inline citations you can check
  • Choice of frontier models on Pro
  • Fast, focused interface

Ce qu'il faut savoir

  • Sources are not always the strongest available
  • Less useful for creative work
