About Perplexity AI

Perplexity is an answer engine, not a search page: ask a question and it searches the live web, then answers with inline citations you can click. Pro subscribers get a model picker to route queries to GPT, Claude or Gemini, Deep Research for long cited reports, Spaces to organize research per project, and Labs to turn findings into spreadsheets or mini-apps. It is secretly perfect for students, journalists and researchers who are tired of sifting through ten blue links. One thing most people do not know: the top Max tier has Model Council, which asks several frontier models the same question and synthesizes their answers — and in 2026 users revolted when Pro limits were cut mid-contract. Use it to research a documentary subject with sources you can cite.
