Our Verdict
Perplexity is the cleanest expression of AI-native search: every answer arrives with citations, follow-up questions refine the query, and the focus modes separate quick lookups from deep research. It will not replace primary sources for consequential decisions, and occasional mis-syntheses mean you should still click through — but as a research starting point and fact-checking layer, it has largely replaced traditional search for many professionals.
