Choose Perplexity if…

Reach for this when you need to trust the answer, not just get one. Lean toward Perplexity Comet instead if completes multi-step browser tasks directly, filling forms and pulling information without you doing the clicking matters more for your use case.

Lean toward Perplexity instead if every answer comes with citations you can actually check matters more for your use case.
