Traditional search gives you a list of links and leaves the reading to you. Perplexity is faster for getting a synthesized answer; traditional search gives you more direct control over which sources you trust.

Perplexity vs ChatGPT for Research

For research, Perplexity and ChatGPT play different roles. Perplexity is a search-first assistant that grounds every answer in cited web sources.
