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. ChatGPT is a reasoning-first assistant that explains, analyzes, and writes — and can browse the web on some plans but isn't citation-native. This guide helps you split your research workflow — and offers a recommended combined approach.
