What is Perplexity AI?

Perplexity AI is an AI-powered search engine that combines real-time web search with AI-generated answers. Unlike ChatGPT, Perplexity actively searches the web and delivers answers with cited source references — which dramatically reduces hallucinations. It is positioned as a direct alternative to Google Search for users who want synthesized, conversational answers with transparent sourcing.
