Perplexity

An AI-native answer engine launched in 2022 and built as a search replacement. Every response includes cited, clickable sources — making it one of the most transparent engines for tracing where an answer came from.

Also called: Perplexity AI

Common prompts: "what is Perplexity," "Perplexity vs Google," "is Perplexity better than ChatGPT"

Definition

Perplexity is the AI-native search engine launched in 2022. Unlike chat-first engines, Perplexity is built explicitly as a search replacement — every answer includes cited sources, and the interface prioritizes retrieval transparency over conversational flow.

Why it matters

Perplexity is the answer engine closest in function to traditional search. Its user base over-indexes on researchers, journalists, and B2B buyers performing structured discovery. The citations are explicit, named, and clickable — which makes Perplexity the easiest engine to audit and the cleanest signal of which sources are driving category answers. Many AI Visibility audits start with Perplexity for that reason.

Example

An Everything-PR Citation Share study testing 30 prompts on Perplexity reveals the full citation graph for a category in one pass — every source named, every URL clickable. The same audit on ChatGPT requires manual reconstruction of the source list. Perplexity's transparency makes it the diagnostic engine for the category.
