## Definition

Perplexity is an AI-powered answer engine that retrieves and synthesizes real-time web content to answer user queries with cited sources. It is one of the most citation-transparent AI search platforms — explicitly showing which sources were retrieved and referenced for each response.

## Why It Matters for AI Search

Perplexity's citation transparency makes it one of the most trackable AI search platforms for brands. A brand that appears as a cited source in Perplexity responses gets explicit attribution and a direct link. Because Perplexity retrieves current web content in real time, technical accessibility and content freshness matter more than training corpus presence.
