## Definition

Real-time retrieval is the capability of an AI search tool to fetch and incorporate live web content at query time — rather than relying solely on static pre-training data. Perplexity, ChatGPT with web search enabled, and Google AI Mode all use real-time retrieval to ground responses in current information.

## Why It Matters for AI Search

Real-time retrieval makes content freshness and technical accessibility more important than training corpus presence for citation on retrieval-enabled platforms. A brand with excellent current content that is technically accessible to AI crawlers can earn citations from real-time retrieval systems even without significant training corpus presence. For time-sensitive content — news, updated research, recent case studies — real-time retrieval is the primary citation pathway.
