# AI Search Engine

> An AI search engine answers a query by generating a synthesized response from retrieved sources rather than returning a ranked list of links.

*Core concept* · *AI Search Infrastructure*

## Definition

An AI search engine is a system that answers a query by generating a synthesized response from retrieved sources rather than by returning a ranked list of links. It pairs a language model with a retrieval layer, reading documents and composing an answer that cites them. The category covers standalone assistants and the generated answer surfaces built into conventional search.

## Why It Matters for AI Search

The defining move of an AI search engine is that it reads and rewrites rather than ranks and lists, which changes the unit of success from a clicked position to a cited source. A brand competes to be part of the material the engine synthesizes and to be named when it is. Because these systems retrieve at query time and ground their answers in what they find, presence in the retrievable record is the price of entry. Everything else in AI search optimization follows from how these engines actually assemble an answer.
