## Definition & overview

AI search combines information retrieval with AI-generated answers. A system may search the web or a knowledge collection, select evidence and compose a response; not every model answer uses live search.

## Analogy & mental model

A researcher collects documents before writing a briefing rather than answering from memory alone.

Separate live-search citations from model-only brand mentions when measuring visibility.

## Why it matters

AI search can surface information through answers rather than only lists of links. It is useful to distinguish discovery, citation, referral traffic and enquiry generation, because these are different stages. A company can be mentioned frequently yet receive no relevant commercial visits.

## Practical business example

An owner compares ways to automate quote follow-up. A helpful source explains both the workflow and cases where a human must still intervene.

Illustrative scenario, not a client case study or promised result.

## How it works

1. The system interprets the request and may expand it into related searches.

2. It retrieves and selects passages from available sources.

3. The model composes an answer, sometimes with links that users can follow.

## Core components

- Search or retrieval layer

- Source selection

- Generated answer

Not every AI product searches on every request, and a fluent answer is not evidence of live retrieval.

## AI search vs Model-only response

A model-only response can draw on learned patterns without live retrieval. AI search introduces retrieved evidence, although that evidence may still be misread.

## Frequently asked questions

What does AI search mean?
AI search combines information retrieval with AI-generated answers. A system may search the web or a knowledge collection, select evidence and compose a response; not every model answer uses live search.

How is it different from Model-only response?
A model-only response can draw on learned patterns without live retrieval. AI search introduces retrieved evidence, although that evidence may still be misread.

What is a sensible first step for a small business?
Separate live-search citations from model-only brand mentions when measuring visibility. The system interprets the request and may expand it into related searches.

What limitations should I keep in mind?
Not every AI product searches on every request, and a fluent answer is not evidence of live retrieval.
