## TL;DR
AI for retail includes checkout-free stores, product recommendations, demand forecasting, inventory visibility, dynamic pricing, and visual search. Public claims should avoid unsupported revenue or adoption numbers unless a source reports that exact metric.

## Core Explanation
Retail AI connects data about products, customers, inventory, stores, and digital behavior. Recommendation systems personalize discovery, computer vision can support shelf monitoring or checkout-free shopping, and pricing systems can learn from demand and inventory signals.

## Detailed Analysis
Retail systems operate in sensitive contexts: pricing fairness, privacy, surveillance, returns, and accessibility all matter. Strong evidence identifies whether a claim is about a product feature, an academic method, a pilot, or a measured business outcome.
