## Summary

The article analyses the limits of generative AI in retail when it has no access to local store data (stock, opening hours, reviews, competition). According to the figures cited, nearly three in four retailers have launched generative AI initiatives but only 11.5% have deployed it at scale. The author explains that an AI fed with national data risks standardising marketing recommendations instead of tailoring them to each store, with consequences such as a poorly allocated budget or a broken customer promise. He cites a Google test in the United States checking in-store product availability, and a 2026 IFOP/Guest Suite study according to which 45% of users check Google reviews after consulting an AI. The article proposes three conditions to avoid this uniformity: starting from the decision, setting up two-way governance between head office and the field, and keeping a human at the point of decision.
