AI is already an integral part of the shopping journey for many European consumers: In a recent McKinsey survey, 63 percent of respondents report using AI-powered tools to compare options and learn about products. More than half of shoppers indicate they are comfortable with AI suggesting options, but they prefer to retain final decision-making authority, note McKinsey’s Katharina Schumacher, Marcus Keutel, Philipp Kluge, and coauthors. For consumer companies seeking to stay relevant in the agentic-commerce era, the question is how to design agentic experiences that provide transparent reasoning, explicit authority, and clear responsibilities.
