OpenAI Adds Shopping Function to ChatGPT -- No Advertising, No Sponsored Products, Neutral Information-Based Product Recommendation, Signal Shot of AI Consumer Copilot Era: On April 28, 2025, OpenAI newly introduced a personalized shopping recommendation function in ChatGPT. This is interpreted as a signal showing OpenAI strategy to formally enter the AI-based commerce market. The ChatGPT shopping function allows users to naturally input their requirements -- simply asking recommend a small espresso machine under 200 dollars -- and ChatGPT searches for matching products and presents results in product card format including images, prices, ratings, and reviews. The commercial significance: Google Shopping and Amazon product search have been the dominant product discovery channels; ChatGPT shopping represents a third path where AI-mediated product discovery may be preferred for complex, preference-intensive purchases; the no-advertising model is a deliberate positioning -- by explicitly not accepting payment for product placement, OpenAI claims the AI recommendations are based purely on product merit, creating trust that advertising-funded recommendation systems cannot claim; the AI consumer copilot concept positions ChatGPT as a shopping advisor who helps the consumer make better decisions rather than a retailer optimizing for transaction revenue.
