Google has switched on Universal Cart in the United States, a tool that lets shoppers collect and monitor products they find across Google Search and the Gemini app in a single, persistent cart.
First previewed at Google I/O in May, the idea is to end the tab-juggling that defines online shopping. Find something you like, save it to the cart, and move on; when you return, your items and progress are still there. Because the cart can pull products from multiple retailers, it acts as a central hub rather than another store's basket.
Google says the cart also watches the market for you, sending notifications when a saved product's price drops or an out-of-stock item returns. At checkout, it can take credit card perks into account and surface relevant promo codes, and purchases run through the Universal Commerce Protocol, an open standard Google introduced earlier this year to help AI agents and retailers work together across the shopping journey.
Universal Cart joins a fast-crowding field. It sits alongside conversational product discovery in Search's AI Mode and Google's 'Let Google Call' agent feature, while Amazon, OpenAI and other rivals are building their own agentic commerce tools.
Launching in mid-October is no accident: with the holiday season approaching, whoever owns the shopper's cart owns a growing share of the season's spending.
