What is Google Universal Cart?

Online shopping is spread across many separate stores, so a shopper comparing options can end up juggling browser tabs and screenshots. Shopping cart software is the usual tool for collecting items to buy, and Google Universal Cart is Google's version of a cart that spans stores. Google's help page says it saves products across Google services and manages them in one central location, and items can be added from Google Search and Shopping, AI Mode and Gemini Apps. For participating merchants, Google describes checking out on Google with saved payment methods through Google Pay; for other merchants it helps fill the cart on the merchant's own website. Google says the cart, which is described as available in the U.S., has checkout powered by the Universal Commerce Protocol (UCP), which Google's developer pages call an open standard for commerce.
