Google Universal Cart: AI agent combines purchases from different stores

Google has launched Universal Cart — a service that consolidates products from different online stores into a single shopping cart, making the search and comparison process as convenient as possible.

How Universal Cart Works

Universal Cart integrates with Google Shopping and creates a single entry point for search and purchasing. After searching on Google, users can add products from different sellers to Universal Cart, where the system synchronizes all items, displays current prices and delivery options. Products can be easily compared across stores by price, availability, delivery time, and reviews — without needing to visit each website separately. Checkout happens directly from Google, although payment processing can be delegated to partners. Essentially, Google takes on the role of a supermarket, where products from different shops sit on the same shelf.

Why It's Better for Buyers

• A single place to search and compare products from different stores
• Price tracking with automatic notifications about discounts and price reductions
• Personalized recommendations based on search and purchase history
• Simplified checkout without multiple transitions between websites and repeated data entry

Google has tested this approach in several markets and is gradually expanding availability. In the first phase, Universal Cart is available only in the USA for products from partner stores. According to the company's plans, in the coming months the service will expand to other countries and cover more product categories.

This Is Preparation for AI Shopping

Universal Cart is an intermediate step toward a more ambitious idea: AI agents that will not just show products, but independently make purchases on behalf of the user. Google is already developing specialized shopping agents — they will be able to analyze preferences, set a budget, and consider purchase history, then place orders without human involvement. The company positions this as a more "fun" way to shop, since the user can completely delegate the boring process of selection and comparison to AI.

"We want shopping to become a more engaging and convenient process,"

Google's description states.

The idea sounds attractive: AI learns your preferences, remembers the prices you like, and at the right moment buys what you need without your involvement. But it also means Google gets complete control over your purchasing decisions.

What This Means

Internet retail is undergoing a structural shift: from a model of independent stores (which competed directly) to a platform model, where the platform (Google, Amazon, and others) becomes the main interface. AI here is not just a search assistant, but an autonomous decision-making agent. This gives the platform disproportionate control over the "search → choice → purchase" chain and a vast amount of data about the preferences of millions of users. For traditional stores, this means even greater dependence on platform algorithms.
