Google Launches Universal Cart, Bringing AI Closer to the Checkout

Google haslaunched Universal Cart in the United States, giving shoppers a single place to manage products discovered across Google Search and the Gemini app.

Users can add items from multiple retailers, return to them across Google services, and receive notifications when a price drops or an unavailable product comes back in stock. Built on Google’s Shopping Graph, which includes more than 60 billion continually refreshed product listings, Universal Cart can also surface promotional codes and recommend payment methods based on the benefits attached to a user’s cards.

When shoppers are ready to buy, they can complete the purchase through Google Pay with participating retailers or transfer the selected products to the merchant’s website. The retailer continues to handle confirmation and customer support as the seller of record.

The launch brings product discovery, comparison, and checkout into a much tighter journey. 

A customer can begin with a search or a conversation in Gemini and move toward a transaction without rebuilding the cart at every stage or navigating separately between retailers.

Google presents Universal Cart as one part of its broader work on the future of commerce, alongside agentic capabilities that can act on a shopper’s behalf. The distinction will become less visible to consumers as more of the work involved in a purchase - organizing options, monitoring prices, applying discounts, and selecting payment methods - is handled within the same AI-assisted environment.

The next competitive question will concern the information these systems use to recommend one product over another.

Prices, specifications, availability, and delivery conditions give an AI agent the structured data required to compare products. 

A purchasing decision also depends on context that is harder to capture in a catalog:how the product performs in practice, who it suits, and which details become important once someone actually uses it.

Authentic video reviews can supply that context. They bring direct human experience into the purchasing journey and allow shoppers to see products through the perspective of customers and creators who know the category.

At AdScout, we are building the infrastructure through which businesses can generate, publish, measure, and learn from this content. Our longer-term work is focused on making authentic product experiences discoverable by AI agents, allowing a relevant review to become part of the recommendation when it can genuinely help someone decide.

Universal Cart shows how quickly AI is moving toward the transaction itself. As that infrastructure develops, trust will increasingly be shaped by the information available before the product enters the cart.

Google is building how AI shops. We are building the trust layer that can help it decide what is worth buying.
