Google says AI agents spending your money is fun

At Google I/O, Google rolled out Universal Cart—an agentic AI shopping assistant built on an open commerce standard—designed to consolidate purchases across retailers and automate deal-checking, compatibility alerts, and checkout-ready decisions. Google’s VP o

A CPU and motherboard sat side by side in a shopper’s cart during a live demo at Google I/O—and the AI stepped in. It didn’t just recommend. It warned that the two devices weren’t actually compatible.

In another moment from the same presentation, the assistant nudged a user toward a discount by using a different credit card.

These weren’t just clever suggestions. They were examples of how Google wants agentic AI to take over the messy middle between “Add to cart” and “Checkout.” And at a preview call ahead of I/O. Google’s VP of Ads and Commerce. Vidhya Srinivasan. described the goal plainly: these features will “make shopping more fun.”.

Universal Cart is Google’s latest push. introduced at the Tuesday developer conference. as an AI-powered shopping assistant that consolidates purchases into one place. It sits under what Google calls the Universal Commerce Protocol. or UCP. an open standard for commerce and agentic AI co-developed with major retailers including Target. Shopify. Wayfair. and Etsy.

The pitch is simple: one cart, multiple retailers. With UCP, retailers can operate on Google Pay while still giving customers access to retailer-specific data such as loyalty programs or credit cards.

Universal Cart also expands where Google’s AI can “see” what you’re buying. The agentic AI gets access to your product selections across the company’s ecosystem—YouTube, Gmail, Gemini, or search. From there, it can provide insights on what you’re buying, make suggestions, and open the door to other interactions.

The system is designed to work in the background once you start shopping on Google. After you add items to a cart. the agent looks for better deals. checks whether a sale price is actually worth it. and highlights specific sale information. In the demo. it flagged the compatibility issue between a CPU and motherboard. and in another case it prompted the user to take advantage of a discount by switching credit cards.

But convenience here comes with a trade that’s hard to miss: the AI isn’t only scanning for bargains. The features are also tracking behavior—keeping tabs on what you’re looking at—and predicting future purchases.

That’s where the “fun” pitch lands for Google. The idea is that shoppers speak naturally to the AI, then give it permission to carry out actions on their behalf, turning routine buying into something closer to automated housekeeping.

Google has even used the term “digital laundry” for what Gemini and agentic AI are especially good at—handling routine tasks—and the company is betting that this shopping automation is the first step.

It’s not just a new feature. In January. Google demonstrated a similar concept with Chrome’s Auto Browse feature during a press demo—showing a user giving Gemini permission to take actions in the browser. In that earlier example, the user showed Gemini a photo of party decorations. Gemini analyzed the image, located the streamers, balloons, and decorations, and added them to the cart.

The through-line is clear: with UCP, Google says the checkout experience shouldn’t force you to jump between separate tabs for Etsy, Amazon, and Walmart. The goal is that it all lands in one place.

Retailers. of course. want this as frictionless—and as personalized—as possible. because conversions often depend on how quickly interest becomes purchase. Google continues to emphasize how agentic AI can carry out routine actions in the background. and its shopping features are built to do exactly that.

The hardest question isn’t whether an assistant can catch a compatibility problem or spot a better card. It’s what it means when the workflow becomes automatic—when the AI is not just helping you decide, but watching what you look at and predicting what you’ll buy next.

Google’s ultimate vision is a shopping experience that feels conversational: tell the AI what you want. then let it handle the repeating trips. If you buy the same kind of toilet paper every month. the system would be there to make sure you don’t forget—adding it to your cart and even making the purchase itself.

And that brings the moment from the demo back into focus. If the middle steps are handled while you sleep, the “fun” part isn’t only the convenience—it’s the shift in control, from shopper to agent, executed in the background.
