Google Introduces Universal Cart for AI Shopping at I/O 2026

E-commerce evolution has influenced online purchases in many ways, and now Google comes up with the largest innovation to date, which is the Universal Cart that will allow consumers to shop for products using artificial intelligence. With the introduction of this technology, consumers can enjoy the convenience of having one shopping cart where they can have all their purchases gathered together. The basic idea behind this technology is the speed and connectivity during online purchases at Google.

The Universal Cart will be integrated with a variety of Google AI technologies, namely Gemini 3.5, Google Gemini Omni, and Agentic AI in Search. All three tools together provide a possibility to understand consumer’s intention, compare products, and even finish the whole purchase cycle at once.

A Single Shopping Experience across the Web.

People usually need to open multiple tabs, manually compare prices, and have various shopping carts on different platforms to do the online shopping task. Google is eliminating these obstacles with its new Universal Cart feature, which combines all of the products selected into a single consolidated shopping cart, managed by artificial intelligence.

Users can now place items from different websites, brands and marketplaces in a single cart without having to switch platforms. For instance, if a person is looking to buy a laptop, headphones, and accessories from various stores, he or she can now manage all of those in one place.

The AI also groups items automatically, and sorts them by type, price, urgency or preference. It can even recommend alternatives, if better offers or higher rated products are available elsewhere.

Know what to buy and at the best price with AI-powered smart recommendations and price comparison.

The most compelling aspect of Universal Cart is its live artificial intelligence price comparison function, which means you don’t have to go through the tedious work of price-checking across several websites. In contrast, users immediately get smart information including the best price available at stores, price alerts and drop notifications, product alternatives, delivery time comparisons, rating and review summaries and more. The system continues to track the products in real-time, so that the users are always presented with the best shopping choice possible! This turns online shopping from a tedious and manual process into a fully intelligent and AI-driven decision making process.

Seamless Checkout With Agentic AI

Universal Cart also integrates seamlessly with Google’s Agentic AI system, enabling users to seamlessly navigate from browsing to checkout with ease. AI can:When the cart is prepared, AI can:

• Auto-fill checkout details
• Suggest payment methods
• Use the Discount Codes automatically
• Optimize delivery options

Make sure to finish the purchases with user approval

While simplifying the process, AI also provides a smooth interface for users to navigate as they proceed through multiple checkout pages.

Personalizing smarter with Gemini Intelligence

The Universal Cart is powered by the Google’s Gemini 3.5 and Gemini Omni models and brings a much more personalized shopping experience that can be tailored to the individual’s behavior, preferences and previous purchases (with their consent). 

It understands what people like and starts recommending products and brands, affordable solutions, seasonal discounts, popular products, and even products that people are going to purchase again and again. This system learns and develops through time, becoming better and better at making predictions. It turns your online shopping into an individually tailored process using artificial intelligence, where each piece of advice is just perfect for you.

Given Universal Cart’s arrival, there is no doubt that the implementation of AI-based shopping experiences by Google will have a great impact on the e-commerce industry. Instead of companies bidding only to get a spot in search, they will have to bid to appear in AI-driven shopping experiences, which will be intention-driven and automated.

Product structuring data, price optimization, quality of descriptions, as well as the ability to create AI-friendly product listings, will become key factors in staying present in the new ecosystem. It will require an innovative way of product comprehension, selection, and analysis based on Artificial Intelligence in the framework of Universal Cart experience.

TheTweaks View: Where will AI-Driven Commerce go next?

From TheTweaks’ point of view, Universal Cart is a major breakthrough in the development of AI-driven commerce ecosystems, which implies that the whole process is handled by artificial intelligence rather than people’s involvement.

Universal Cart by Google seems to be the continuation of their Universal AI plan, after its first phases of Universal Intelligence with Gemini 3.5, Universal Understanding with Gemini Omni, and Universal Agentic AI with Gemini Assistant.

We at TheTweaks consider that the future of online shopping will never be the same because everything will become based on users’ intents, while the job is left to the Artificial Intelligence.

For eCommerce companies, it is about a range of AI interpretations, structured product data and competitiveness in real-time. Users benefit from quicker decision-making, improved pricing opportunities, and a seamless shopping journey.
