Google Launches Universal Cart for US Shoppers

The tool functions as a centralized repository for browsing, ensuring that items saved during a search session remain accessible for later review. By integrating with the Universal Commerce Protocol, an open standard introduced earlier this year, the system enables AI agents to assist with checkout processes and surface relevant promotional codes. Beyond simple list-keeping, the platform actively monitors saved items, triggering notifications when prices fall or previously unavailable inventory returns to store shelves.

This rollout signals Google's intent to anchor its AI-driven shopping ecosystem, competing directly with Amazon and OpenAI for dominance in agentic commerce. The feature complements existing tools like "Let Google Call," which utilizes AI agents to verify local store inventory. By linking credit card benefits to the payment experience, the company is shifting its focus toward making chatbots functional intermediaries in the transaction journey rather than mere research assistants.
