Google's new Universal Cart wants to follow you across the internet (techcrunch.com)

At Google I/O, the tech giant unveiled Universal Cart, a centralized shopping hub designed to streamline the online purchasing experience across its platforms. This innovative feature allows users to compile items from various sources—such as Google Search, Gmail, and YouTube—into a single cart. It enhances the shopping journey by providing real-time tracking of deals, price history, and alerts for back-in-stock items. Notably, Universal Cart leverages AI to offer compatibility insights for complex purchases, like custom PC builds, while also optimizing rewards for travel and savings through integration with Google Wallet. The significance of these announcements lies in Google's ambition to transform AI assistants from simple recommendation tools into proactive agents in e-commerce. By introducing the Agent Payments Protocol (AP2), Google enables these agents to make autonomous purchases within customizable limits, thus capturing more customer behavior data and influencing relationships between consumers and merchants. AP2 ensures secure transactions through encryption and offers transparent audit trails, safeguarding user data while enhancing the shopping experience. As Universal Cart rolls out in the U.S. and expands to Canada and Australia, its implications for both the AI/ML community and the commerce industry are profound, potentially reshaping the dynamics of online retail.
