Shoppable has launched its universal checkout plugin for ChatGPT, enabling 900 million users to discover and purchase products from multiple retailers within a single AI conversation. The integration leverages agentic commerce infrastructure to streamline the path from AI-driven product discovery to a unified, one-click transaction experience. Universal checkout technology allows users to aggregate products from a catalog of 500 million items into a single cart without leaving the AI interface. By utilizing Shoppable's patented commerce infrastructure, the plugin eliminates the need for shoppers to manage multiple accounts or fragmented checkouts across different merchant websites. Features include unified cart consolidation, contextual product discovery using ChatGPT's reasoning, and frictionless redirection to a secure, single-click checkout page. Agentic commerce provides brands with a direct connection to ChatGPT's 900 million weekly active users. Shoppable's Model Context Protocol (MCP) server ensures high-speed connectivity and accurate inventory data across its vast merchant network. The technology is built on 15 years of development and four U.S. patents for multi-retailer transaction handling. "Every big shift in shopping came from removing a step," said Heather Udo, Founder and CEO of Shoppable, noting that agentic commerce hits that point faster.
