Amazon handed the data behind Seller Central to outside AI agents
At its Accelerate conference in Seattle on September 23, 2026, Amazon announced an upgraded Seller Assistant and a new Amazon Selling Partner plugin. The plugin connects a seller’s Amazon data, including listing contributions, real-time performance metrics, inventory levels and sales analytics, to the AI agent that seller prefers, and it works with Amazon Quick and Anthropic’s Claude. Setting up the connection takes roughly 60 seconds and requires no coding; the plugin is in beta for U.S. sellers with international expansion planned. GeekWire reports that Seller Assistant is also gaining a canvas feature that builds visual workspaces from live seller data, plus persistent memory of pricing patterns, inventory cycles and growth goals. Amazon says the assistant is deployed to more than 90 percent of its selling partners worldwide, that sellers accept its recommendations more than 90 percent of the time, and that 90 percent of selling partners already use third-party AI tools. Every primary selling account holder can claim a free 12-month Amazon Quick Plus subscription through December 31, 2026, and designate two co-workers for complimentary access.
