Ask Sam is a voice assistant for Walmart store employees. Workers can speak or type questions into the Me@Walmart employee app and immediately get answers — like where a product is on the shelf, what its price is, what their schedule looks like, or what messages managers have sent. It was expanded to all 5,000-plus U.S. Walmart stores in July 2020, and employees ask it over 3 million questions per week.

Ask Sam was originally developed for Sam's Club in 2019, then deployed across all Walmart U.S. stores through the Me@Walmart app in July 2020. The tool uses machine learning to improve its accuracy over time as more employees use it. In June 2025, Walmart announced a generative AI upgrade that converts complex internal process documents into simple step-by-step instructions associates can follow. About 900,000 associates use the tool. Although it is employee-facing, it directly improves customer service by helping staff answer shopper questions faster and more accurately.
