A system is described that identifies, based on contextual information associated with a device that is located at a physical location associated with a merchant, a product that a user of the device is at the physical location to purchase. The system executes an autonomous search query for product information that is predicted to assist the user in completing a purchase of the product, from the merchant, at the physical location. The system sends the product information to the device, and for subsequent output. The system determines whether a degree of likelihood that the user will complete the purchase in response to receiving the product information satisfies a likelihood threshold, if not, the system executes a remote assistance module accessed by the device to provide a virtual environment in which a human provides additional information that the user needs to complete the purchase.
