Target is the latest retailer to put generative artificial intelligence tools in the hands of its workers, with the goal of improving the in-store experience for employees and shoppers. On Thursday, the retailer said it had built a chatbot, called Store Companion, that would appear as an app on a store worker’s hand-held device. The chatbot can provide guidance on tasks like rebooting a cash register or enrolling a customer in the retailer’s loyalty program. The idea is to give workers “confidence to serve our guests,” Brett Craig, Target’s chief information officer, said in an interview.
