Walmart is digging deeper into the two biggest tech trends of the moment: generative AI and augmented reality. The mega-retailer announced Tuesday afternoon during CES that its latest iOS app features generative AI-powered search. Customers can now view a list of products across different categories by typing in an activity, such as a "football watch party," versus having to hunt for specific items one at a time, like "Doritos" and then "napkins." Plus, Walmart unveiled a new augmented reality feature that lets customers solicit feedback from friends about potential clothing purchases through various mobile sharing apps. Walmart executives say they hope AI can be especially useful in helping customers find what they are looking for, noting that they see shopping-related searches as a not-yet-solved problem. Meanwhile, Walmart wants to take advantage of this week's global tech conference in Las Vegas to show off its tech chops.
