When you're shopping, you probably have a general look in mind. But how do you describe that to a shopping site? eBay might have an answer: have AI figure it out. It's implementing a feature that uses computer vision to find items that resemble what you're looking at. Tap the three-dot menu next to a product and it'll give you both simple category buttons (such as "athletic shoes") as well as a "looks like this" option to find visually similar items. Eye a green set of sneakers, for instance, and you should see comparable footwear without having to construct an elaborate search.
