This innovative feature allows customers to browse the store without typing, improving engagement and simplifying the shopping process. Miros also offers insights and expert blogging on leveraging AI for product discovery to help grow e-commerce businesses. --- eCommerce loses half of its sales because in this industry nobody knows how to make the products findable. If you can’t find, you can’t buy. No universal taxonomy exists to describe visual items. Shoppers do not know the right words to search for what they like. Meanwhile, because you can’t filter products by how much you like them, you’ll have to browse thousands of products – many of which you’ll dislike. When shopping feels tedious, the shopper quits. Miros gives shoppers a new language to express what they are looking for - far richer and more accurate than any existing search technology.
