Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCarti is an AI shopping assistant that sells for you 24/7. It’s far more than a chatbot. Like an in-store AI sales assistant, it reaches out when a shopper hesitates, makes personalized recommendations, compares products, and adds them to cart in chat. It learns your catalog, policies, and reviews to answer questions and close sales, flagging anything it can’t answer so you only fill it in once.
Nacelle Sales adds an AI chat widget to your storefront. Shoppers ask questions, get real product recommendations, and add items to cart — all without leaving the page. The assistant knows your full catalog, your store policies, and what's already in the shopper's cart. Shoppers can even send a photo and get back visually matched products from your catalog. You set the brand voice once.
