Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureSmart Search adds an AI chatbot to your store that understands what customers are looking for. Instead of browsing and filtering, customers describe what they need in plain language and get instant product recommendations. The assistant knows your full catalog, answers questions about sizing and policies, compares products side by side, and guides customers through variant selection to add items directly to cart.
Kai adds a chat bubble to your storefront where shoppers ask for products in their own words, like "wireless headphones under $50" or "a black dumbbell set". Every answer comes from your synced product data: real titles, prices, variants and stock. If you don't carry something, Kai says so instead of making it up, and suggests close items you do stock. There is nothing to train or write.
