Shoppers increasingly ask ChatGPT, Gemini or Perplexity what to buy. Shelv scans one product page of your online store and shows what an AI assistant can actually read: name, price, stock, barcode (EAN/GTIN), brand, shipping and returns. You get 15 checks, each with a plain-language fix and paste-ready product data. Free, no account. Paid plans add automatic monitoring of 10 or 50 product pages. Built in the Netherlands for small and mid-sized stores.
