The Responder adds an AI chat agent to your storefront that works from your real store data. It recommends products with interactive cards, suggests complementary items, and knows the page a shopper is on. It can add items to the cart, issue coupons within rules you set, and make cart-threshold and free-shipping offers. It tracks orders after verification, answers from your FAQs and policies, and summarizes reviews. You manage tone, coupon rules, and product relationships in the Shopify admin.
