See every featureCall.fast gives your store a dedicated phone number answered by an AI agent around the clock. Because it connects to your Shopify store, the agent answers with live data: it finds the caller's order by number, email, or phone and tells them its status, shipment, and tracking. It learns your policies, FAQs, and products automatically when you install, and re-reads your site weekly.
This app helps merchants handle customer inquiries by using store product data and order information to generate accurate replies. After installation, it learns the store’s catalog and order details to assist with common questions about products, availability, shipping, and order status. This reduces manual support work and helps merchants respond to customers more efficiently.
