WhatsApp Koperasi (WaKop) is an AI-powered WhatsApp assistant that transforms village cooperatives into digital stores without requiring customers to install a new application. By understanding natural conversations, the AI agent automatically executes backend functions such as checking product availability, creating orders, updating inventory, and retrieving sales reports, providing an experience that feels like chatting with a cooperative staff member instead of navigating a traditional e-commerce interface.

The platform automatically identifies users based on their WhatsApp number using a tiered recognition system (cooperative member, returning customer, or new customer), eliminating the need for login or account creation. Role-based access enables cooperative staff to manage inventory and administrators to request business insights directly through WhatsApp, with all authorization securely enforced on the backend.

Customers can complete the entire purchasing journey from product inquiries and registration to delivery selection and QRIS payment through Midtrans within a single conversation. Supporting multiple cooperatives, WaKop intelligently routes orders to the nearest cooperative based on registered village and sub-district information. When an item is unavailable, the AI proactively recommends the same product from the next closest cooperative, enabling seamless collaboration across the cooperative network and creating a scalable digital commerce infrastructure for village cooperatives.
