Zappy

Chatalog is an AI-powered WhatsApp order management system built for Ghanaian small businesses. In Ghana and across West Africa, WhatsApp is the primary commerce channel; customers already message businesses to place orders. Chatalog formalises this: Customers order in natural language via WhatsApp, and Claude runs an agentic tool-calling loop that understands the request, checks the menu, creates the order, and replies naturally, no app download, no account needed. Store owners get a real-time admin dashboard with a Kanban board (new → confirmed → preparing → in transit → delivered), drag-and-drop status updates that instantly notify customers on WhatsApp, a natural language command bar for updating menu items, and automated payment nudges for unpaid orders. The core is an agentic loop: Claude receives a WhatsApp message, calls tools to read/write the PostgreSQL database, and iterates until it produces a final reply. Tools follow a strict read (get_*, list_*) / write (create_*, update_*, cancel_*) convention. Built with FastAPI + asyncpg on the backend and Next.js 16 + Tailwind v4 on the dashboard.
