Agentix

Built for the zhezHACK pitch: an AI salesperson that answers a small business's clients in WhatsApp in Kazakh and Russian, takes the order and sends a Kaspi payment link, plus a cabinet where the owner sees chats, orders and what the AI said.

Convex behind both the cabinet and the WhatsApp Cloud API webhook, an Astro landing page in front. Owners get Telegram notifications and a daily summary; sums in orders are checked in code, not trusted to the model.
