ServeBot
WhatsApp Ordering Assistant for Restaurants
ServeBot is a WhatsApp ordering assistant for restaurants. Guests order by text or button taps — Level-1 routing handles menu, cart, checkout, and order status without an LLM. Anything open-ended goes to a shared LangGraph agent with scoped tools. Owners get a Next.js dashboard with live orders and an AI assistant for sales & ops.
Your guests already message on WhatsApp. ServeBot takes the order, updates the cart, sends payment links, and answers menu questions — while your kitchen dashboard stays in sync and your admin AI answers “how many pending orders right now?”

Key Capabilities
Two-level agentic routing
intent_router matches keywords and button payloads first. Deterministic paths hit menu_qa, cart_edit, checkout, and order_status. Unmatched or “Ask Anything” falls through to the shared LLM agent — fast when rules apply, smart when they don’t.
Guest live_chat tools
search_menu, get_menu, edit_cart, checkout_link, get_order_status, and knowledge-base RAG (pgvector) — the agent loops until the reply is ready, then send_reply hits WhatsApp Cloud API.
Owner live_dashboard AI
Dashboard Chat uses the same agent with scoped tools: summary, sales reports, inventory, menu availability toggles, and top-selling items — without exposing guest cart tools.
Restaurant admin UI
Next.js dashboard for today’s stats, orders, menu CRUD, customers, WhatsApp announcements, settings, and the AI assistant — JWT-secured against the FastAPI API.
Durable conversation memory
LangGraph AsyncPostgresSaver checkpoints per thread (whatsapp:<phone> / dashboard:admin) so multi-turn carts and admin chats survive restarts.
Production Meta WhatsApp stack
Signature-verified webhooks, wamid dedupe, interactive list/button payloads, and agent-driven replies via Meta Graph API — plus optional Langfuse tracing.
