Introducing NovaDesk AI: Building a Stateful Hotel Concierge with LangGraph

Summary

NovaDesk AI is an open-source, stateful hotel concierge built with LangGraph, FastAPI, and Chainlit, demonstrating multi-step agentic orchestration beyond basic chatbots. It integrates advanced RAG via HyDE and query rewriting, state and memory management, and human-in-the-loop (HITL) security for cancellations. The system routes natural language intents to SQLite database transactions for policy Q&A, room bookings, and room service, with strict domain guardrails to prevent off-topic queries.
