Why they built it

Manual appointment scheduling for businesses like dental clinics is inefficient; needed an AI system for availability checks, preference-based booking, queue updates, and automated confirmations

What worked

Seamless LangGraph orchestration, Composio integrations, customizable voice providers, easy deployment on Vercel/LangGraph Cloud, robust testing with LangSmith

What broke or was painful

Pending features like business hours detection, queue/wait time flow, retry logic for failed email/phone confirmations

The result

19 GitHub stars, 5 forks; functional prototype handling voice bookings, email confirmations, and calendar integration for dental clinics and customizable businesses
