🧠 Description

This template deploys an AI-powered virtual medical secretary that automates appointment scheduling, rescheduling, and cancellations for clinics and healthcare professionals.
It seamlessly integrates OpenAI for natural language understanding, Google Calendar for real-time booking, and Evolution API (WhatsApp) or Telegram for patient communication.

Patients can chat naturally via WhatsApp or Telegram, receiving empathetic, professional, and human-like responses — while your calendar stays automatically synchronized in real time.

💡 What Problem Does This Solve?

Managing appointments manually is time-consuming and error-prone, often requiring staff to handle repetitive tasks like checking availability, confirming times, or rescheduling.
Traditional systems lack conversational capabilities, forcing patients to call or text staff directly.

This template solves that by creating a conversational AI assistant that interacts with patients through familiar messaging channels, reducing administrative workload and ensuring accurate real-time scheduling through Google Calendar.
