Automated Google Calendar Event Reminder with AI & Telegram

This workflow automates the process of sending personalized reminders for upcoming Google Calendar events using n8n. It begins with scheduled checks (though currently disabled) for events happening within the next hour. When an event is detected, the workflow ensures no duplicate reminders are sent by filtering out previously notified events. It then compiles detailed event information and prompts an AI-powered secretary (using ChatGPT with GPT-4) to craft a friendly, conversational reminder message. Finally, this message is delivered via Telegram, providing a warm and efficient reminder as if from a personal assistant. Practical use cases include managing busy schedules, ensuring timely reminders, and adding a personal touch to automated notifications, especially useful for busy professionals or those managing multiple appointments.
