Subscription Tracker & Reminders with GPT-4, Telegram & Google Sheets

This n8n workflow runs daily at 8:00 AM to scan Google Sheets for upcoming subscription due dates, formats key details using GPT-4 nano for natural language processing, and sends personalized Telegram reminders to users. It also handles incoming Telegram messages, leveraging AI to interpret commands for adding new subscriptions, updating billing info, or querying records, ensuring seamless conversational management without manual intervention.

Key benefits include massive time savings—reducing manual tracking from hours to under a minute daily, equating to 5 hours weekly—and error minimization through automated data handling. The ROI is realized in the first month via labor cost reductions, while scalability supports growing subscription lists effortlessly.

Ideal use cases span small businesses, freelancers, and SaaS teams managing client billings, enabling proactive engagement, accurate records, and integrated insights. Setup requires Google Sheets OAuth, OpenAI API key, and Telegram bot token, with optional email SMTP for broader notifications.
