This n8n workflow seamlessly integrates Gmail, Google Calendar, Telegram, and OpenAI to automate email processing, calendar event retrieval, and voice interactions. It enables an AI assistant to listen for Telegram messages, identify and transcribe voice notes, fetch relevant emails and calendar events, and respond intelligently within Telegram. The workflow is designed to create a virtual assistant that manages communications and schedules efficiently, ideal for productivity enhancement or virtual assistant services.

The process begins with listening to incoming Telegram messages. If the message is voice, it is transcribed into text using OpenAI. The workflow also listens for text messages and handles email retrieval, filtering unread emails received after a specified date, and processes calendar data by fetching upcoming events.

The AI assistant, powered by OpenAI, then provides contextual responses based on the retrieved information, with memory stored in window buffer memory for context continuity. The final responses are sent back to Telegram, making this workflow suitable for real-time virtual assistance, automated customer support, or personal productivity tools. Additionally, it integrates Baserow for task and contact management, further extending its utility in task management scenarios.

This workflow is ideal for users seeking to automate communication and scheduling tasks while maintaining a conversational interface via Telegram.
