This n8n workflow enables users to manage their Google Calendar through natural language interaction via Telegram, supporting both text and voice inputs. The process begins when a user sends a message on Telegram, which can be either a text or a voice message. If it’s a voice message, the workflow downloads the file and transcribes it into text using OpenAI’s Whisper model. The extracted text, whether originally text-based or transcribed from voice, is then analyzed by GPT-4 to interpret the user’s intent. This AI-driven understanding determines whether to create, update, fetch, or delete a calendar event.

The workflow interacts with Google Calendar through dedicated nodes for creating, updating, retrieving, or deleting events based on the AI’s decision and input data. After executing the calendar action, the system sends a confirmation or result message back to the user on Telegram, completing a seamless, AI-supported calendar management experience.

This automation is ideal for individuals who prefer managing their schedule through conversational commands and need a flexible, hands-free way to keep their calendar updated, whether at home or on the go.
