Manage Google Calendar and Gmail from Telegram with a Claude AI assistant

Telegram AI Personal Assistant — Calendar & Email Manager

This workflow turns a Telegram bot into a fully functional personal AI assistant capable of handling your schedule and inbox through natural conversation. Send it a text message, record a voice note, or snap a photo — it understands all three and responds intelligently.

The assistant is powered by Claude Haiku (via OpenRouter) and comes with a built-in 30-message memory buffer, so it remembers context across a conversation just like a real assistant would. It has full read/write access to Google Calendar and Gmail, meaning it can book meetings, check your availability, send emails, reply to threads, and clean up your inbox — all from a single Telegram chat.

What this workflow does

Multi-modal input handling - Text messages are processed directly - Voice notes are downloaded from Telegram and transcribed using OpenAI Whisper - Photos are downloaded and analyzed using GPT-4o vision, with any caption included as additional context

All three input types are normalized into a unified context object before reaching the agent, so the AI always receives clean, structured input regardless of how the user communicated.

Authorization layer Only the allowlisted Telegram User ID can interact with the assistant. Any unauthorized message receives an instant rejection and the workflow stops — no agent calls are made.
