Voice & Text Assistant with Telegram, Gemini AI, Calendar, Gmail & Notion

This n8n template demonstrates how to turn a Telegram bot into a personal AI-powered assistant that understands both voice notes and text messages. The assistant can transcribe speech, interpret user intent with AI, and perform smart actions such as managing calendars, sending emails, or creating notes.

Use cases

Hands-free scheduling with Google Calendar

Quickly capturing ideas as Notion notes via voice

Sending Gmail messages directly from Telegram

A personal productivity assistant available on-the-go

Good to know

Voice notes are automatically transcribed into text before being processed. This template uses Google Gemini for AI reasoning.The AI agent supports memory, enabling more natural and contextual conversations.

How it works

Telegram Trigger – Starts when you send a text or voice note to your Telegram bot.

Account Check – Ensures only authorized users can interact with the bot.

Audio Handling – If it’s a voice message, the workflow retrieves and transcribes the recording.

AI Agent – Both transcribed voice or text are sent to the AI Agent powered by Google Gemini + Simple Memory.

Smart Actions – Based on the query, the AI can:

Read or create events in Google Calendar

Create notes in Notion

Send messages in Gmail

Reply in Telegram – The bot sends a response confirming the action or providing the requested information.
