Latenode

Streamline your digital life with voice-activated AI

This template listens for Telegram messages, transcribes voice notes with Latenode speech-to-text, and asks ChatGPT what to do.

It then lists or updates Google Calendar, Gmail, and Google Tasks, and replies on Telegram. Connect Telegram, Google Calendar, Gmail, and Google Tasks. Put the bot token on the Telegram connection. ChatGPT and speech-to-text are Latenode AI steps, so you do not paste an OpenAI key.

How Latenode estimates time and cost

Latenode bills workflow runtime in CPU seconds. The first 10,000 CPU seconds are free each month, then usage follows pay-as-you-go CPU-second pricing. Plug-and-Play (PnP) AI nodes are billed separately—each PnP token is $1 USD, charged pay-as-you-go at vendor cost plus a small processing fee, with no API keys required.

How it works

1
Trigger

Listen for Telegram messages

The scenario starts when the bot receives a text or voice message.

2
Action

Transcribe voice

If the message is a voice note, Latenode downloads the file and turns it into text with speech-to-text.

3
AI

Decide the action

ChatGPT reads the text and chooses calendar, mail, or tasks.

4
Action

Read or update Google

The scenario lists upcoming events, finds unread Gmail, or creates a Google Task.

5
Action

Reply on Telegram

JavaScript builds a short summary and Telegram sends it back to you.

Setup guide

1

Connect Telegram

Add a Telegram connection with your bot token. Add the bot to the private chat you will message.

2

Connect Google Calendar, Gmail, and Google Tasks

Add those three connections and grant read access. Grant write access if you want ChatGPT to create events or tasks.

3

Wire speech-to-text and ChatGPT

For voice notes, download the Telegram attachment and transcribe with Latenode speech-to-text. Send the text to ChatGPT to choose calendar, mail, or tasks. Those AI steps are Latenode nodes.

4

Act and reply

List events, find unread mail, or create a task from the ChatGPT intent. Summarize the result in JavaScript and send it back on Telegram.

Requirements

A Telegram bot token stored on the Telegram connection
Google Calendar, Gmail, and Google Tasks connections in Latenode
A private chat where you message the bot
