Description

Who’s it for

For makers, founders, and productivity nerds who want to listen to their inbox instead of reading it. No servers, no hosting — all done with n8n, a Telegram bot, and AI/ML API (LLM + TTS).

What it does / How it works

This workflow listens for new Gmail emails, extracts the sender, subject, date, and snippet, generates a 2–3 sentence natural summary using GPT-5 via AI/ML API, then converts the text into a lifelike voice message using Inworld TTS-1-Max. The final audio file is downloaded and instantly delivered to your Telegram via a bot.

A separate auxiliary flow captures your Telegram chat_id once, stores it in a Data Table, and the main flow reuses it every time — no hardcoding required.

High-level flow:

1. Gmail Trigger detects new incoming email
2. Code node builds a clean emailData block
3. AI/ML API (GPT-5) generates a natural spoken summary
4. AI/ML API (Inworld TTS-1-Max) converts summary → voice
5. Audio file is downloaded
6. Voice message is sent to the same Telegram chat

Requirements

• A working n8n instance (self-hosted or cloud)

• Gmail OAuth2 credentials

• Telegram bot token from @BotFather

• AI/ML API key

  • Base URL: https://api.aimlapi.com/v1
  • Supports GPT-5 and Inworld TTS-1-Max

Set up steps

• Create a Telegram bot via @BotFather and add Telegram API credentials in n8n
• Create an AI/ML API credential using your API key
• Add Gmail OAuth2 credentials for inbox access
• Import the workflow JSON
• Open nodes and attach the correct credentials (no hardcoded tokens inside nodes)
• Run the Telegram Trigger once and send any message to your bot — this saves your chat_id
• Activate your workflow and receive your first voice-summary

How to customize

• Replace GPT-5 with another LLM from AI/ML API (same schema)
• Change prompt style: tone, structure, language, or verbosity
• Add language selection or multi-voice support
• Add filters (e.g., only important emails, only starred emails)
• Log all activity to Google Sheets or a database
• Add IF conditions: voice only during certain hours, weekday vs weekend rules
• Add rate-limits or user allowlists
• Change the voice model for different notification styles: corporate, friendly, narrator
