🧾 What this workflow does

This automation turns a Telegram voice or text message into a high-quality LinkedIn post using OpenAI’s Whisper, Dumpling AI and GPT-4, and then repurposes that same message into a content idea with visual inspiration using Dumpling AI. All outputs are saved to Airtable for review, approval, and scheduling.

👤 Who is this for

  • Founders or creators sharing ideas while walking or multitasking
  • Content teams turning voice memos into carousel content
  • Personal brands posting on LinkedIn with minimal manual work
  • Virtual assistants or SMMs handling voice-driven content tasks

⚙️ How to set up

✅ Requirements

You’ll need active accounts for:

  • Telegram Bot (via n8n’s Telegram Trigger node)
  • OpenAI (for Whisper and GPT-4)
  • Dumpling AI (to search Google and create Image)
  • Airtable (to log your posts)

In Airtable, create a table with the following fields:

  • Ideas (Single line text)
  • Context (Long text)
  • Image URL (URL)

🔧 Setup steps

  1. Set up your Telegram bot

    • Use BotFather to create a bot and get your token
    • Add the bot to a private group or channel

  2. Connect all credentials in n8n

    • Telegram Trigger (Bot Token)
    • OpenAI (for Whisper + GPT-4)
    • Dumpling AI (HTTP Auth)
    • Airtable (OAuth or Personal Token)

  3. Update node parameters

    • In the Telegram Trigger node, specify your bot and listening chat
    • In the HTTP node for Dumpling AI, add your API key via header
    • In Airtable nodes, map to your base and table correctly

  4. Optional prompt customization

    • In the GPT-4 node, you can update the prompt for tone, formatting, or CTA style

  5. Optional: Adjust the Dumpling AI prompt to suit your niche (e.g., health, tech, finance).

🧠 How it works

  1. The Telegram bot receives a voice message.
  2. Whisper transcribes the voice into clean text.
  3. GPT-4 formats the text into a polished LinkedIn post.
  4. Dumpling AI:
    • Generates a short-form content idea from the transcript.
    • Creates a branded image prompt and renders a matching image.
  5. The full set of outputs (text, idea, image) is saved to Airtable.
  6. You can now review and schedule the post manually or via another automation.

🛠️ Customization ideas

  • Swap Telegram for WhatsApp or voice memos via Google Drive
  • Add moderation or approval steps before saving to Airtable
  • Send the LinkedIn post directly to Buffer or Hootsuite for auto-posting
  • Generate post captions or hashtags using GPT-4 before publishing
  • Extend the workflow to auto-create carousel slides from the content idea

This workflow makes it easy to share your voice with your audience — literally. Whether you're walking, thinking out loud, or sending team updates, this automation turns your spoken ideas into professional content, ready to post or polish.
