Automate Video Creation from Voice Input with HeyGen & n8n


πŸ‘₯ Who is this for?

This workflow is ideal for:

  • Content creators who want to turn ideas into videos in minutes
  • Marketers managing multi-platform video campaigns
  • Agencies needing scalable video workflows for multiple clients
  • Entrepreneurs looking to automate social media presence

πŸ’‘ What problem is this workflow solving?

Creating and publishing videos across TikTok, YouTube, Instagram and more is:

  • Time-consuming (writing scripts, creating videos, uploading manually)
  • Inconsistent (different platforms, formats, captions)
  • Hard to scale without automation

This workflow solves it by turning a voice note into a complete AI video β€” scripted, generated, and published automatically.


βš™οΈ What this workflow does

  1. Capture idea via Telegram voice note
  2. Transcribe audio to text using OpenAI Whisper
  3. Generate script, title, and caption with GPT-5
  4. Create avatar video with HeyGen based on your script
  5. Save final video to Google Drive and log metadata in Google Sheets
  6. Upload video to Blotato
  7. Auto-publish to 9 platforms (TikTok, YouTube Shorts, Instagram, LinkedIn, Facebook, Twitter (X), Threads, Bluesky, Pinterest)
  8. Send Telegram notification once published

🧰 Setup

Before you start, you’ll need:

  1. βœ… A Telegram Bot connected to n8n
  2. πŸ”‘ An OpenAI API key (Whisper + GPT-5)
  3. 🎭 A HeyGen API key for avatar video generation
  4. πŸ“‚ Google Drive + Sheets integrations for storage & logs
  5. 🧩 A Blotato Pro account with API access enabled
  6. πŸ“¦ Verified Community Nodes enabled in n8n Admin Panel
  7. βš™οΈ Blotato node installed + credentials configured
  8. πŸ“„ A Google Sheet template to log titles, captions, and video links

πŸ› οΈ How to customize this workflow

  • Change prompts β†’ Adjust GPT-5 prompts to fit your tone or brand
  • Select avatars β†’ Configure HeyGen avatar and voice to match your style
  • Choose platforms β†’ Activate only TikTok, YouTube, Instagram, etc.
  • Add approvals β†’ Insert a Telegram or Slack approval step before publishing
  • Extend reporting β†’ Push analytics or engagement data into Sheets or Notion

This workflow transforms a simple voice message into a ready-to-publish viral video β€” fully automated, consistent, and scalable.
