Content generation (Heygen & human in the loop)
This workflow is built as a ready-to-use n8n automation for AI-driven content creation. It can generate written posts, create AI avatar videos using HeyGen, and publish content automatically to platforms like LinkedIn, YouTube, Instagram Reels, and TikTok.
You can use the templates exactly as they are, or customize them to match your own style, niche, or publishing routine.
What You Need to Customize
Before running the workflow, make sure to update the following:
API Keys
Add your OpenAI key, HeyGen API key, and any platform-specific tokens (LinkedIn, YouTube, Instagram/TikTok if applicable).
Webhook URLs
If the workflow uses a HeyGen callback, replace the placeholder webhook with your live one.
Brand Voice / Prompts
Adjust the prompts inside the workflow so the AI generates content in your tone, niche, and structure.
Publishing Credentials
Connect your social accounts in n8n (OAuth setup). This enables auto-posting.
