AI Video Generation & Auto Publishing to TikTok, IG, YouTube (n8n Workflow)

Create, render, and publish short-form AI videos daily—without touching a single tool. This fully automated n8n workflow turns content ideas into engaging POV-style videos and distributes them across 5+ platforms including TikTok, Instagram, YouTube, Facebook, and LinkedIn.

It pulls content ideas from Google Sheets, generates captions, visuals, and voiceovers using AI (OpenAI + PiAPI + ElevenLabs), assembles everything into a complete video with Creatomate, and posts it automatically with relevant descriptions. All progress and metrics are logged in your Google Sheet, and you get notified via Discord once the job is done.
