Automate YouTube Chapters & Posts with AI-Powered n8n Workflow

Transform Long YouTube Videos into Professional Chapters and Community Posts with One Click

This AI-powered n8n workflow automatically generates YouTube chapters and community posts from any tutorial or how-to video URL. Simply submit your video link with a section search query, and watch as the workflow finds key moments, creates formatted timestamps, writes descriptions, and delivers everything ready to paste directly into YouTube.

What This Workflow Does

• Finds up to 15 section moments per video — WayinVideo's Find Moments API scans your entire tutorial based on your search query and returns timestamped moments with titles and descriptions
• Sorts all moments chronologically — All returned moments are automatically sorted by start time before processing to ensure your chapter list displays in correct viewing order
• Generates formatted chapter timestamps — GPT-4o-mini creates clean 3-6 word chapter titles for every moment with exact MM:SS values, always starting with 0:00 Introduction
• Writes professional content — Automatically generates a 3-4 sentence video description block and a 100-150 word YouTube Community post with full timestamp list embedded
• Saves to Google Sheets — Everything is organized in one row with Status set to "Ready" for immediate copy-paste into YouTube

Use Cases

• YouTube creators publishing long-form tutorial content who need professional chapters without manual video scrubbing
• Educational content teams managing multiple how-to videos and course materials
• Content marketers creating community engagement posts with detailed video breakdowns
• Training departments converting lengthy instructional videos into easily navigable content
