Transform YouTube Transcripts to Content Assets with AI and Google Sheets

Description

Transform YouTube Transcripts to Content Assets with AI, Youtube-transcript.io and Google Sheets

For content creators, marketers, and video strategists who want to transform YouTube competitors' video transcripts into production-ready content assets using AI-powered automation.

Overview

This template demonstrates two approaches to YouTube transcript extraction and AI content generation: automated Google Sheets monitoring for batch processing, and direct webhook API calls for on-demand extraction. The workflow includes intelligent parsing, metadata extraction, and AI-powered content transformation.

Key Features

Dual Workflow Architecture
Google Sheets integration for automated monitoring and batch processing
Webhook endpoint for real-time API access and instant responses
Both paths share core extraction logic while serving different use cases

Smart YouTube Parsing
Extracts video IDs from multiple URL formats (youtube.com, youtu.be, embed)
Regex-based parsing handles edge cases reliably
Graceful error handling for invalid URLs

Rich Metadata Extraction
Video title, channel name, and publish date
Duration and category information
Transcript text with full timestamp data
Fallback handling for videos without transcripts

AI Content Generation
Transforms raw transcripts into structured content assets
Generates Veo3-optimized scripts (8-second scene format)
Creates SEO-optimized titles, thumbnail concepts, tags, descriptions
Includes virality optimization suggestions (hooks, CTAs)
Uses OpenRouter for flexible LLM selection

Structured Output Parsing
Custom code nodes parse AI responses into consistent formats
Organized by content type (Script, Titles, Thumbnails, Tags, etc.)
Ready for direct insertion into Google Sheets or API responses

Technical Implementation

Nodes Used
Google Sheets (Trigger & Operations)
Webhook (Trigger & Response)
HTTP Request (YouTube Transcript API)
Code (JavaScript for parsing)
LangChain LLM Chain (Content generation)
