YouTube Curator AI Agent (n8n Workflow) — Automated Viral Video Research

The YouTube Curator AI Agent is a fully automated n8n workflow designed to scan YouTube weekly, fetch trending videos in your niche, analyze their engagement performance, calculate growth metrics, save everything to Google Sheets, and send AI-generated content inspiration directly to Slack.

This system helps you create winning YouTube videos without manual research, removing hours of scrolling and guessing. Every week, it delivers a curated list of high-performing videos—plus expert AI insights telling you exactly why they work and how you can recreate them.

This automation is essential for creators, YouTube automation channels, marketing teams, and agencies wanting a data-driven, consistent inspiration engine.

WHAT THIS AUTOMATION DOES (STEP BY STEP)

Based on the uploaded automation:

1. Weekly Auto-Searches YouTube for High-Performing Videos

The workflow triggers every week using the n8n Schedule node, then:

Searches YouTube for your chosen keyword Filters by videos uploaded in the last 7 days Retrieves titles, descriptions, URLs, thumbnails, publish date Pulls complete stats (views, likes, comments)

This ensures you always get the freshest and most relevant content trends.

2. Calculates Full Engagement Metrics Automatically

Using the built-in Code node, the workflow calculates:

Like Rate (%): likes ÷ views Comment Rate (%): comments ÷ views Views per Hour: growth speed Rating Filters: quality thresholds

These metrics reveal what content is actually working, not just what has views.

3. Filters Only Top-Performing Videos

The automation automatically discards weak videos and only stores:

LikeRate > 7% CommentRate > 0.15% Views > 1,500 (Second filter) LikeRate > 8.8%

You get only the real winners — no noise, no junk.

4. Saves Everything into Google Sheets

Every selected video is added to a Google Sheet with:

Title Video ID Clean description URL Publish date Views, likes, comments LikeRate, commentRate, views/hour Automatically generated “added_date”

This becomes your organized YouTube research database.

5. AI Generates Advanced Content Insights

The workflow uses GPT-4o-mini to generate:

Why the video works What makes it engaging How to improve it A new title idea A content structure you can create today

This removes the guesswork by giving you high-level strategy + actionable ideas.

6. Sends a Ready-to-Use Inspiration Message to Slack

The system sends a beautifully formatted message to Slack including:

Video title Shortened description Growth metrics AI insights New title idea “How to recreate this” outline

This becomes your weekly inspiration feed.
