Generate YouTube Video Ideas from Comments with GPT-4o-mini and Google Sheets

#Analyse YouTube Comments via AI Agent and Create Video Topics

Description Identifying what your audience wants can be a manual and time-consuming process. This workflow automates your content research by analyzing comments from your latest YouTube videos using an AI Agent. Every week, it fetches feedback, stores it in Google Sheets for backup, and uses OpenAI to suggest the TOP 5 SEO-optimized video topics based on real viewer requests.

The final content strategy is delivered directly to your Gmail inbox, allowing you to focus on creating rather than researching.

What it Does Weekly Trigger:* The workflow starts automatically every Friday (customizable) via the Schedule Trigger*. Fetches Video Data:** It pulls the latest 5 videos from your specified YouTube playlist. Retrieves Comments:* Uses the YouTube API (HTTP Request)* to fetch up to 100 comment threads per video. Data Archiving:* All retrieved comments are saved into a Google Sheet*, ensuring you have a permanent backup of audience feedback. AI Analysis:* A JavaScript node formats the comments and passes them to an AI Agent. Powered by OpenAI (GPT-4o-mini), the agent identifies recurring themes and requests. Structured Output: The Output Parser ensures the AI provides exactly 5 video titles in a clean, professional format. Email Delivery: The Gmail node* sends a summary of the suggested content plan directly to your inbox.
