🎥 YouTube Video Summarizer for Social Media

Turn any YouTube video into a short, structured summary using AI — perfect for content creators, marketers, or social media managers.


🔧 What We Built

We created a no-code automation in n8n that:

  • Accepts a YouTube Video ID via a form
  • Fetches the video transcript using an external API
  • Summarizes the transcript using AI (Google Gemini)
  • Automatically saves the summary to Google Docs for team use
