Description
🎥 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
🧩 Flow Overview
| Step | Description |
|---|---|
| ✅ Form Trigger | User submits a YouTube video ID using an n8n form |
| 🔁 Set Node | Maps the YouTube video ID for use in the API request |
| 🌐 HTTP Request (External API) | Calls the YouTube Transcriptor AI API via RapidAPI to fetch transcript |
| 🧹 Formatter (Code Node) | Joins transcript lines into a readable text block |
| 🧠 AI Agent + Google Gemini (via Langchain) | Summarizes the full transcript into bullet points and tone |
| 🧽 Optimizer (Code Node) | Extracts just the summary from the AI response |
| 📝 Google Docs Node | Appends the clean summary to a shared Google Doc |
