AI-Powered YouTube Video Summarization

This powerful n8n workflow automatically processes YouTube videos to extract their transcripts, summarize them using advanced AI, and deliver structured insights. Ideal for content creators, researchers, students, or anyone needing quick, deep dives into video content without manual effort.

Key Features

  • **Automated Transcript Extraction**: Effortlessly pull full transcripts from any public YouTube video.
  • **Intelligent AI Summarization**: Leverage gpt-4o-mini via LangChain to generate concise, structured summaries.
  • **Structured Insights**: Summaries are formatted with main topics (H2), bullet points, bolded key terms, and organized by definition, characteristics, implementation, and advantages/disadvantages.
  • **Instant Webhook Response**: Receive the full summary and video metadata directly via an API call.
  • **Telegram Notifications**: Get instant alerts with video title and URL upon completion.

How It Works

The workflow begins when a YouTube video URL is sent to a Webhook. It then extracts the video ID, fetches video metadata using the YouTube node, and retrieves the complete YouTube Transcript. This transcript is concatenated and fed into a LangChain LLM (gpt-4o-mini) which applies a detailed prompt to create a highly structured, analytical summary. Finally, the generated summary, along with original video details, is returned as a Webhook response and simultaneously sent as a notification to Telegram.
