AI-Powered YouTube Chapter Generator

This n8n workflow revolutionizes how you add chapters to your YouTube videos. By integrating with YouTube's caption service and powerful AI models, it automates the laborious task of transcribing and segmenting your video content into easily navigable chapters, improving viewer experience and SEO.

Key Features

  • Automated Caption Extraction: Effortlessly pulls SRT captions directly from your YouTube videos.
  • Intelligent Chapter Generation: Leverages cutting-edge AI (Google Gemini via LangChain) to analyze video content and identify key segments.
  • Accurate Timestamping: Generates precise time-stamped chapters based on your video's transcript.
  • Seamless YouTube Description Update: Automatically inserts generated chapters into your video's description, saving valuable manual effort.
  • Enhanced Video SEO & Engagement: Significantly improves video discoverability and allows viewers to quickly navigate to relevant sections.

How It Works

The workflow initiates by receiving a YouTube Video ID. It then efficiently fetches the video's existing metadata and extracts its captions in SRT format. These raw captions are then passed to an advanced AI model (Google Gemini), orchestrated by LangChain, which intelligently processes the transcript to identify key topics and generate accurate time-stamped chapters. Finally, these newly created chapters are automatically appended to the video's description on YouTube, making your content more accessible and engaging for your audience.
