About This Workflow
Unlock the power of AI to effortlessly digest long YouTube videos. This n8n workflow automates the entire process of fetching video transcripts via SearchApi, intelligently concatenating them, and then feeding them into an advanced AI summarization chain powered by OpenAI's gpt-4o-mini. Perfect for researchers, content creators, marketers, or anyone needing quick insights without watching full videos. It handles large transcripts by recursively splitting text before summarization, ensuring efficient and accurate results. Simply provide a YouTube video ID, and let n8n deliver a concise summary directly to you.
