YouTube Video Summarizer & GPT-4o-mini Chat via Telegram

This n8n workflow enables seamless summarization of YouTube videos and AI-powered conversations about the content directly through Telegram. Users send a YouTube URL via Telegram or webhook, triggering transcript extraction using the custom youtubeTranscripter node. The full transcript is concatenated and saved to Google Docs for persistent storage.

Next, GPT-4o-mini generates a structured summary including an overview, key moments, and instructions if relevant, which is instantly sent back to the user. For interactivity, users can ask follow-up questions in the same Telegram chat. The workflow retrieves the transcript from Google Docs, feeds it to GPT-4o-mini for precise, context-based answers, and responds in real-time.

Benefits include massive time savings for researchers, content creators, educators, and teams analyzing videos—no manual transcription or note-taking required. Use cases: Quick video digests for busy professionals, student study aids, marketing teams extracting insights from competitor videos, or podcast/video review automation. Requires installing the youtubeTranscripter community node.
