What problem does it solve? Manually watching long YouTube videos to capture key points is time-consuming, and repurposing video content into written formats requires tedious transcription work. This Skill fetches video transcripts programmatically and transforms them into structured written content. ## Core Features & Use Cases - Transcript Extraction: Fetch transcripts from any standard YouTube URL, short link, shorts, embeds, or raw video ID, with language fallback support. - Multiple Output Formats: Convert transcripts into timestamped chapters, summaries, chapter summaries, Twitter/X threads, blog posts, or notable quotes. - Long Video Handling: Automatically chunk transcripts exceeding ~50K characters with overlapping segments before merging summaries. - Use Case: A content creator shares a 45-minute conference talk URL and asks for a summary plus a Twitter thread. The Skill fetches the transcript, validates it, and produces both formats with accurate timestamps. ## Quick Start Summarize this YouTube video and give me timestamped chapters: https://youtube.com/watch?v=VIDEO_ID
