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 the transcript directly and transforms it into structured written content. ## Core Features & Use Cases - Transcript Extraction: Fetch transcripts from any YouTube URL format (watch links, youtu.be, shorts, embeds, live, or raw video IDs) with optional timestamps and language selection. - Content Transformation: Convert transcripts into chapters, summaries, chapter summaries, Twitter/X threads, blog posts, or timestamped quotes. - Long Video Handling: Automatically chunk transcripts over 50K characters with overlap, summarize each chunk, and merge results. - Use Case: A user shares a 45-minute conference talk link and asks for a summary plus a Twitter thread; the Skill fetches the transcript, validates it, and produces both outputs with accurate timestamps. ## Quick Start Summarize this YouTube video and give me a chapter breakdown: https://youtube.com/watch?v=VIDEO_ID
