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 standard YouTube URL, short link, shorts, embeds, live links, or raw video ID, with optional timestamps and language fallback chains. - Content Transformation: Convert transcripts into chapters, summaries, chapter summaries, Twitter/X threads, blog posts, or timestamped quotes. - Long Video Handling: Automatically chunk transcripts exceeding ~50K characters with overlapping segments, summarize each chunk, and merge results. - Use Case: A user shares a 45-minute conference talk link and asks for a Twitter thread; the Skill fetches the transcript with timestamps, identifies key insights, and outputs numbered posts under 280 characters each. ## Quick Start Summarize this YouTube video into a chapter list with timestamps: https://youtube.com/watch?v=VIDEO_ID
