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 automatically and transforms them into structured written content. ## Core Features & Use Cases - Transcript Extraction: Fetch transcripts from any YouTube URL format (watch links, youtu.be short links, shorts, embeds, live links, or raw video IDs) 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 summary plus a Twitter thread. The Skill fetches the transcript, generates a concise overview, and produces a numbered thread of posts under 280 characters each. ## Quick Start Summarize this YouTube video and turn it into a Twitter thread: https://youtube.com/watch?v=VIDEO_ID
