Turns YouTube lectures into proper LaTeX course notes with a compiled PDF. You feed it a URL, it grabs the highest resolution video it can actually download, pulls subtitles, extracts the cover image and key frames, then writes structured Chinese teaching notes organized by pedagogical flow rather than subtitle order. For long videos it splits the work across parallel agents and integrates the output. The prompts emphasize deep explanations with motivation before formalism, figures everywhere they help, and a synthesis chapter at the end. It explicitly tells Claude to avoid vague phrasing and the overused "不是……而是……" contrast pattern. Useful if you're studying technical content in Chinese and want reference material that reads like a patient teacher wrote it, not like someone transcribed a video.
