Individual skill
khan-explainer
Use when the user wants a Khan Academy style explainer video, a blackboard or whiteboard lesson, a hand-drawn chalk-talk animation, a short narrated video that teaches a concept ("explain X in a video", "explainer video", "teach X in 30 seconds"), or a tutorial that draws hand-written arrows, circles and captions over product screenshots ("draw over the UI", "annotated walkthrough"), or clips cut from a YouTube video or podcast where the speaker's real audio plays under a blackboard drawn to it ("khanify this video", "clip this with the Khan visual"), especially when it must be free, local, and use no paid APIs or keys. macOS only.

# Khan Explainer
A pen draws while a voice explains. Three modes, one renderer:
- **Blackboard lesson.** A diagram drawn on a black board, Khan Academy style.
- **Draw-over-UI tutorial.** Arrows, circles and numbered captions drawn over product screenshots.
- **Real-audio clip.** A real person's voice, cut from a video, with the board drawn to their words. See "Real-audio clips".
One scene file in, one MP4 out, in seconds. Free and local: HTML canvas, Playwright, macOS `say`, ffmpeg. No keys.
Every mode renders as chalk on a blackboard or marker on a whiteboard, landscape or vertical.
