Khan Explainer

Khan Explainer: Claude Code skill that generates Khan Academy style animated chalkboard and whiteboard MP4 explainer videos from text descriptions.

Khan Explainer is a Claude Code skill that turns plain English descriptions into Khan Academy style explainer videos. Users describe a concept, Claude generates a scene file organized by narrative beats, and local tools render the final MP4. The animation engine uses spoken audio duration to drive the drawing clock, ensuring strokes fit the exact timing of the voice. It runs locally using an HTML canvas, Playwright, ffmpeg, and macOS's built-in text-to-speech, with optional integrations for ElevenLabs, Kokoro TTS, and faster-whisper. It supports chalkboard or whiteboard visuals in landscape or vertical layouts, as well as UI screenshot overlays and real-audio clips.
