Who it is forA teacher, course creator or developer who needs a short explainer on a concept and has no video editor.

The problemProducing a whiteboard-style explainer normally means recording, drawing and editing by hand.

The outcomeAn MP4 of a diagram drawn stroke by stroke while a voice explains it, plus a contact sheet of every beat.

What you need first

  • macOS
  • Node 20 or newer
  • ffmpeg (install with brew install ffmpeg)
  • Claude Code, since the repo installs as a Claude Code skill

Steps

  1. Install ffmpeg on macOS with brew install ffmpeg.
  2. Clone the skill into Claude Code's skills folder with git clone https://github.com/haiderfarooq3/khan-explainer ~/.claude/skills/khan-explainer.
  3. Install dependencies with cd ~/.claude/skills/khan-explainer/scripts && npm install && npx playwright install chromium.
  4. Ask Claude Code: Make a 30-second Khan-style explainer on <topic>.
  5. Open the MP4 and the contact sheet path that the render prints, and check the layout on each beat.

Prompt for your agent

Using the khan-explainer skill in ~/.claude/skills/khan-explainer, write a 30-second Khan-style explainer scene about <topic> and render it to an MP4. Confirm the render prints a contact sheet path and that the MP4 plays with narration and drawing in sync.

Caveat. The skill's built-in voice is the macOS say voice, so the narration sounds like a system voice unless you add an optional voice.
