YouTube tutorials, reconstructed

Watch the tutorial. Open the editor when you want the code.

The video is just YouTube. The bar at the bottom — or the E key — opens the file on screen beside the still-playing video. Edit it. Run JS or Python in this tab. Esc goes back. No API key. Your browser caches a compact copy in this tab and reads frames here; closing the tab frees that space.

Instant demos — no API key. Any other link caches on this device, in this tab.
