draw-json demo

Click DRAW in the bottom-right corner, sketch anywhere on the page, then hit COPY JSON and paste the result into an AI agent chat.

A card to circle

Circle this card slowly and the circle should stay a circle: slow, deliberate strokes are only lightly smoothed.

Another card

Scribble over this one fast: fast strokes get the full jitter filter.

Undo while drawing with cmd/ctrl+Z. Clear everything with the × button. Drawings persist per page in localStorage.
