Cloneware: apps for Claude Artifacts and ChatGPT Sites
Sketchroom
A hand-drawn whiteboard your team draws on together, with live cursors and connectors.
A shared sketching board for quick diagrams, flows and rough ideas. Everyone who opens the Artifact draws on the same board. You see the others' cursors, names and selections, and you see their strokes while they draw.
What you can draw
Rectangles, diamonds, ellipses, lines, arrows, pen strokes and text, with a hand-drawn look
Stroke colour, background, fill style (hachure, cross-hatch, solid), stroke width, sloppiness and opacity
Arrows and lines that attach to shapes: drag from one shape to another, and the line follows when you move or resize a shape
Editing
Select, select an area, move, resize, duplicate, Alt-drag to copy, copy and paste, layer order
Undo and redo
Pan with Space-drag or the scroll wheel, zoom with Ctrl+scroll or a pinch, zoom to fit
Single-key tools: R, D, O, A, L, P, T, E, and Q to keep the tool on
Sharing and export
The board saves in the Artifact's shared storage, so it is the same for everyone and survives a reload
Viewers with view-only access see a read-only board; give Contributor access to let people draw
Export the board as PNG or SVG
How to start
Publish the file as a Claude Artifact with the declared capabilities, then share it with your team. The board opens empty with a short list of shortcuts.
