Start sketching on a clean surface
Zero-latency infinite board. Pen, pencil, eraser, colour and dot grid. Private — runs entirely on your device.
Launch WhiteboardHow it works
Open the board and draw immediately. The surface is an infinite canvas — drag with the Hand tool or hold Space to pan, pinch or scroll to zoom. Every stroke is rendered as a vector so you can erase a whole stroke with a single swipe.
Pick Pen for bold marks, Pencil for fine lines, and Eraser for stroke-based removal. Adjust size with the slider and pick a colour from the palette or your own custom colour. The dot grid at 24 px gives a subtle drafting reference without interfering with sketches.
Your work is autosaved to local storage on this device. Share generates a short link like ?s=Ab12Cd3 — no long hash URLs. Recipients open the link and the drawing loads instantly. Export a PNG cropped to your drawing bounds at any time.

Frequently asked questions

Yes. Draw with finger or stylus, pan with two fingers and pinch to zoom. The canvas handles pointer events for Apple Pencil, Wacom and trackpad input.
Open the drawer and choose New Whiteboard to clear. Choose Export as PNG to download a tightly cropped image with your current background. Both respect your active zoom and background choice.
