Chalk Duster
Tip: use a finger or pen on a smart board. Extra touches are ignored so a resting palm will not draw. Everything past chalk lives in the Shapes, Board and Tools menus. Press Fullscreen for the whole display.

Frequently asked questions

Is it free and private?

Yes. It is free with no sign-up and runs entirely in your browser. Nothing you write is uploaded, and your boards stay on your device.

Does it work on a smart board or touch display?

Yes, it is built for touch. Write with a finger or a pen, and extra touches are ignored so a resting palm does not draw. Tap Fullscreen to fill the whole display.

What tools are inside the menus?

The Shapes menu has lines, arrows, rectangles, ellipses, triangles and a fill option. The Board menu holds backgrounds, guides, and add, duplicate, delete and clear. The Tools menu holds a timer, spotlight, screen shade, dice and insert image.

Can I save what I wrote?

Yes. Press Save to download the current board as a PNG image to share or print. You can keep several boards open and switch between them.

How do I erase?

Choose the Duster to rub out part of the board, or use Clear in the Board menu to wipe the whole board. Undo and Redo are there if you change your mind.
