About ClkBoard

ClkBoard is a chalkboard you draw on like real chalk: in the browser, or as one portable file that works offline. Share a board live with a code, a link or a QR code; everyone sees each other's chalk as it is written, with a name at every pen, and the host can lock the board. Tidy straightens what you draw. Boards are kept as strokes, so nothing is ever lost to pixels. Free, no account.
