Your board is saved only in this browser (localStorage) and never uploaded. Pen, shapes, notes & text all live as editable objects.

A real whiteboard that stays on your machine

Every stroke, shape, arrow and sticky note is kept as an editable object, pick the Select tool to move or delete anything, and undo/redo as much as you like. The board auto-saves to your browser so a reload won't lose your work, and you can export it as a crisp PNG for slides or as JSON to reopen later. No charting or drawing library, no server, just a canvas painted locally. Completely free, completely private, works offline.
