Whiteboard

Sketch ideas, drop sticky notes and connect shapes on a canvas that lives entirely on your device — nothing is ever uploaded.

0 objects Del remove selected Ctrl+Z undo

🔒 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.
