Offline Whiteboard
Sketch ideas locally with a canvas that never leaves your browser. Strokes autosave to this device, so you can revisit and export your boards any time.
Canvas workspace
Everything renders client-side and persists in local storage. Refresh without losing your notes or export a PNG snapshot when you’re done.

Offline usage
Collaboration is disabled in this version. If you need live sync, point the app at your own Yjs signalling server or export snapshots to share manually.
Strokes are stored in localStorage. Use your browser’s “Clear Data” or the button above to reset the board.
Workflow tips
- Duplicate the tab to compare alternate sketches side by side.
- Export PNG snapshots between iterations to track your progress.
- Pair with the Image Cropper or Filter Studio to polish drawings after export.
