Your drafts, your browser
No account needed to start. Your work stays in your browser. Sign in only when you want a server copy or a public layout.
Share when you want
Use the Gallery only if you want a public copy. Local maps remain local.
How it works
- Create a local map (or duplicate a draft) from inside the Designer.
- Draw your plan with rectangles, circles, lines and the eraser tool.
- Export to ASCII for More Planning, or import an existing layout to edit.
