How it works

  1. Pick a direction → (horizontal) or ↓ (vertical). Press Space to flip.
  2. Click a shape button — or hit 1=rect, 2=ellipse, 3=diamond, 4=arrow, 5=dotted arrow — to drop it next to the last one.
  3. The new shape auto-focuses for typing a label. Hit Enter to save (Enter on empty input just dismisses).
  4. Click any shape, or use ← → ↑ ↓ to move between shapes; Enter to edit, Delete or Backspace to remove. Backspace with no focus removes the last one.
  5. Share the URL with anyone — they see your edits live. Diagrams self-delete after 7 days.
