Diah AR Sketch
Marker-based tracing
1
Choose your reference
JPG, PNG or WEBP — the image you'll trace onto your surface.
Tap to add reference
From your photos or files
2
Alignment method
Free overlay floats the reference over your camera — best for large walls and moving up & down, with no marker to lose. Marker tracking locks the overlay to a printed marker.

Choose AR mode
Switch any time while tracing.
Live AR needs camera access over HTTPS and a printed marker.
Tracking quality depends on lighting and a flat, fully-visible marker.

How the marker works
Diah Sketch tracks a printed marker to lock your reference onto the paper — your artwork stays clear because the overlay sits beside the marker.
