Blueprint Reader

Frame takeoff from a photo

Snap your blueprint. We straighten it, find the walls, doors & windows, read the dimensions, and build your lumber list.

For best results

  • Lay the sheet flat, shoot straight down in good light
  • Get the whole sheet in frame with a little margin
  • Hold still — blur kills the line detection
v1 runs 100% on your phone — no signal needed on site.
v2 will add cloud AI detection for hand-marked prints.

Straighten the sheet

We found the paper edges. Drag the blue dots to fine-tune, then tap Apply.
