Draft — not for construction approval unless checked by a qualified professional.

The problem

Measuring walls and counting boards by hand is slow, and generative image tools produce pictures, not measurements.

Our solution

Computer-vision segmentation (YOLO) finds walls, doors and windows; one known dimension calibrates the scale; geometry is cleaned up and turned into an elevation with dimension lines. Users correct the drawing in an SVG editor, and their corrections become training data.

  • Scale calibration from known dimensions
  • SVG correction editor
  • Exports to SVG, PDF, DXF and JSON
  • Every output clearly marked as a draft for professional checking

Result

MVP covering upload, background AI processing, elevation geometry, material estimates and CAD-style exports.
