Upload or capture an image of a concrete surface. CRACKSCAN segments and
classifies surface cracks, then assembles a review-ready report.

Included in the report.
Print a scale marker for real millimeter measurements — place it flat next to the crack, in the same photo. Optional; without it, measurements are pixel-only.

Analyzing surface…
Along crack — shadow-based relief, read directly from the photo’s own pixel darkness inside the crack (darker = less light reached that point = more recessed). Shown with brighter/yellow = more recessed, dark purple = shallower. Can be thrown off by dirt, uneven lighting, or crack width. Relative, visual — not a physical or metric measurement.
Width along the crack, colored on a relative scale (this crack's own thinnest-to-thickest range).

Affected area
Severity (BRE Digest 251) is based on width alone — the standard notes several cracks, position near openings, or other structural signs can indicate a higher category. Not a substitute for a licensed structural engineer.
AI assessment
Get help deciding what to do: risk level, recommended action, likely causes and what to check on site. Sends the photo and the results above to an external AI model (via OpenRouter). Your description, if entered, is included.
Asking the AI model… this can take up to a minute.
Click two points along the crack. CRACKSCAN computes the angle of
the line through them to the horizontal (0–180°, same
convention as the measurements table).
