01How it works
No typing, no wording: you take the photo, ZeroSnag does the rest. Click through the steps here or choose an example photo.
Take a photo with your phone, in the app or in the browser. You can also upload site-walk photos later on your PC.
Capture the defect02What the AI detects
From shell to handover: ZeroSnag detects defects on site photos, locates them in the image and describes them the way they belong in the report.

Power and data cables are bundled directly, the separation distance is missing.

Several electrical cables run without clearance along the insulated plumbing and heating pipes.

There is a gap of about 8–10 mm between collar and wall; 5 mm is permitted.

A heating pipe lies directly on cables and ventilation duct and is strapped down with perforated tape.

The left support foot rests on loose pieces of wood; the inclined hoist may tip over.

A fine crack runs diagonally upwards from the window corner.
