Kotelys
Kotelys is designed by a quantity surveyor who runs an engineering office in the building trade. His everyday work: opening architects' PDF drawings, taking off lengths, areas and counts, deducting openings, then passing accurate quantities on to the estimating team.
Kotelys grew out of that work. It does not try to do everything: it measures on the drawing, sorts the quantities and produces reports that can be checked line by line, with no training course to follow.
How it moves forward
Every feature is tried on real take-offs before it is released. Beta testers, all of them construction professionals, say what is missing and what gets in their way; their feedback shapes what comes next.
Your projects stay on your computer, in a file that belongs to you and that every new version can open.
