A service that grew out of an engineer’s frustration

Quantity take-off is one of the least glamorous and yet most expensive jobs in construction. On an average family house you read off wall lengths, deduct openings, total up areas — and then repeat all of it for every material category. It takes hours, typically in the evening or at the weekend, and a single lapse of attention runs through the whole calculation.

The error punishes you in both directions, too. Work with less material than reality and the difference comes out of the contractor’s pocket. Work with more and the quote is more expensive than the competition’s. What is at stake is not theoretical accuracy but real money — while the work itself is purely mechanical.

Hence the question: if the data is already there on the drawing, why does somebody have to type it out by hand for the third time?

MűLeÍr is built by Németh László. He graduated as a mechanical engineer, then qualified as a building energy performance assessor with the Hungarian Chamber of Engineers, and went on to earn a postgraduate degree in building energy engineering at the University of Pécs.

The practical side of that career matters at least as much. Working as an engineer at a main contractor, he produced dozens of architectural bills of quantities together with the take-offs behind them, and also worked on architectural design and technical drawing. Later, while running his own contracting team, the daily job was the technical preparation of projects, quotations and quantity calculations, and preparing decisions for clients.

He has been working with building energy performance for more than ten years, meeting several hundred clients along the way — for new builds, extensions and the refurbishment of existing homes alike. Those conversations are what made it clear where the process gets stuck and what is genuinely needed. MűLeÍr is the first step of that: making material take-off and bill-of-quantities work easier.

Uploaded PDF drawings are processed by automated data extraction: the system reads the rooms, dimensions, doors and windows and wall structures, and calculates material quantities from those in 10 categories at present. The calculation is not a lumped estimate: it gives items broken down by pieces, square metres, cubic metres, linear metres and kilograms, including the usual trade allowances — overlap and cutting waste among them.

Automatic recognition is not infallible, and we do not claim it is. Accuracy depends on the quality of the drawing: it works more reliably from a CAD-drawn, dimensioned plan than from a scanned, hand-annotated sheet. That is exactly why there is a review screen in the middle of the process, where every extracted value can be corrected and the calculation re-runs with your corrections. So the end result is not down to a black box — you see and approve the data the report is built from.

The system also learns from corrections: the corrected data of paid or unlocked projects may become a training example once a member of our team approves it, so recognition of Hungarian drawings keeps getting more accurate. If you do not want this, you can object as described in the privacy policy.

Uploaded drawings are stored encrypted within the European Union (Supabase, Frankfurt region). For processing, the drawing is sent for automated data extraction (Anthropic), and payment is handled by Stripe. We do not sell or publish your drawings. You can delete a project in your account at any time — together with the drawings, the report and any training example made from it; a project created without signing in is deleted automatically 30 days after creation without payment, or 1 year after payment.

The providers involved in processing, the place of storage and the legal basis of data processing are listed individually in our privacy policy.
