  • Vector, not a raster guess

    Quantities come off the PDF's real linework.

  • Every item shows its source

    AI proposes with the line it read. It never prices.

  • Nothing moves without you

    No quantity issues and no money bills unapproved.

Three things, every job, without asking

Quantities off the drawing, a programme that knows its own float, and a money position that reconciles. Drawn below from one sample job so the numbers tie out across all three — the same way they do on yours.

Over-billed $57,634

Billed minus earned. Margin has faded 1.9 points since the bid — the reason is on the cost report, line by line.

Sample figures, shown so you can check the arithmetic: 62.6% complete is $1,312,000 ÷ $2,096,000; earned is $2,480,000 × 62.6%; the over-billing is $1,610,000$1,552,366. Nothing here is a customer’s job.

Your office work, lined up before you get to it.

It reads your drawings, specs, quotes, contracts and email, then lines up the work: quantities, submittals, RFIs, notice deadlines, draws. Every item shows the line it came from. Nothing moves money or goes out the door until you approve it. Built for specialty trades, residential and commercial GCs, public work, and developers.

From bid notice to paid draw

One job record from the first bid notice to the last holdback release — set up for a trade shop or a full GC.

Hire first. Desk second. You keep the rest.

Price it against the hire, not against other software. Takeoff starts against an estimator at about $6k a month loaded. The full office — four roles, about $24k a month loaded — opens once your team runs jobs on it every day. Paying annually saves two months.

The three questions, answered in public

Where does my data live?

Your own tenant, row-level security on every table, drawings in a private bucket that no public URL reaches.

numbers AI sets on its own
Models read and propose with a quote. Deterministic engines compute. You approve.

Every number traces back to the drawing.

Quantities come from exact linework and schedule counts, and a person approves them. AI reads your documents and shows where each item came from — it never sets an order quantity or a price on its own.
