Read the drawings once. Cite the code every time. Construction AI for general contractors, estimators, and tender teams, from $49 a month.

Upload the DWG itself — not a PDF export — and get back every conflict, gap, and missing dimension, each one carrying the clause it came from.

04 — The suite

FIVE PROGRAMS.
ONE JOB, END TO END.

Five finished programs, opened in a browser tab — from $49 a month, nothing to install. Take the one that prices a bid, add the takeoff that feeds it, or run a job end to end with nothing retyped. All eight — these five and the post-award suite — on Pro, $249/mo →

Each stage hands the next one its numbers. The takeoff becomes the estimate; the estimate becomes the levelling sheet; the awarded scope becomes what ScopeGuard defends — nothing retyped between them.

01 · Drawings in Free live demo

BLUEPRINT AUDITOR

$99/mo · Field plan

Measures a 400-sheet drawing set while you eat lunch, then flags every place the sheets contradict each other.

ReplacesTwo estimators, a scale rule and three evenings of highlighting per tender.

  • Quantities measured straight off the PDF — concrete, block, steel, finishes
  • Catches a sleeve that never made it into the structural slab, before the pour
  • Checks the drawings against the code that governs your site, clause cited
  • Writes the RFI, deficiency and change-order lists for you
  • Trade engines — electrical circuit loading and concrete quantities, with three more trades in development
02 · Spec review New

SPECCHECKER

$249/mo · Pro plan

Catches the spec calling for 4-hour rated assemblies while the drawings show 2-hour — then writes the RFI.

ReplacesThe spec read-through nobody has time for, and the change order it turns into.

  • 27 measurable properties across 39 named assemblies — ratings, R-values, thicknesses
  • Every disagreement quoted twice: their clause, your sheet
  • Tells you which material orders to hold before the truck is loaded
  • Drafts the RFI, one letter per spec section
03 · The bid

AI ESTIMATOR

$49/mo · Solo plan

Turns the takeoff into a priced bid you can defend line by line — with the walk-away number attached.

ReplacesThe bid-day spreadsheet with last year's rates and a contingency picked by feel.

  • 57 assemblies across 20 CSI divisions, priced from a dated rate table
  • 27 risk rules → a contingency with a written reason beside it
  • Permits, development charges and taxes for your jurisdiction
  • Margin ladder with win probability from your own past bids
  • Concrete/structural volumes checked against your geotech report's bearing capacity
04 · Sub quotes New

BID LEVELER

$249/mo · Pro plan

Levels a dozen sub quotes onto one scope and shows you that the low bid is low because it excluded the hoisting.

ReplacesThe levelling spreadsheet built from scratch, at midnight, the day before award.

  • 155 scope elements across 15 trade packages, quote by quote
  • Gaps priced from what the other bidders carried, not from a percentage
  • Every adjustment prints the basis it used
  • Excel matrix, award recommendation and clarification letters
05 · Buyout

SCOPEGUARD

$249/mo · Pro plan

Flags when two trades are both carrying the same exclusion — and prices the scope that nobody carried at all.

ReplacesFinding the hole in the buyout when the invoice arrives, not when you can still argue.

  • 215 master scope requirements checked across 20 trade packages
  • Every finding cited to your clause and their page number
  • What the gap will cost you, from a dated 2026 rate table for your market
  • Clarification letters drafted in one click
Enterprise

CUSTOM AI BUILDS

$4,900+build fee, plus a plan

For teams who need the system wired into what they already run — Procore, Bluebeam, Sage.

ReplacesThe re-keying between the estimate, the accounting system and the PM platform.

  • Trained on your own documents, templates and rate sheet
  • Integrated with Procore, Bluebeam, Sage or your ERP
  • Workflows only your company runs — not on any shelf
  • Single sign-on, your own retention rules and a signed DPA

The whole fleet

ALL EIGHT, WIRED
TO EACH OTHER.

Opened one at a time, the eight live programs still leave someone retyping numbers between them. Opened together, the takeoff lands in the estimator without a single re-keyed quantity, the awarded scope lands in ScopeGuard, the awarded subcontract lands in FloatGuard and TradeVet, and every figure on the bid traces back to the sheet it was measured from.

  • Quantities flow from the takeoff straight into the estimate — no export, no CSV, no typo
  • One project database across all eight, so a drawing revision updates every downstream number
  • A setup call on a real job of yours, so the first bid you run through it is a live one
  • The same login on the MaraponeAI mobile app when it lands, Q4 2026, at no extra cost

Thousands of hours of purpose-built engineering — 660-odd scope requirements, 57 priced assemblies, 27 risk rules and eight finished programs, tested on live tenders. You are not funding that work. It is done, it is running, and a plan is the key to it. You are signed in and uploading inside five minutes.

A 30-second pass across all five programs, cut together — not one unedited take. See it run on your own documents →

05 — How it’s built

YOUR DRAWINGS
GO NOWHERE ELSE.

To read your tender package we have to receive it — so here is exactly what happens to it. It lands in a workspace scoped to your account, is read by Marapone’s own model on Marapone’s own hardware, and is never pooled, never sold on to an AI vendor, and never used to train anything. No OpenAI, no Anthropic, no Google in the path. You can delete a project, files and all, from inside the program.

YOUR WORKSPACE Drawings, specs, quotes uploaded over TLS Marapone's own model our hardware · your tenant encrypted at rest Takeoffs, bids, letters yours to export or delete AI VENDORS no third party no training no other tenant

Whose model reads it

OURS. ONLY OURS.

Every page of your tender package is read by a model Marapone built and fine-tuned on open weights, running on hardware Marapone controls. Nothing is forwarded to a commercial AI API, so there is no second company in the chain with a copy of your bid and its own terms of service.

Strict-NDA work

ONE SUB-PROCESSOR

Because the reading happens in-house, your disclosure list is short and specific rather than a page of AI vendors. We will sign a DPA, name our infrastructure providers, and set your own retention window. Send this to IT →

If you leave

YOU TAKE THE WORK

Cancel and the programs close — but every takeoff, estimate, levelled bid and report you produced exports in formats that open in Excel, Bluebeam and a PDF reader. We do not hold your output hostage to keep a subscription alive, and we will delete the lot on request.

Before you ask IT

IT RUNS IN THE BROWSER
YOU ALREADY HAVE OPEN.

No GPU, no Docker, no server, no installer, no admin rights. The five-year-old Dells your estimating team already uses are the target, not an exception to it — the heavy reading happens on our hardware, and what arrives at the laptop is a web page. If your staff can open a browser tab, they can open this.

No database to stand up, no licence key, no rollout. Leaving is cancelling from your own dashboard.

And you are not doing it alone

WE GET ON A CALL
AND RUN A JOB WITH YOU.

Every plan includes a live screenshare with the people who built it. We sit with you, take a real tender of yours from the drawing set to a priced bid, and answer the questions that only come up on your own documents.

  • 60 minutes on Pro and Firm
  • 30 minutes on Field

Booked at your convenience, not on a clock that starts at payment. If it cannot do useful work on your documents by the end of the call, cancel from your dashboard and it stops there — and if you are still in the seven free days, you will not have paid us anything at all.

06 — Who builds this

BUILT BY CONSTRUCTION PROS,
NOT CONSULTANTS.

Ten-plus years in field construction operations before a line of this was written — pouring, coordinating trades, chasing RFIs that should have been answered three weeks earlier. We didn’t research these problems. We were the ones eating them.

08 — The difference

PRICED FOR
A CONTRACTOR.

The big construction platforms price against your annual volume, bill you per module, and add an implementation fee before anything is switched on. Grow, and the invoice grows with you for work you were already doing.

We charge one flat price per firm, whatever you build. Sign in and it works today — there is nothing to roll out, because there is nothing to install.

Marapone Big platforms
What sets the price Seats Your annual volume
Implementation fee $0 $5,000+

Minimum commitment One month One year

Platform figures are typical published ranges for mid-size GC packages, not quotes. Yours will differ — ask them, then compare.
