Line-by-line bill of quantities, market price comparison, and a risk audit of the fixed-price contract you're about to sign. Built for Australian homeowners. Reviewed and signed by a human.
Our pipeline extracts your drawings with AI vision, builds an independent bill of quantities, compares each line against current Melbourne market rates, and flags every clause that's likely to cost you. Then a human reviews and signs the report before it goes out.
Drag in two PDFs and answer ten short questions about your build. Pay $249 by Stripe. Five minutes total.
Computer vision reads every page — floor plans, elevations, specs, schedules — and builds a structured model. ~90 line items, cross-referenced to your drawings.
A trained reviewer checks the AI output, runs the comparison against your tender, and writes the red flags and negotiation talking points. They sign the report personally.
BOQ, line-by-line tender comparison, ranked red flags with dollar impacts, copy-paste negotiation language for your builder. Sign with confidence or push back with evidence.
One-page scorecard at the top: total, our independent estimate, delta, verdict (fair / above / significantly above) and the top three actions before signing.
~90 items across substructure, frame, roof, envelope, finishes, services. Each with quantity, unit, market low/mid/high, our total, and a confidence rating. Cross-referenced to your drawings.
Trade-by-trade. Where is the margin above norm? Which trades are under-allowed? What looks fair? Each delta shown in dollars and percent.
Critical, warning, info — each with an estimated dollar impact. Missing geotech? Uncapped rise-and-fall? Council infrastructure charges absent? Each one written for you to understand and your builder to respond to.
Eight talking points ranked by likely return. "Please cap rise-and-fall at 5% in line with VIC's 2025 protections legislation." Sentences you can email your builder verbatim.
Every report has a real human's initials on the cover. We will never automate the sign-off. PI insured. Drafted under terms reviewed by an Australian building solicitor.
You may have heard about building brokers. They're free to homeowners. They help you compare designs and pick a builder. They're paid by the builder — typically 2–4% of the contract you sign. That means the broker has no incentive to flag that the contract is too expensive, the inclusions are thin, or the rise-and-fall clause is uncapped. Their pay-day depends on you signing.
We do the opposite. You pay us $249, once, before you sign. We have one job: tell you what's in the tender and what isn't.

"Our most recent calibration ran against the full cost ledger of an Indigenous health-service housing development in regional Queensland — 27 trade contracts, 80+ invoices. The mid-estimate landed within 12% at project halfway, then within 3% after rate refinement. This is what reviewed AI looks like."
Independent audit of one fixed-price Australian residential building tender. Melbourne metro postcodes (3000–3199).
Outside Melbourne metro? Doing a custom build? Owner-builder permit? Get in touch — we handle those case-by-case at the same price.
No. We're not a licensed quantity surveying practice. We're an independent information service that uses AI document extraction backed by human review. The output uses the same methodology as a QS-style report, but we don't sign certificates of construction cost and we don't accept liability the way a QS firm does.
If you need a stamped QS report for a court, bank, or depreciation schedule, you need a QS firm. If you want to sanity-check the contract you're about to sign for $249 in 24 hours, you want us.
Our most recent benchmark run produced a mid-estimate within 3% of actual cost on a real Melbourne single-storey project. Each line carries a confidence rating (high / medium / low) so you know which numbers we're sure about and which are estimates. We refresh rates against current Bunnings and Reece pricing weekly, and we re-calibrate against new real-project data as it comes in.
Every report is reviewed and signed by a trained human reviewer before it goes out. We list the reviewer's initials on the report cover. In the first phase, that's the founder personally. As volume grows we'll bring in QS-trained reviewers part-time. We will never automate the sign-off step.
That's a good outcome. Most tier-1 builder tenders we benchmark come in within 3–8% of independent market pricing — that's "fair, upper-band". When that happens, the report tells you so, and then redirects you to the risks: which clauses are uncapped, which inclusions are missing, what to confirm before signing.
The price being fair doesn't mean the contract is. That's most of what we find.
Probably not, if you handle it well. The negotiation language we provide is fact-based and respectful. We never frame the builder as the bad guy. Our report says things like "please cap rise-and-fall at 5% in line with the 2025 protections legislation" — not "your builder is ripping you off." Most builders respond reasonably to a customer who has done their homework. Some don't, and that's a useful signal too.
We store your uploads encrypted for 30 days for QA and dispute purposes, then delete. We may anonymise the structure of your tender (no names, no addresses) to improve our calibration over time. You can request deletion at any time.
Our calibration is most accurate where we have the most data. Melbourne metro postcodes (3000–3199) is our launch zone. We're expanding to Sydney and Brisbane next. Outside those, we'll still produce a report for the same price, but the confidence rating drops, and we'll flag that on the cover page.
We carry professional indemnity insurance and our T&Cs are drafted by an Australian building solicitor. We explicitly limit our liability to refund of the report fee. We are not a substitute for legal review of your contract — we recommend pairing our report with a $400–$900 contract review from a building solicitor.
