These Terms of Service (“Terms”) govern your access to and use of Wundermator (“the Service”), operated by Wundermator Pty Ltd (ABN 54 697 928 975 · ACN 697 928 975) (“Wundermator”, “we”, “us”). By creating an account or using the Service, you agree to these Terms.

1. The Service

Wundermator is an AI-powered tool that generates draft construction cost documents from architectural plans you upload. Each output is produced by passing your uploaded files through a large language model, applying our calculation logic, and returning a structured spreadsheet. Depending on your account type, the Service produces:

Builder estimates — draft cost estimates formatted for import into project-management software;
Build Feasibility Reports (architects, designers, clients & homeowners) — a preliminary, design-stage feasibility document expressing an indicative cost range;
Trade Cost Proposals (sub-trade contractors) — a draft, trade-scoped schedule of quantities and indicative costs for a single trade, with editable unit rates;
Product take-offs (suppliers & distributors) — draft quantity schedules of specified products measured from drawings.

2. Outputs are preliminary feasibility tools — not quotes or professional advice

Every output of the Service is a draft document generated by automated systems, provided to assist with early-stage budgeting and feasibility only. No output is a builder’s quote or tender, a structural engineer’s calculation, a quantity surveyor’s report, architectural advice, financial advice, or any other form of professional advice, and no output creates any contractual price commitment by anyone. AI models can and do make mistakes — including in pricing, quantities, item identification, and interpretation of plans and building codes. Actual construction costs vary with market conditions, site conditions, specification decisions, and contractor pricing, and will differ from any estimate or range produced by the Service.

You are responsible for verifying every output of the Service before relying on it for any commercial, contractual, structural, or regulatory purpose. We strongly recommend independent verification — for example by a qualified builder, estimator, or quantity surveyor — before any output informs a binding decision.

3. Professional users and your clients

If you use the Service in the course of a profession or trade (including as an architect, building designer, builder, estimator, sub-trade contractor, supplier, or distributor):

You remain solely responsible for any advice, document, quotation, or representation you provide to your own clients, including any use you make of Service outputs. The Service does not discharge, and is not a substitute for, your professional obligations, judgement, or duty of care.
You must present outputs to your clients as what they are: a preliminary feasibility guide with an indicative range — never as a fixed price, quotation, tender, or guaranteed cost, and never as a substitute for professional cost advice where your client requires it.
Any cost range shown (for example ±10%) is indicative only and is not a representation that final costs will fall within that range.
Suppliers and distributors must independently verify quantities in any take-off before ordering, quoting, or supplying product. We are not liable for over- or under-ordering based on a take-off.
Contractors must independently verify the quantities and rates in any Trade Cost Proposal against the drawings, site conditions, and their own supplier pricing before quoting, tendering, ordering, or committing to any works. Unit rates in a Trade Cost Proposal are indicative regional defaults provided as a starting point for your own pricing. A proposal covers a single trade’s scope only, and scope allocation between trades may differ from your actual contract. We are not liable for under- or over-quoting, tender losses, or scope gaps based on a Trade Cost Proposal.
Each output is prepared solely for you, the account holder. We do not assume any responsibility or duty of care to any other person, no other person may rely on an output, and your clients and other third parties acquire no rights under these Terms.

Indemnity: you indemnify Wundermator against loss we suffer from a claim by a third party (including your client) to the extent the claim is caused by (a) your breach of these Terms, or (b) your representing a Service output to another person as a quote, tender, guaranteed cost, or professional cost advice. This indemnity is reduced proportionately to the extent that our negligence, or our breach of these Terms, caused or contributed to the loss, and it does not limit any rights you have under the Australian Consumer Law.

4. Third-party software formats

The Service can format outputs for import into third-party software (such as WunderBuild, BuildXact, or Buildertrend). Those products are owned by their respective companies; we are not affiliated with, endorsed by, or responsible for them. Import behaviour, subsequent calculations, and any transformation applied by third-party software are outside our control — verify your data after import.

5. Your account

You must provide accurate information when creating an account. You are responsible for keeping your password secure and for all activity that occurs under your account. You must be at least 18 years old.

6. Acceptable use

You agree not to:

Upload files you don’t have the right to use (copyright infringement, confidential third-party plans, etc.)
Attempt to extract, reverse-engineer, or scrape the Service’s underlying logic, prompts, or models
Resell, sublicense, or redistribute outputs without our written consent
Use the Service to evaluate or build a competing product
Submit malicious files (malware, oversized files designed to crash the system, etc.)

7. Pricing and payment

The Service is sold on a pay-per-use basis at the prices displayed at the time of purchase for your account type (for example, builder estimates, Build Feasibility Reports, and product take-offs are priced separately). All prices are in Australian Dollars and are exclusive of GST unless stated otherwise. Payment is processed via Stripe.

Estimates that fail due to system errors are automatically refunded as account credit. See our Refund Policy for details.

8. Intellectual property

You retain all rights to the plans, files, and information you upload. By using the Service, you grant us a limited, non-exclusive licence to process your files for the sole purpose of generating your estimate. We do not use your uploaded plans to train AI models.

The Wundermator name, software, calculation methodology, and brand are owned by Wundermator Pty Ltd. You receive no licence to these except the right to use the Service as provided.

9. Limitation of liability

To the maximum extent permitted by law:

We provide the Service on an “as-is” basis with no warranties beyond those mandated by law.
Our total liability for any claim arising from your use of the Service is limited to the amount you have paid for the specific output giving rise to the claim.
We are not liable for indirect, consequential, or special damages — including lost profits, lost contracts, cost overruns, tender or project losses, lost time, or business interruption — including where they arise from a decision made in reliance on a Service output.

Nothing in these Terms excludes consumer guarantees that cannot be excluded under the Australian Consumer Law. Where such a guarantee applies and the law permits, our liability for its breach is limited, at our option, to resupplying the relevant output or refunding the amount paid for it.

10. Termination

We may suspend or terminate your account if you breach these Terms or engage in fraudulent or harmful activity. You may close your account at any time by emailing us — see our Privacy Policy for data deletion rights.

11. Changes

We may update these Terms from time to time. Material changes will be communicated via email or a notice on the Service. Continued use after changes constitutes acceptance.

12. Governing law

These Terms are governed by the laws of Tasmania, Australia. Any disputes will be subject to the exclusive jurisdiction of the courts of Tasmania.
