Terms of Service

“We” and “us” mean PreConstruct AI. “You” means the person or company with the account. If you are using this on behalf of a company, you are confirming you are allowed to accept these terms for it.

By creating an account you agree to these terms and to the Acceptable Use Policy. Our handling of your data is covered by the Privacy Policy.

PreConstruct AI reads construction drawings and helps you turn them into takeoffs, estimates and proposals. It shows where each number came from — which sheet, which region of the page — so you can check it.

It is an assistant, not an estimator. Results are a starting point for a professional to verify, not a finished quantity survey. The product is deliberately built to flag what it cannot read reliably rather than fill the gap with a guess, but it can still be wrong.

You are solely responsible for checking every quantity, classification and price before using it in a bid, a contract, or a proposal to a client.

This is the central term of this agreement. A tool that reads drawings in minutes is only safe if a person who knows the trade checks the output. If you put an unverified number into a bid, that is your decision and its consequences are yours.

To the fullest extent the law allows, we are not liable for lost profit, underbid work, missed scope, project delays, or any indirect or consequential loss arising from your use of the service — including results that turn out to be wrong.

We are also not liable for failures of the third-party AI services the product depends on, which can be unavailable, slow, or mistaken.

Where liability cannot be excluded by law, it is limited to the amount you paid us in the twelve months before the claim.

Nothing here limits liability for anything that cannot lawfully be limited, including fraud or personal injury caused by negligence.

Proposals can display payment instructions you have written. That is the whole extent of it.

We do not process, hold, transmit, or guarantee any payment between you and the people you work for. We are not an escrow, not a payment processor for your work, and not a party to your contracts. If a client does not pay you, that is between you and them.

Keep your sign-in details secure and tell us promptly if you think someone else has access. You are responsible for what happens under your account, including what people you invite to your team do.

One person, one account. Sharing a single login between people defeats the review trail that makes the estimates defensible.

Your drawings, takeoffs, estimates and proposals belong to you. We claim no ownership of them.

You give us permission to store and process them for the sole purpose of providing the service to you. We do not use your documents to train AI models.

You confirm you have the right to upload what you upload. If a drawing belongs to a client or an architect, make sure your arrangement with them allows you to process it this way.

Subscriptions are billed monthly or annually in advance through Stripe. Annual plans are charged at ten months’ price.

Each plan includes a monthly allowance of credits. Analysis costs credits based on how many sheets a drawing set contains, and the cost is always shown before you confirm. Credits roll over for one month and are not refundable or exchangeable for money.

Your first project is free, up to 50 sheets.

Founding members. The first 50 paying customers keep the price they signed up at for as long as their subscription stays active. If you cancel and return later, current pricing applies.

We may change prices with at least 30 days’ notice by email. A price change never applies to a founding member while their subscription remains active.

Cancel any time from Settings. Your subscription runs until the end of the period you have paid for, and is not renewed after that. We do not refund part-months.

Closing your account starts a 30-day recovery window. During it everything can be restored. After it, all of your data is permanently deleted — see the Privacy Policy. Export anything you want to keep before that date; exporting does not stop the deletion.

We may suspend or close an account that breaches the Acceptable Use Policy, does not pay, or is being used in a way that endangers the service or other customers.

Except where the breach is serious enough to require acting immediately, we will tell you what the problem is and give you a chance to fix it first.

We aim to keep the service running and will give notice of planned maintenance where we can. We do not promise uninterrupted availability, and the service is provided as-is beyond the commitments made in these terms.

If we change these terms materially we will email you before the change takes effect and ask you to accept the new version. Continuing to use the service after that means you accept it. If you do not, you can cancel and we will refund the unused part of a prepaid annual plan.

These terms are governed by the laws of the Province of Ontario and the federal laws of Canada that apply there. Disputes go to the courts of Ontario.
