Groundbook AI Terms of Service

Last updated: 2026-08-22

1. Agreement

These Terms of Service (the "Terms") are an agreement between Matter0, Inc., a Delaware corporation ("Matter0," "we," or "us"), makers of the Groundbook AI software platform, and the customer accepting them ("Customer," "you"). By creating an account or using the Service, you accept these Terms on behalf of your organization and confirm you have authority to do so.

2. The Service

These Terms govern Groundbook AI, our software platform that uses artificial intelligence to review construction documents (drawings, specifications, and related files) for conflicts, inconsistencies, and compliance issues, and presents findings with source evidence, together with the website groundbook.ai and related tools (collectively, the "Service").

The Service is an analysis tool, not professional engineering or architectural advice. Findings are informational. The design professional of record retains full professional responsibility for the design and for any decision made using the Service's output. We do not stamp, seal, approve, or certify designs, and no output constitutes a permit decision or code approval.

3. Accounts

You are responsible for your account credentials and for all activity under your account. Accounts are for a single organization; you may not share access outside it.

4. Fees and payment

The Service is pay-as-you-go: fees are based on usage (for example, per review, per sheet, or per project), at the rates stated on the pricing page or an order form at the time of purchase.

Payment is due before use. You either pay for usage at the time of purchase or buy prepaid credits, which are drawn down as you use the Service. There is no recurring subscription fee.
Prepaid credits are non-transferable and non-refundable except as required by law, and do not expire.
Fees are exclusive of taxes; you are responsible for applicable taxes other than our income taxes.
Fees for completed reviews are non-refundable except where these Terms provide otherwise.
We may change prices at any time; changes apply only to future purchases, never to usage already paid for or credits already purchased.

5. Customer Project Data and ownership

"Customer Project Data" means the drawings, specifications, calculations, and other project materials you submit to the Service, together with project-specific data created through the Service. This includes page images, extracted facts and graph data, AI-generated issues and reports, audit trails, corrections, issue accept/reject decisions, and comments.

You retain all rights you have in materials you submit, and, as between you and us, you own project-specific outputs created for you. We claim no ownership of Customer Project Data.
You grant us a non-exclusive, worldwide, royalty-free license to host, process, and display Customer Project Data solely to (a) provide and secure the Service, (b) provide support, and (c) improve Service quality as described in Section 6. All rights not granted are reserved by you.
You are responsible for having the rights to submit project materials, including documents belonging to your clients.

"Derived Learning Data" means labels, failure types, evaluation results, performance metrics, and other learning signals that have been aggregated or de-identified so they do not identify you or your projects and do not reproduce Customer Project Data. Raw corrections, comments, excerpts, and other project-specific records remain Customer Project Data until they meet this standard.

We own Derived Learning Data and abstracted technical or jurisdictional knowledge that does not identify you or your projects and does not reproduce Customer Project Data.

6. How we use your data

This section is the core of these Terms. The commitments in Section 6.1 always apply.

6.1 Commitments that always apply

We never sell Customer Project Data or Derived Learning Data, and never disclose either to third parties except the subprocessors in Section 6.2 or where law requires.
No other customer of the Service can see your Customer Project Data, your projects, or anything identifiable as yours.
All data use under this section exists only to provide the Service to you and to improve the quality of the Service. It is never used to expose your data to anyone else.

6.2 Subprocessors

We use third-party subprocessors to operate the Service, including cloud hosting and storage (Amazon Web Services), payment processing (Stripe), analytics, and AI model providers. Customer data is securely hosted in the United States using Amazon Web Services. We apply the safeguards described in these Terms regardless of where you are located. Every AI model provider we use processes Customer Project Data under commercial API terms that prohibit it from training its models on that data. A current subprocessor list is available on request, under confidentiality obligations.

6.3 Support, debugging, and issue investigation (always on)

Our personnel may access and review your Customer Project Data and Derived Learning Data when needed to provide the Service to you: to respond to your support requests, investigate and fix errors or processing failures, and verify the quality of findings on your projects. This access is limited to personnel who need it for those purposes and is covered by the confidentiality obligations in Section 9.

6.4 Internal evaluation and harness improvement (always on)

We use Customer Project Data and Derived Learning Data internally to evaluate and benchmark accuracy and to improve the prompts, tools, routing, workflows, and other parts of our AI harness. This includes creating modified internal test copies of documents, for example with intentionally introduced errors, to measure detection quality. Test copies are held to the same confidentiality as the originals. Results are disclosed only in aggregate, never in a form identifying you or your projects. This use is necessary to provide and maintain a reliable Service and cannot be opted out of.

6.5 Internal model training (on by default; opt out anytime)

We use Customer Project Data, including necessary drawing excerpts, corrections, issue decisions, and comments, together with Derived Learning Data, to train models developed and used internally by Groundbook to provide and improve the Service. This is Groundbook's internal model-training process, not training performed by third-party AI vendors. We do not send or share this Groundbook training data with third-party AI vendors for their model training. We never share or show this training data to other customers. Before training, we remove or mask personally identifiable information contained in title blocks and make reasonable efforts to remove or mask other information that identifies you, your company, or your project. Training data remains confidential.

You may opt out of this Section 6.5 at any time by emailing support@groundbook.ai. After your opt-out takes effect, we will not use your data in future model-training runs. Opting out does not require us to retrain existing models or reverse completed improvements. Because customer feedback helps our models improve, opting out may cause your experience and the precision and recall of findings to improve more slowly.

6.6 Retention and deletion

To request permanent deletion of Customer Project Data, email support@groundbook.ai. We will confirm when permanent deletion is complete, except where law requires retention.
De-identified labels, aggregate metrics, evaluation results, abstracted technical or jurisdictional knowledge, and improvements already incorporated into models or the AI harness survive permanent deletion because they no longer identify you or your projects.

6.7 Personal information

Our Privacy Policy explains what personal information we collect, how we use and share it, where it is processed, how to exercise available privacy rights, and how to contact us.

7. Acceptable use

You may not use the Service to violate law or third-party rights; submit content you lack rights to; attempt to extract our models or reverse engineer the Service; resell the Service without a written agreement; or use output to represent that a design has been approved by any authority.

8. Our IP and feedback

We own the Service, its software, models, and all improvements. If you send general suggestions or feedback about the Service, we may use them without obligation. Project-specific corrections, comments, and other feedback remain Customer Project Data and are handled under Sections 5 and 6. Nothing in this section transfers any Customer Project Data to us.

9. Confidentiality

Each party will protect the other's non-public information with at least reasonable care and use it only to perform under these Terms. Customer Project Data is our confidentiality obligation regardless of marking.

10. Warranties and disclaimers

We warrant that we will provide the Service with reasonable skill and care. Otherwise, the Service is provided "as is." We do not warrant that the Service will find every issue in a document set or that findings are free of error. AI-generated findings can be wrong or incomplete; you must independently verify findings before relying on them.

11. Limitation of liability

Except for breaches of Section 6 or 9, or a party's willful misconduct: (a) neither party is liable for indirect, incidental, consequential, or punitive damages, or lost profits; and (b) each party's total liability under these Terms is capped at the fees you paid to us in the 12 months before the event giving rise to the claim.

12. Indemnification

We will defend you against any third-party claim alleging that the Service, as provided by us and used as permitted by these Terms, infringes that party's intellectual property rights, and we will pay damages finally awarded on that claim or settlements we approve. This does not apply to claims arising from Customer Project Data or from combining the Service with anything we did not provide.

You will defend us against any third-party claim arising from Customer Project Data or from your use of the Service in violation of these Terms or applicable law, and you will pay damages finally awarded on that claim or settlements you approve.

The party seeking defense must promptly notify the other, let the other control the defense, and reasonably cooperate.

13. Term and termination

These Terms apply while you use the Service. Either party may terminate at any time; you remain responsible for accrued fees. Sections 5–6.6, as to committed uses, 8–12, and 14–15 survive termination. You may request permanent deletion under Section 6.6.

14. Changes to these Terms

We may update these Terms with 30 days' notice for material changes by email or in-product notice. Continued use after the effective date is acceptance. We will not reduce the protections in Section 6.1 for existing Customer Project Data without your consent.

15. Governing law and disputes

These Terms are governed by the laws of the State of Delaware, excluding conflict-of-law rules. Disputes will be resolved in the state or federal courts located in Delaware, and each party consents to that venue.

16. Miscellaneous

Neither party may assign these Terms except to a successor in a merger or asset sale. If a provision is unenforceable, the rest remains in effect. These Terms plus any order form are the entire agreement. Notices to us: support@groundbook.ai.
