Terms of use

Last updated October 1, 2026

These terms apply to truepart.ai, the demo, the contact forms, the invite-only pilot, and the agent interfaces described in section 5 (together, the “Service”). By using the Service you agree to them. If you do not agree, do not use the Service. A written agreement signed with TruePart (such as a pilot agreement) takes precedence over these terms where the two differ.

1. A technical preview

TruePart is a technical preview. It is not commercially validated and not certified for any engineering, regulatory, or safety purpose. Features, scope, and availability may change or stop at any time, with or without notice.

2. Not engineering advice; you verify every part

Everything the Service produces, including readings of a drawing, questions, specifications, CAD models, STEP and STL files, and verification results (“Output”), is provided for your review. Output is not engineering advice, an approved design, or a statement that a part is fit for any use. Verification covers only the checks it lists, at nominal dimensions; it does not check tolerances, materials, manufacturability, strength, or safety.

You are solely responsible for having a qualified person independently check all Output against the original drawing and your requirements before you quote, manufacture, sell, or use any part. Do not use the Service or its Output for safety-critical, medical, aerospace, automotive safety, nuclear, or other applications where an error could cause injury, death, or significant damage.

3. Your content

You keep your rights in the drawings and information you provide. You grant TruePart the permission needed to store and process them only to provide the Service to you, and for any additional use you explicitly allow.
You confirm that you have the right to provide each drawing and that doing so does not breach any confidentiality obligation, law, or third-party right.
Customer engineering data (your drawings, CAD models, STEP and STL files, the requirements extracted from your drawings, your answers to clarification questions, and the other engineering files TruePart generates for you) is not used to train shared models unless you explicitly choose otherwise. This is the default on every plan and no plan changes it. Allowing training is a separate, voluntary choice; it is never a condition of a price, access, a discount, or any feature, and withdrawing it applies from then on. See Privacy.
Do not upload drawings or technical data that are export-controlled (for example under ITAR or the EAR), classified, or subject to a government security requirement.

4. Acceptable use

You agree not to:

break the law, or infringe or misappropriate anyone’s rights, through the Service;
access accounts or data that are not yours, probe or test the Service’s security outside our security policy, or disrupt or overload it;
copy, scrape, reverse engineer, or resell the Service, or use it to build a competing product, except where the law does not allow this restriction;
send spam, malware, or unlawful content through the Service or its forms.

We may suspend or end access to anyone who breaches these terms.

5. Agents and automated access

TruePart documents a few ways for software agents to read its public information: an MCP server, an A2A agent, a public read-only API, and tools on the public pages (the “agent interfaces”). They answer what TruePart is, which of its pages are public, and how a person requests access. You, or an agent acting for you, may use them automatically to read the public information they serve, within their rate limits. An agent may also register with TruePart and receive tokens that raise its rate limit on the MCP server and the A2A agent; the ways to register and to get, renew, or revoke those tokens are part of the agent interfaces. This is an exception to section 4 for the agent interfaces only: everywhere else, its bans on scraping, probing, and overloading the Service still apply.

Do not work around a rate limit, for example by spreading requests over many addresses or many registrations.
Registering is optional: every agent interface works without it. A registration and its tokens give a higher rate limit and nothing else. They give no access to any account or its data.
Keep an agent’s credentials (its tokens and the secret it uses to ask for a link to an account) secret, and do not share them with another agent or person. TruePart may revoke a registration and its tokens, or refuse to issue them, at any time.
If you link an agent to your TruePart account, you are responsible for that agent’s use of the Service under these terms.
An agent must not send a request for access on a person’s behalf. It may tell the person how to request access; the person sends the request themselves.
The agent interfaces serve public information only, and they may change, be limited, or stop at any time.

6. Intellectual property

The Service, its software, designs, text, and the TruePart name and logo belong to TruePart or its licensors, and no rights are granted except as these terms state. Certain TruePart technologies relating to evidence-gated engineering workflows, deterministic CAD generation, requirement-level verification, provenance, and controlled revision are patent pending.If you send us feedback or suggestions, we may use them without obligation to you.

7. Disclaimer of warranties

THE SERVICE AND ALL OUTPUT ARE PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTY OF ANY KIND. TO THE FULLEST EXTENT PERMITTED BY LAW, TRUEPART DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AND UNINTERRUPTED OR ERROR-FREE OPERATION.

8. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, TRUEPART AND ITS OFFICERS, EMPLOYEES, CONTRACTORS, AND SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, OR GOODWILL, OR FOR THE COST OF SCRAPPED OR REWORKED PARTS, MATERIALS, MACHINE TIME, DELAYS, OR SUBSTITUTE SERVICES, ARISING FROM OR RELATED TO THE SERVICE OR ANY OUTPUT, EVEN IF ADVISED OF THEIR POSSIBILITY. TRUEPART’S TOTAL LIABILITY FOR ALL CLAIMS RELATED TO THE SERVICE IS LIMITED TO THE GREATER OF THE AMOUNT YOU PAID TRUEPART FOR THE SERVICE IN THE 12 MONTHS BEFORE THE CLAIM AND ONE HUNDRED U.S. DOLLARS (US$100).

Some jurisdictions do not allow some of these exclusions or limits; where that is the case, they apply to the fullest extent the law allows.

9. Indemnity

You will defend, indemnify, and hold harmless TruePart and its officers, employees, and contractors from any claim, loss, or expense (including reasonable legal fees) arising from your content, your use of the Service or of any Output, including parts made from it, or your breach of these terms.

10. Third parties

3D Services USA is a separate company, not TruePart. Any service it provides is between you and it, under its own terms; TruePart is not responsible for it. The Service runs on third-party hosting, delivery, and email infrastructure that TruePart does not control.

11. Forward-looking statements; no offer of securities

Statements on the Service about plans, milestones, markets, and future features are forward-looking. They reflect current intentions, are not promises, and may change; actual results may differ materially. Nothing on the Service, including the investors page, is an offer to sell, or a solicitation of an offer to buy, any security, or investment, legal, or tax advice. Any offering will be made only through definitive documents and only where permitted by law.

12. Changes and termination

We may update these terms; the date above shows the latest version, and using the Service after an update means you accept it. You may stop using the Service at any time. Sections 2, 3, and 6 through 13 survive any end of your use.

13. General

If any part of these terms is found unenforceable, the rest remains in effect, and that part is enforced to the fullest extent permitted. Our not enforcing a term is not a waiver. You may not assign these terms without our consent.
