eitri
Terms of use
Version 2026-10-16. Plain English; if anything here is unclear, ask before you rely on it.
What this is
eitri is a beta service that helps you design parts: Claude, an AI model made by Anthropic, writes and edits a CAD model, the service builds and checks it, and you can edit and export the result.
Check before you make it
Models and reports can be wrong. The checks are measurements of the model, not a guarantee that a part is safe or fit for a purpose. Check every dimension and every result yourself before you manufacture or rely on anything. Do not use eitri for parts whose failure could hurt someone.
Limits
- The free beta allows 5 agent requests a day and a monthly token budget per account. Builds, edits and exports are rate-limited.
- If the service's monthly spending limit is reached, agent requests pause for everyone until the next month.
- We may change limits, pause the service, or close accounts that abuse it.
Acceptable use
Use eitri to design things. Do not use it for anything else, to attack the service, to get around its limits, or to design weapons or anything illegal. One account per person.
Your designs
You keep the rights to what you design. You give us the rights we need to run the service: to store, build, render and show your projects to you, and to anyone you share a link with. See the Privacy notice for how interactions may be used to improve the product.
No warranty
The service is provided as it is, without warranties of any kind, and to the extent the law allows we are not liable for any loss arising from its use.
