Terms of service
These terms apply to the use of CAFA AIG² (the service). By signing in you accept them.
1. The service
CAFA AIG² is a web application, operated by CAFA Lab, Inc., that generates and verifies multiple-choice items from an Item Model and an Ontology Model you write. It runs in your browser; when you sign in, it can also store model versions in your workspace, issue server-side certificates for generated sets, and draft models from source material with an AI model.
The service is offered as a pilot. Features, plans and allowances may change; we will state changes on this page with a new revision number.
2. Accounts
Accounts are created by invitation. You sign in with a one-time link sent to your email address; there is no password. You are responsible for keeping access to that mailbox secure, and for what is done in the service under your account.
Your account belongs to one or more organizations (for example, a course cohort or an institution). The organization's plan sets what you may do — in particular how many AI drafts you may request per day or in total. An organizer may add or remove members.
3. Your content
Models, items, sets and files you create remain yours. You grant CAFA Lab only the rights needed to store, process, display and export them for you, and to keep the audit record described in the Privacy notice.
You are responsible for the content you enter and for its use. Do not enter material you have no right to use, personal data about identifiable people, or content that is unlawful.
Saved model versions are immutable by design: a saved version is never edited in place, and certificates issued for it are never edited. Deleting an account removes your identifying data (see Privacy) but may leave version and certificate records that are the audit trail of sets already issued.
4. AI drafting
When you use Draft, the source material you provide and the conversation with the drafting assistant are sent to a third-party AI model provider (currently Anthropic) through CAFA Lab's account. CAFA Lab does not store that material on its servers; the provider's own terms and data policies apply to the call. Drafts are proposals: the app measures them, and you decide what to keep.
Drafting is metered per user according to your organization's plan. Requests beyond the allowance are refused with a message saying so. Attempts to circumvent allowances or access controls are a breach of these terms.
5. What is verified and what is not
The service verifies, over every generated item, structural properties only: that no placeholder is left unresolved, that no two items share the same conditions, and that each item's answer position is valid. A server certificate records these checks and the hashes of the model version and the set. The service does not verify — and does not claim — the domain accuracy of values and options, curriculum fit, difficulty, or the equivalence of items that differ only in surface-only variables. Every certificate states this. See the Disclaimer.
6. Acceptable use
- Use the service only for creating and reviewing assessment content.
- Do not attempt to access another organization's workspace, to write certificates or audit records directly, or to probe the service's security.
- Do not automate requests against the service beyond ordinary use of the app.
- Do not misrepresent a certificate: it certifies what section 5 says, for the exact set hash it names.
7. Availability, changes, termination
The service is provided as is, on a best-effort basis, without a guaranteed service level. We may suspend or end an account that breaches these terms, and may discontinue the service with reasonable notice. You may export your content at any time from the app.
8. Liability and law
To the extent permitted by law, CAFA Lab is not liable for indirect or consequential loss arising from use of the service, including any use of generated items in an examination. These terms are governed by the laws of the State of Maryland, USA.
