Terms of use

Last updated 13 November 2026. These terms apply to Aquinian Studio (studio.aquinian.com) and the Aquinian website (aquinian.com). Aquinian is built and operated by Federated Intel AI LLC (FIA Labs), seated in Washington, D.C. Federated Intel AI LLC is owned by Unison Pictures Pty Ltd. "We" and "us" mean Federated Intel AI LLC.

Not a teaching authority

Aquinian is an AI study instrument for theology and philosophy, after the manner of Aquinas. It is not St. Thomas Aquinas, and it has no ecclesiastical teaching authority. Its output is not a magisterial statement, spiritual direction, pastoral counsel, or professional advice of any kind, and it can be wrong. Check what matters to you against the sources yourself; Check sources and the lookups are there to help you do that.

Credits and payments

A new account starts with 150 credits, with no card. The Aquinian membership is $15 a month and includes 900 credits each month. Extra credit packs can be bought; bought packs do not expire. Included credits are used first and do not roll over.

Credits are taken for work that lands. A run that does not land is 0 credits. Where a feature's cost depends on the work, the desk shows the most it can cost before you start, and you are charged only for what is used. An empty balance stops the engine.

Payments are processed by Stripe. The membership renews monthly until cancelled. Cancel anytime; access continues until the end of the paid period. Bought packs are not a cash credit.

If you are an Australian consumer, nothing in these terms excludes the Australian Consumer Law. If you have not used paid credits, you may request a refund of the first membership month within 14 days of first payment. After paid credits have been used, remaining unused included credits are not refundable except where the law requires it.

Accounts and guest access

You need an account to use Aquinian Studio. There is no guest wallet and no signed-out use, except the AICU Award 2026 judging demo at /demo while judging is open. The demo is time-limited: 100 credits per demo visit, and demo work is deleted after 24 hours. We can close the demo at any time.

Sources

The Latin of the Summa Theologiae shown by a lookup comes from Corpus Thomisticum and is used with the permission of the Fundación Tomás de Aquino. That permission is not an endorsement: the Fundación does not endorse, sponsor, certify or review Aquinian or its output. Corpus Thomisticum text remains subject to the Fundación's own terms, and each lookup links back to the source.

A lookup shows where a citation was found. It does not confirm that an answer reads the source correctly; that judgement stays yours.

Your material

You keep what you write and upload. You warrant you have the right to submit it. We process it to run what you ask for. We do not sell your material or use it to advertise to third parties.

Acceptable use

Do not use Aquinian to commit an offence, to harass or defame anyone, to infringe anyone's rights, to attack or overload the service, or to present its output as the teaching of the Church, a signed scholarly work, or the words of a real person.

Limitation

To the extent permitted by law, we are not liable for decisions made on the output or for errors in it. Where liability cannot be excluded, it is limited to the amount you paid us for the month in which the claim arose.

Governing law

These terms are governed by the laws of New South Wales, Australia, without excluding mandatory consumer rights.
