But how can one love someone whom one does not know?
CatéGPT: artificial intelligence in service of discovering the texts of the Church
Introduction
CatéGPT was born from the desire to make the foundational texts of the Catholic Church accessible to as many people as possible. The goal is not to replace the Church or priests, but to help users discover the answers already present in Sacred Scripture, the Catechism, the Councils and the documents of the Magisterium. CatéGPT is part of an effort of transmission, formation and discovery.
Why CatéGPT?
The name CatéGPT brings together the Catechism of the Catholic Church and modern artificial intelligence technologies. The goal is to put these technologies at the service of spreading the intellectual and spiritual heritage of the Church.
Our philosophy
Artificial intelligence is not meant to replace the reading of the texts. On the contrary, it should help discover them. CatéGPT always encourages direct consultation of the original sources.
Our identity
The CatéGPT logo shows a hand holding the keys of St Peter. The gold key symbolises the Church, the silver key technology, and the digital network extending the hand evokes artificial intelligence. Together they express the meeting of Catholic tradition and contemporary tools.
Sources
Every answer points back to the official texts of the Church. These are the sources CatéGPT relies on and makes available to you, in your language wherever an edition exists.
Official documents of the Holy See
Published on vatican.va. Links open the edition matching your language where one exists.

Bibles
A scripture reference given at the end of an answer opens the cited passage in the reading language. For French, English and Spanish it lands on the verse; elsewhere on the chapter. When an edition does not carry the book or chapter asked for, the link moves to the Clementine Vulgate, then to The Bible in Its Traditions — never a dead link.

Novus Ordo and Vetus Ordo: two forms of the Roman rite
CatéGPT’s liturgical pages show both calendars of the Roman rite. On some days they celebrate the same feast; on other days they celebrate different ones — a switch then lets you move from one to the other.
- NOM — Novus Ordo Missae
- The form of the mass promulgated after the Second Vatican Council (1969 missal), celebrated in the vernacular in most parishes. Its texts come from AELF.
- VOM — Vetus Ordo Missae
- The earlier form of the Roman rite, celebrated in Latin according to the 1960 rubrics (the missal of Saint John XXIII). Its calendar has its own feasts and its own ranking of degrees (1st to 4th class). Its texts come from the Divinum Officium project.
CatéGPT treats both forms equally: you choose which one is shown first in your preferences, and you can switch at any time on the liturgical pages.
Disclaimer
CatéGPT is a documentary assistance tool. It does not replace the authority of the Magisterium, a priest, a spiritual director, or the sacrament of confession.
