Vatican To Use AI To Translate Masses Live Into 60 Languages

Come Spring 2026, the Vatican will begin using Artificial Intelligence (AI) to translate Holy Masses live at St. Peter’s Basilica into up to 60 languages.

The faithful will be able to follow the liturgy in their own language via their smartphones.

The AI tool named Lara was developed by Translated – a world leader in AI-based language solutions – in collaboration with Carnegie-AI LLC, a company specialising in simultaneous interpretation technologies.

The faithful attending Holy Mass at the Vatican need not download any applications as the service will operate directly in their mobile gadgets’ browser. They only need to scan the QR codes that will be placed at the entrances and designated points of the Church. The QR codes will connect users to a website where they can follow the liturgy with real-time translation, in both audio and text formats.

The initiative was spearheaded by the Fabric of St Peter in collaboration with the Dicastery for Communication and the technology company Translated, and was presented on February 16 by the archpriest of the Basilica, Cardinal Mauro Gambetti, along with a series of liturgical initiatives and cultural projects in which technology has played a crucial role.

“St Peter’s Basilica has welcomed the faithful of all nations and languages for centuries. By making a tool that helps many understand the words of the liturgy, we want to serve the mission that defines the heart of the Catholic Church, universal by its very vocation,” stressed Gambetti.
