Mass in Every Language is a project to make the Order of the Mass accessible across many languages in one place, with clear notes about which translations have been reviewed and which were automatically generated.

The app was developed in Django with LLM-assisted translation workflows to help scale multilingual content creation. After iterating in the dynamic Django app, the site was published as static pages using django-freeze for fast, simple deployment.

Current scope (as of this write-up):

• 99 languages currently listed
• 4,851 unique side-by-side language pairings (n choose 2)

PDFs are also available for every individual language and every side-by-side pairing.

There’s still quite a bit of review work to do, but I’ve already worked with native speakers and priests to review and confirm translations in quite a few of the languages.

From a product perspective, the goal is practical: help people follow the liturgy in their own language (or while traveling), while being transparent about translation quality and provenance.
