Looking for one place to keep up with all your favorite Catholic voices? Christendom brings together a growing, curated roster of over 150 Catholic creators and channels — from Bishop Robert Barron and Catholic Answers to Matt Fradd, Lila Rose, and many more — so you can watch, follow, and discover without bouncing between platforms.^1
Built by Longbeard Creative, the same team behind Magisterium AI (which has reached millions of people across 190 countries and is trained on 32,000+ Church documents), Christendom describes itself as a "big tent" platform: unapologetically Catholic and evangelical, but welcoming diverse perspectives within the Church.^2 You can create an account, subscribe to creators, build playlists, save videos for later, and set up customizable notifications or a personalized email newsletter so you never miss new content from the voices you care about.^3
The platform is independent and lay-run, founded by Matthew Harvey Sanders with a simple rule for every creator on the roster: be faithful to the Church.^2 Beyond aggregation, the long-term vision includes self-hosted content with comments and discussions — a space where Catholics can actually interact with each other around the ideas that matter.^2
Christendom also features Shorts, a news category, a music section with daily Liturgy of the Hours, and a curated shop with Catholic goods from artisans like CeCeAgnes Rosaries.^1 The app is free on iOS, Android, and Microsoft Store, with the full web experience at christendom.app.^4
Notable- Built by Longbeard Creative Inc., also creators of Magisterium AI, Vulgate AI, the Alexandria Digitization Hub (with the Pontifical Gregorian University in Rome), and Ephrem AI — a suite of Catholic Specialized Language Models (SLMs) in development^6
- Featured by Forbes (May 2026), Wall Street Journal, Business Insider, EWTN, and the Cognitive Revolution podcast^7
- Longbeard founded the Builders AI Forum (BAIF), a 501(c)(3) nonprofit bringing together AI leaders and Catholic Church leadership; the November 2025 BAIF gathering at the Pontifical Gregorian University drew ~200 leaders from 160 organizations and received a formal message from Pope Leo XIV^7
- In 2026, Longbeard's Vulgate AI platform partnered with The Catholic Herald to digitize and index its 137-year archive of Catholic journalism^10
