Many churches today are more diverse than ever, with members speaking dozens of different languages — yet most sermons are delivered in just one. Kaleo AI is a real-time church translation and captioning platform that lets every attendee follow along in their own language, right from their phone.^1
When a pastor speaks, Kaleo AI transcribes and translates the sermon into 150+ languages simultaneously. Church members simply scan a QR code or search for their church in the app, then read captions or listen through headphones — no special hardware required.^1 What sets Kaleo apart from generic translation tools is its custom training on theological terminology and biblical names, so "epistle" doesn't become "a pistol" and proper nouns like Deuteronomy and Elisha come through accurately.^1
Founded by Aidan Britnell, a University of Toronto computer science graduate and Schulich Leader Scholarship recipient, Kaleo AI was born from a real need at his home church in Oakville, Ontario, where over 70 languages were represented but only Spanish translation was available.^9 Britnell previously worked as a Cyber Security Architect at Hatch Engineering before pursuing Kaleo AI full-time.^9 "Language should never be a barrier to hearing the gospel," Britnell said at the platform's launch.^2 The app also serves deaf and hard-of-hearing congregants with live captions in the original language and Bluetooth hearing aid compatibility, with plans to expand into American Sign Language (ASL).^3 For members without a smartphone, churches can loan a device or use a special radio receiver so no one is left out.^10
Why Churches Love It"Church members are bringing family members who've never attended because of the language barrier — and they're staying." — Aidan Britnell, Founder^2
