Verbum
An offline Bible sanctuary with liturgy, read-aloud, and private study help.
Product thesis
Built for a specific user, with privacy as product strategy.
Verbum is a donor-funded Bible app for English, Spanish, and Portuguese readers. It combines an offline sanctuary reader, Catholic liturgical calendar, neural read-aloud, and on-device study assistance without ads.
Audience
Readers who want scripture, prayer rhythm, and study support without turning faith practice into an ad surface.
Privacy stance
Study assistance is designed to run locally, and the product is donor-funded instead of advertising-funded.
