The big pictureWhat is ToAll

A pipeline for every language, in real time.

Outreach & strategyWho ToAll serves

Three audiences,
one shared message.

ToAll was built to serve the people already working to share the gospel across languages — and the independent voices who carry it into new communities.

01Within the Church

Where the message originates

Translation departments, missionary work, stake and ward broadcasts, area presidencies — the operational core of multilingual outreach.

03Independent Advocates

Voices outside official channels

LDS content creators, podcasts, faith-based broadcasters and translation ministries — champions who can carry ToAll into communities first.
