On-device, always private

Meet Hello C.

An AI Bible assistant that runs entirely on your phone: no server, no internet connection, no account. Ask it anything about the Bible, Ellen White's writings, or the commentary already downloaded in the app, and it answers from that material specifically and tells you exactly where the answer came from.

01Downloads once (~800 MB), then never touches the network again
02Answers only from the Bible, EGW, and commentary already in your app
03Always cites its sources: verse, book, or commentary reference

Early access

Get AdventCompass before it's on Google Play.

The Play Store listing is in review. In the meantime, grab the Android APK straight from GitHub Releases: same app, same offline AI, no waiting.

Download APK (GitHub) Google Play, coming soon

Android will warn about "unknown sources" for a direct APK install: that's expected outside the Play Store. Allow it for this file once, from your downloads.

2Open it and allow install from this source

3Launch AdventCompass, then download the AI model whenever you're ready

Questions

Good to know.

Yes. the Bible, EGW's writings, the commentary, hymnals, and (once downloaded) the AI assistant all run entirely from your device. You only need a connection the first time you download the app, the AI model, or a new Sabbath School quarter.

The Play Store listing is currently in review. Rather than make early users wait, the APK is available directly from GitHub Releases in the meantime: it's the exact same build.

No. Hello C runs a small language model directly on your phone. Nothing you ask it ever leaves your device: there's no server it could send data to even if it wanted to.

Only the Bible, Ellen G. White's writings, and the SDA Bible Commentary already stored in the app. It's told never to invent an answer from outside knowledge: if the app's content doesn't cover something, it says so plainly instead of guessing.

Android is the initial release. An iOS build is on the roadmap once Android is stable on Google Play.
