Scripture on screen,
as the word is spoken.
Sapphire listens to the preacher and puts the verse on screen in under a second. It understands “the next verse,” “first John,” and a verse read without a citation — and it knows when it isn’t sure, so it never guesses on your screens.
For all have sinned, and come short of the glory of God;

It knows which verse you mean.
Every phrase goes through the same three steps: find the reference, rate how sure it is, decide what reaches the screen. Confident matches go live on their own. Everything else waits for you.

0/502 — Operator console
Auto when it’s sure. You, when it isn’t.
Two monitors, like a broadcast switcher. Preview is yours to stage; Program is what the room sees. When you’re confident, mirror mode takes Preview live the instant it lands.
Fear thou not; for I am with thee: be not dismayed; for I am thy God.

Congregation alerts
Fire a scrolling banner — “Parking closes at noon” — across your displays without disturbing the verse on screen, and keep it off any feed you choose, like the livestream.
Voice commands
It understands spoken commands mid-sermon — “next verse,” “clear the screen” — straight from the pulpit. Teach it your own phrases and it learns those too.
Keyboard-first
Take, clear, re-present, next-in-queue — every action has a shortcut so your hands never leave the keys.
03 — Read aloud
The verse, read aloud. The mic ducks itself.
Sapphire can also read each verse aloud to the room. The moment it starts, it ducks the live mic so the two never fight — then hands the floor back.
Sapphire voice (~337 MB, downloaded on demand) or your system voice.
Therefore, brethren, we are debtors, not to the flesh, to live after the flesh.
04 — Outputs
It speaks NDI, OSC, and REST.
One session, every rig. Publish verses as a clean NDI source, take cues over OSC, or drive it from a Stream Deck — anything that can hit an HTTP endpoint.
