Welcome to RheoCast
Official documentation for RheoCast, church presentation and live production in one app.
RheoCast is built for churches that want scripture on screen as it is spoken, without scrambling through Bibles, slides, or search boxes during a live service.
It also runs the rest of your service. Cameras, scenes, song lyrics, overlays, recording and the live stream itself are all in the same app, so one person at the back of the room can handle the whole thing.
The two tabs
The app is organised around two tabs at the top of the window.
| Tab | What it is for |
|---|---|
| Present | Everything that goes on the screen the congregation sees, scripture, song lyrics, sermon notes. This is where transcription and verse detection run. |
| Broadcast | Your live production console: cameras, scenes, overlays, audio mixing, recording, and streaming out to YouTube or Facebook. Free on every plan. |
Present is split into sub-tabs: Live (transcription and verse display), Songs, Notes, Service Plan (the plan your church made in ChurchCast), and Creator Studio.
Two different "live" controls. In Present › Live, Start begins transcription. It listens to the sermon. The Go Live toggle on the Display Preview sends scripture to your projector or second screen. Neither of those starts a stream. Streaming is Go Live in the Broadcast tab, which is a separate control.
What RheoCast does
| Area | What you get |
|---|---|
| Live detection | Spoken references like John 3:16 or Romans chapter eight verse twenty-eight appear as detection chips you can display instantly |
| Manual search | Find any verse by reference or by searching verse text |
| Song lyrics | Build a setlist, project verses and choruses, import your EasyWorship library |
| Sermon notes | Write and follow notes, page through them on the screen, pop them out to a second screen, send a sentence to air |
| Display output | Windowed preview, fullscreen projector, NDI, or browser overlay for OBS / vMix / ProPresenter |
| Broadcast | Cameras, screen capture, phone cameras, scenes, transitions, audio mixing, recording, and RTMP streaming |
| Bible translations | Eight translations bundled and fully offline; import your own (Pro/Ministry); premium licensed versions coming soon |
| Creator Studio | Corrected transcript, sermon summary, structured notes, 5-day devotionals, and social content |
Do I still need OBS?
No. The Broadcast tab does everything a church typically uses OBS or vMix for: multiple cameras, scenes you can cut between, lower thirds, recording, and streaming to a platform, so most churches move across and retire the second application entirely.
If you are migrating, you do not have to do it in one Sunday. NDI and browser source output let RheoCast feed your existing switcher while you change over, so you can run both until your team is comfortable. See Display & Output.
How a typical service works
- Before service. Select your microphone, choose a Bible translation, and open the display on your projector or second screen. If you are broadcasting, add your cameras and build your scenes.
- During service. In Present › Live, click Start to begin transcription, and turn Go Live ON to project detected verses. In Broadcast, cut between scenes and go live to your platforms.
- Present verses. High-confidence detections can auto-display, or you can click a detection or search result to send it to the output.
- After service. Open Creator Studio, pick the session, and generate follow-up content for your congregation.
Tutorials
If you would rather follow one job end to end than read feature by feature, start with the Tutorials: your first Sunday, scripture on the projector, streaming to YouTube, designing a lower third, notes on screen, and feeding OBS or vMix. Each is a numbered walkthrough with the reference pages linked where they help.
