Screens
Display Node fullscreen on the TVs you assigned. Stage follows Audience unless you hold Stage only. Room waits until you send. Stream overlay is text over camera in OBS; pictures and videos fill house Program.

Stage
Speakers and performers see the next line and the clock. The audience only sees the finished slide. That split is the whole point of the desk.

Text on screen
A speaker name, a score, a welcome, or a verse — without rebuilding a PowerPoint. Type it, check it in Practice, send it. Scripture lookup is there if the event needs it.

Tools for every industry
Same Send. Same practice pane. Different rundown. One operator can cover the hall, the stage, and the people watching online.

Keynotes, breakouts, and sponsor slides without rebuilding a deck mid-session. Names and titles go up in seconds.

Line-by-line lyrics, lower thirds, and a countdown to doors. Change the next song without touching what’s already live.

Scores, names, and announcements on the board and the stream. Fast enough for timeouts. Clear enough for the crowd.

Assemblies, graduations, and classrooms that need a projector and a livestream — without a fragile office slideshow.

Overflow rooms, lobby feeds, and a separate frame for online. One send, or a different layout if the stream needs it.

Feed the livestream from the same desk as the hall. The next slide stays on the laptop until you send — nothing leaks on air.
What you can expect
Simple mode is pick and go live. Careful mode adds Practice so volunteers can check a slide first.
The audience only sees what you send. The next lyric, name, or video stays on your laptop until then.
Venue plans include setup and a rehearsal. Not a download-and-hope install.
Skip an item, jump ahead, or start a countdown mid-show. The rundown is meant to change.

Test drive
Not a slideshow of screenshots. The same operator desk you would run a show with. Click through the browser demo on this site, or install the app for a 1 month full free trial — every live function — with no card up front. Your first bill is after the free month: ₱149 / month for students and teachers, or ₱399 / month (₱3,990 / year).
