Plan by class and date
Keep the recurring group separate from the dated lesson. Drag videos, audio, images, and approved links into order.
SELF-HOSTED · OFFLINE-READY · NATIVE TV
Every lesson,
ready on cue.
Build dated media playlists in a browser served by your own local server. Pair classroom TVs with a PIN. Download everything ahead of time—and keep teaching when the network does not.

BUILT FOR THE REAL ROOM
Live-event reliability.
Everyday-simple planning.
Download before anyone arrives
Each screen receives a versioned manifest, verifies local media, and reports failures while there is still time to fix them.
Pre-roll into countdown
Loop a welcome sequence, then begin a duration-aware countdown so its last frame lands precisely on class time.
Keep playing offline
Native players prefer verified local files and never interrupt active local playback just because the server disconnects.
Preview the actual cue
Review every media item and hear saved trims, fades, volume, loop behavior, and notes before it reaches the room.
Control it from a phone
Select a screen and media, then play, pause, seek, skip, or stop from a local browser saved to the home screen.
