Images, audio, video, PDF — broadcast live.
Images, audio, video, PDF — synced to every listener. CAST runs alongside STAGE or DIALOG: what you explain, everyone sees and hears at the same time — in their language.
How it works
Three steps. Pick the file, send it, everyone sees it in sync.
Prepare a file
Upload images, audio, video or PDF in the speaker app — or drag and drop. Preview right away.
Send with one tap
The send button pushes the file to every connected listener at once — whether five or five hundred.
Sync playback
Content appears on every listener device at the same moment, with subtitles in their chosen language.
Who uses CAST
Five typical companion settings — always paired with STAGE or DIALOG.
You explain a landmark — and ship the historic photo or old map at the same moment. Visuals and audio, exactly when needed.
Slides synced to every smartphone, not just the big screen. Program updates pushed live.
Datasheets, product videos and price lists straight onto every visitor's listener device — in their language.
Slides, audio examples and handouts shared instantly. Students follow along, in their language.
Hymn lyrics, reading visuals and anthems in sync with the sermon. International communities stay connected.
