ACE listens.
You present.

Plays nicely with the rest of your rig
One app, every live event
Built for any room where someone speaks and slides need to follow them.
What ACE actually does
Local-first, latency-conscious, built for the kind of pressure where mistakes are visible.
Listens to live audio
Microphone or NDI in. Whisper transcribes locally on your device — your audio never leaves the room by default. Sub-second latency on M-series Macs.
Detects what's being said
Songs, scripture, conference talks. Vector search matches transcripts against your library in real time.
Outputs anywhere
Fullscreen HDMI, NDI to ATEM, ProPresenter passthrough, browser-based stage monitor.
Built for live
Survives Wi-Fi drops, audio device swaps, and the occasional shouted prayer.
Voice control
"Next slide", "clear", "Bible mode on". Operator hands stay free.
Update prompts
When a new version ships, ACE shows a download prompt on launch and hands off to your browser — no surprise installs mid-service.
v1.5 — Service Plan,
bilingual songs
Build the order of service, run it live
Songs, scripture, prayer, announcements — drag them into a plan, activate, and tap Go. The whole tab was missing its backend until now; v1.5 fills it in with proper persistence, single-active-plan invariant, and a Go handler that pushes through the same display engine your manual cues use.
Songs that switch languages, followed correctly
Settings → Audio → Language → Auto-detect. Whisper runs in multilingual mode (no longer locks to the first language it hears) and Deepgram nova-2 handles code-switching natively. English+Spanish, English+Portuguese, English+French — your team can switch verses mid-song and the lyrics keep up.
Audio joins songs, slides, and bibles in ⌘I
MP3, WAV, M4A, AAC, OGG, FLAC, AIFF — all flow through the same import wizard now. The Audio Bin becomes a player + manager, no separate uploader. One discoverable path for everything.
Imported slides reach the audience even with media on
Was: double-click an imported PPTX slide, it shows in Program but the HDMI screen keeps the worship loop. Now: slide-image is its own render layer above background media, just like the operator's preview pane already worked.
- F2 / Clear Slide now clears lyrics + slide background as one cue
- Foreground video plays its audio — background loops stay muted to preserve the live PA
- Audio Bin per-row delete with confirm + path-traversal-guarded backend
- Sermon Recording — live transcript visible by default + transcripts counter
- Genius song import is snappy — modal closes immediately, toast tracks the round-trip
- Song-edit lyric changes reflect immediately across the dashboard, no click-away
- LIVE badge no longer sticks on the previous song after detection moves on
- Settings → Cancel, Permissions wizard → Open Settings, Sermon → Export buttons all work
- LibreOffice deferred-install no longer false-positive-reports as installed after a partial download
- Library sidebar tidied: redundant 'Import' text removed, + button stays for Genius search
Full release notes live in-app under Settings → Updates.
