☠️ Killian takes your AV dead serious.
Hi, I’m Killian.
I’m your backstage reaper. I run the lights, the sound, the screens and the camera. So you can stop operating your show and actually perform it.
Here’s the deal: you build your cue list, and I stand by. You hit GO. Or say the word, or hold up a prop. And I fire whatever’s next, dead on your beat. No laptop op. No missed cues. No mercy.
One button. Your whole show. I’ve got the rest.
Everything a cue can be
One cue list runs the show. GO fires whatever’s next. A slide, a song, the camera, a transition, a name bar, a QR code. And Killian keeps your place.
One cue list, one GO
A single ordered list of cues. GO fires the next one; BACK just re-arms. Cues auto-chain, so one tap can run a whole sequence on its own beats.
A real audio engine
Fades, crossfades, per-cue level trim and stacked simultaneous tracks. Plus a dedicated Kill Audio button for when you need silence now.
Cinematic transitions
Crossfade or dip-to-black between any two cues. Slide into camera, song into song, scene into scene. No ugly hard cut. It looks like broadcast TV.
Broadcast name bars
Lower-third title cards and live text, straight from a cue. Name your guest, title the bit, throw a score or a callout on screen like a TV graphics op.
QR cue, instant crowd
Fire a QR onto the big screen and the whole room scans at once. A poll, your socials, a mailing list, a tip jar. Turn the back row into a follow, or a sale.
Live camera + HDMI out
Push slides, videos or a live camera feed to a big screen over HDMI. Multiple cameras, live zoom, Continuity and USB-C capture all supported.
Slides & overlays
Import PDFs or images as slide cues, then stack graphic and big-text overlays on top. Health bars, score, callouts, framed borders, all on a cue.
Learn any remote
Teach Cue Killer any 3-button clicker. GO / BACK / LIVE, with single, double and hold each mapped. Flic and Bluetooth supported. Hold to panic-blackout.
Your confidence monitor
Your screen always shows what’s live, what’s armed next, and what each button does. Nothing is memorized, and you never lose your place.
Fire a cue, your way.
Your hands are full and your eyes are on the audience. So a cue can fire however the moment needs. Your voice, a prop you hold up, any remote you like, or even a phone you hand across the room.
Say the word
Assign a spoken phrase to any cue. Turn listening on and the moment you say it. Mid-sentence, on stage. The cue fires. It hears you over the show’s own music, and when phrases overlap the most specific one wins.
Hold up a prop
Show the camera a card, a prop, an object. Cue Killer recognizes it and fires its cue. It locks onto the thing in frame and waits for a steady match, with a strictness dial so it triggers on the right cue and nothing else.
Bring any remote
Prefer a button? Teach it to Cue Killer. Press it once and it learns the signal. Map GO, BACK and LIVE, and give single, double, and hold each their own cue. Works with Flic and any Bluetooth presentation remote.
Hand it to the room
Spin up a private control page on the spot. Anyone you hand the link and pairing code can fire cues from their own phone. An assistant in the wings, or a spectator about to do something impossible.
Stop waiting on Ralph from HR.
Need a hype intro? A walk-on track? A title card, or a whole opening number? Don’t beg the AV guy and don’t settle for the crappy voiceover. Tell Killian what you want and he generates it, right in the app, in seconds.
Voiceovers on demand
Type the line, pick a voice, get a broadcast-ready intro. No more Ralph reading it flat off a sticky note.
Music & stings
Generate walk-on music, beds and stingers on the spot, in any style. Drop them straight onto a cue.
Title cards & backgrounds
Describe it, get the image. Name bars, slides and backdrops without hiring a designer.
Voice changer & clone
Turn any recording into any voice. Clone a voice once and use it across the whole show.
SFX & clean audio
Conjure sound effects from a prompt, and strip background hiss out of a recording with one tap.
Build the whole show
Describe your show in a sentence. Killian drafts every cue: slides, music beds, camera cuts, name cards, transitions, timing. Then you tweak it.
Powered by your own AI keys (ElevenLabs, Suno, OpenAI). Stored on your device, never shared. Killian just does the asking.
Turn the back row into the show.
Fire a QR on the big screen and the whole room is in. Live polls, a pick-a-number guess, a word cloud that builds itself out of the crowd. They join from any phone, on any network. The results animate live on screen, in your colors.

No app to install. They scan, they tap, they’re in.
Live poll
Two to four choices, bars that fill in real time. Let the room pick the encore, the ending, the next bit.
Pick a number
Everyone guesses inside a range. The big screen reveals the most-picked number and the running average. A magician’s dream.
Word cloud
Ask anything. One-word answers swarm in and the crowd’s favourite grows biggest, right on screen.
Six built-in looks, or set your own gradient, accent and logo. Brand the join page and the big screen to match your show in seconds. After a vote you can even bounce the crowd to your link, your tip jar or your socials.
See it in action
Real screens, straight from the app. Built so one glance tells you everything.

Every show, color-coded
Your whole season in one place. Each show keyed to its own color.

Everything a cue can be
Video, slides, QR, lower thirds, live text, camera, audio. One menu.

Fire it hands-free
A spoken word, a prop on camera, an NFC tap or OSC. Per cue.

Generate it in the app
Voice, music, sound effects and images. Made on the spot.

One screen, total control
GO, BACK, LIVE and every action a single tap away.

One shared library
Slides, audio and video. Rename, search and reuse across every show.
“The best I’ve ever seen. By far.”
Matt breaks software for a living. They call him Crash. He spent two weeks trying to break me, then filmed this instead.
“I’m starting to have trouble breaking it… if you know anything about me, you know this is HIGH PRAISE.”

Built for the one running it alone
No booth. No op in the back. No crew on headset. Just you on stage and Killian in the wings.
Magicians
Fire the reveal with a word or a prop while your hands stay in the trick.
Musicians & DJs
Backing tracks, crossfades and visuals, all run from the stage between songs.
Speakers
Slides, lower thirds and a tip-jar QR, all without a clicker babysitter.
Comedians
Stings, callbacks and bits land on your beat, not the tech’s reaction time.
Worship & events
Lyrics, video and cameras to the big screen with one volunteer, not a team.
Theater & busk
A full sound and screen cue stack that fits in your bag and sets up in minutes.
Pro show control, without the pro rig
Tools like QLab and ProPresenter are incredible. For a full crew with a Mac and a booth. Cue Killer is for the performer running it alone.
