Live multi-machine slide sync

Every screen,
in perfect sync.

KueSync keeps Keynote and PowerPoint in lockstep across any number of Macs and PCs — drive the fleet from Bitfocus Companion, machine-to-machine from a presenter remote, or any phone. Builds, animations, timed cues, loops, and live failover.

Each screen its own image — locked to the same slide, the same instant.
KueSync is live multi-machine presentation sync for Keynote & PowerPoint — it is not a file-sync or backup tool, and is unrelated to QNAP Qsync.
What it does

Everything a multi-screen show needs

Drive the whole fleet from Bitfocus Companion, a presenter remote, or any phone — with builds, video, cue lights, and automatic failover. Built and hardened on real multi-machine shows.

Macs & PCs, one button

Drive any number of presentation machines — Mac or Windows, Keynote or PowerPoint — from a single connection. Every cue fans out in lockstep.

Builds & animations

Every machine steps through in-slide builds and animations together — not just slide numbers. Press once, all screens advance one build.

Frame-tight sync

Every screen flips together within a couple of milliseconds — instant, consistent, and dialed in out of the box. No tuning, no drift.

Failover that doesn't flinch

Nominate backups by priority; if a machine drops, control fails over automatically and a recovered primary only reclaims once it's provably stable. As dependable as a hardware cue system — over the network.

Cue lights, built in

Turn Stream Deck keys into a PerfectCue-style cue light — green on a forward move, red on a back — mirroring the presenter's clicker. One key, or tile a whole panel.

Phone as a remote

Any phone becomes a wireless advancer from a scannable link — no app. Hand the cue from speaker to speaker, and a master can take control at any time.

Loops & timed cues

Roll the deck continuously, hold a slide for an embedded video, or auto-advance on a per-slide cue sheet — synced across the fleet.

Loads when you need it

The agent installs in seconds, bundles everything it needs, and stays out of the way — it runs only when you open KueSync, with an optional launch-at-login toggle.

Your network, your rules

Run show control on the subnet you choose — a dedicated LAN, the house network, or a direct self-assigned wire through a switch. KueSync listens and discovers everywhere; traffic rides the wire you picked.

How it works

Two pieces, one workflow

1

KueSync Agent

A tiny app on each presentation Mac. It drives Keynote / PowerPoint locally and reports live status. Self-contained — install and forget.

2

Companion module

Add one KueSync connection in Bitfocus Companion, list your Macs' IPs, and drop the ready-made buttons onto a page. Every press drives the whole fleet in sync.
