ScriptAssist's scrolling PowerPoint teleprompter with the current words highlighted as the presenter speaks

A PowerPoint teleprompter that scrolls itself.

VoiceSync listens as you speak and moves your PowerPoint script with you, highlighting your current words as you go. Slow down, speed up, pause, ad-lib or take a question. VoiceSync stays with you.

VoiceSync Listening

Today, I want to show you three simple ways
to make your next presentation
clearer, more engaging,
and far more memorable.
Let's start with the first one.
It is the one most people overlook.

The script follows your voice, and pauses the moment you do.

No clicker. No foot pedal. No fixed scroll speed.

Turn VoiceSync on in Teleprompter Mode or On-Camera Script and simply start speaking. Your existing PowerPoint script follows along automatically.

100% on-device and private

Speech recognition runs on your own computer. Your microphone audio is never uploaded, recorded, or sent to any server, which is exactly what confidential and regulated material calls for.

Works offline, no Wi-Fi to depend on

Because nothing leaves your machine, VoiceSync keeps working when the conference Wi-Fi does not. Venue network, hotel network, no network... it makes no difference.

What changes the moment you turn it on.

Ordinary teleprompter	With VoiceSync
Scrolls at one fixed speed, and you keep pace with it	Follows your voice, at whatever pace you speak
A clicker or foot pedal in hand for every scroll	Nothing to hold, nothing to press, just talk
Racing to catch up, or waiting for the text to arrive	The words you are saying are always right in front of you
Cloud-based voice recognition may send audio off-device	Every word stays on your computer, never uploaded
