PROMPTER

...and that brings us to the core of the presentation.

The future of public speaking is not about memorization.

It's about clarity and confidence.

When you free your mind from remembering lines,

you can focus entirely on connecting with your audience.

FEATURES

001

SPEECH-TO-TEXT AUTO-SCROLL

Choose between Apple Speech or WhisperKit for on-device voice recognition. Prompter listens and scrolls in real time. No foot pedals. No remote controls. Just speak.

002

REAL-TIME VOICE ALIGNMENT

Intelligent transcript alignment matches your spoken words to the script. If you pause, the teleprompter pauses. If you skip ahead or go off-script, it catches up with configurable smoothing.

003

VOICE ACTIVITY DETECTION

Built-in VAD distinguishes speech from silence. The prompter holds position during natural pauses — no unwanted drift during turn gaps or breathing room.

004

NOTCH-CONNECTED WINDOW

A custom window shape with inverted corners that flows seamlessly from the macOS notch/menu bar. Maximizes usable screen real estate with a design that looks native.

005

THREE OBSESSIVE THEMES

Midnight: deep navy with cyan accents. Dark: pure black with white text. Light: warm off-white with blue highlights. Each tuned for readability under studio lights, sunlight, or late-night sessions.

006

MULTI-DISPLAY & FOLLOW CURSOR

Pin the prompter to any connected display or let it follow your active screen automatically. Left, center, or right alignment. Adjustable width and height.

QUESTIONS

Do I need an internet connection?

No. Both Apple Speech and WhisperKit run entirely on your Mac. Your voice data is processed locally and never leaves your device.

Is this really free?

Yes. Prompter is open-source software under the MIT license. No payments, no trials, no feature gates. Download it, use it, modify it.

Does it work with external microphones?

Yes. Any microphone recognized by macOS works seamlessly — USB, XLR via interface, AirPods, built-in mic, whatever you have.

What's the difference between Apple Speech and WhisperKit?

Apple Speech uses the built-in macOS speech framework with zero setup. WhisperKit runs OpenAI's Whisper models locally for higher accuracy — download a model in Settings to use it.

Can I use it for live streaming?

Yes. The compact, notch-connected window and adjustable sizing make it work well alongside OBS, Zoom, or any recording setup.

What are the system requirements?

macOS 14.0 (Sonoma) or later. Apple Silicon or Intel. Microphone access for speech tracking.
