Onyx
Your teleprompter, hidden in plain sight
Onyx is a macOS teleprompter and speed-reading app that lives in your screen's notch. Follow along with real-time speech recognition in Teleprompter mode, or train your reading speed with RSVP in Speed Reader mode. Everything is processed locally on your device — no cloud, no accounts, no data collection.
Two powerful modes, one seamless experience
Teleprompter
Real-time speech recognition follows along as you speak, highlighting each word in your script so you never lose your place.
Speed Reader
RSVP mode flashes words at your chosen pace — configure WPM and chunk size to train yourself to read faster.
File Import
Drag and drop .txt, .md, or .pdf files directly into the app, or paste text from your clipboard.
Multi-Monitor
Choose which display shows the overlay — perfect for presentations where your notes stay on one screen.
Privacy First
All speech recognition and text processing happens entirely on your device. No data ever leaves your Mac.
Customizable Overlay
Adjust the overlay's width, height, colors, opacity, and blur to match your setup and personal preference.
