Mirror Text Mode for Beam-Splitter Prompters
Beam-splitter prompters work by reflecting a screen off angled glass that the camera can see through. The text on the screen has to be horizontally flipped so the reflection reads correctly. Telepront has a one-click mirror text toggle that does exactly that, with no third-party tools and no fragile workarounds.
See It in Action
Beam-splitter teleprompters are the standard for broadcast and serious video work. A panel of partially mirrored glass sits in front of the lens at forty-five degrees, reflecting a screen below or above the camera. The talent reads the reflection while the camera shoots through the glass and sees only the subject. The trick is that the source screen has to display the script flipped horizontally so the reflection reads correctly.
Telepront includes a native horizontal mirror toggle that flips the entire script in real time. The font, the highlighted line, and the cursor all flip together, so what you see in the reflection matches what you typed. Toggle it on when you mount your Mac display or iPad into the rig, and toggle it off for normal on-screen reading.
Mirror plays well with the rest of Telepront. Voice tracking keeps scrolling at your pace because it works from the microphone input, not the visual layout. Adjustable scroll speed lets you fine-tune for the rig's distance to the talent. The floating panel can be dragged onto an external monitor or an iPad over Sidecar for a clean, dedicated prompter display.
Telepront is a native Swift Mac app, free on the Mac App Store, and runs entirely on-device. It supports macOS 14 and later on Apple Silicon and Intel Macs.

Set font weight a step heavier when mirrored; reflections eat contrast
Position the panel as high in the prompter screen as possible for an eyeline at the lens
Use voice tracking so you don't need a remote when the rig is built
Frequently Asked Questions
What does mirror text actually do?
It flips the script horizontally so when you look at it through a beam splitter's reflection, the text reads left to right normally.
Do I need special hardware?
Mirror text only matters if you use a physical beam-splitter prompter where the camera shoots through angled glass. For on-screen reading, leave it off.
Can I use mirror with my iPad as the prompter screen?
Yes. Drag the floating panel to your iPad over Sidecar, toggle mirror, and place the iPad in your beam-splitter mount.
Does mirror affect voice tracking?
No. Voice recognition runs on the audio input, not the visual layout, so flipped text still scrolls in time with what you say.
Is the mirror feature free?
Yes. Telepront is free on the Mac App Store with no paid tiers.
