Teleprompter for a mirror rig
Mirrored on screen so it lands right in your eye
If you use a beam splitter rig, Promter mirrors the text horizontally and vertically, independently, so the reflection lands readable on the glass. And it lets you control everything from the keyboard or a clicker, without breaking the take.
Why the text has to come out mirrored
On a rig, you're not reading the phone screen. You're reading its reflection in the angled glass, while the camera looks through that same glass and sees none of it.
Reflections invert. So the text has to leave the screen inverted to arrive correct in your eye. That isn't a preference setting, it's a requirement. A teleprompter without mirroring simply doesn't work on a rig.
Horizontal and vertical, separately
Almost every app has horizontal mirroring.
What's usually missing is independent vertical, and it matters because rigs don't share one geometry. Depending on how your equipment positions the device relative to the glass, the axis that needs inverting changes.
In Promter you turn both on separately and combine them however your rig asks. Set it once, it remembers.
You're in frame and mid-sentence
Even with the phone within reach, touching it during a recording costs something: you step out of frame, break eye contact or interrupt your sentence.
Which is why everything in Promter has a keyboard shortcut: play, pause, cycle the mic, calibrate, change reading position without pausing, font, width, mirroring, fullscreen, switch camera, record.
And a Bluetooth presentation clicker works right away, no setup. Promter understands PageUp and PageDown natively, which is what practically every clicker sends. You stay in front of the camera, hands free, and the prompter obeys.
The screen can't go dark. And it doesn't.
A phone dimming mid-sentence is the worst way to lose a take. Promter keeps wake-lock active while you present: as long as you're reading, the screen stays on.
Reading at rig distance
A rig changes the distance between you and the text, and that changes what's comfortable to read.
There are 6 font sizes and 7 text widths, adjustable live from the keyboard or the clicker, plus 4 reading styles: serif, clean, accessible and Roboto. The reading guide line is draggable and stays where you left it, so you can mark the exact height of the lens.
If your camera isn't the phone
Plenty of rigs use the phone as prompter only, with the recording happening on a DSLR, a mirrorless or a dedicated camera. That works perfectly: you leave Promter's camera off and use just the teleprompter.
And if you want the opposite, recording with the rig's own phone, Promter records up to 4K/60 with the text over the preview.
What it doesn't do
There's no remote control from another device. The clicker works as a keyboard, not as a companion app running on your second phone.
And Promter doesn't sell, recommend or configure hardware. It runs on the device you already mounted.
