Mirror teleprompter online: flip text for teleprompter glass
Updated October 27, 2026 · Anthony Delmotte
Short answer. Teleprompter glass reflects the screen, so the text must be flipped horizontally to read the right way round. Tick Mirror in our free online teleprompter, lay the screen under the glass and read through it, straight into the lens.
Why the text must be mirrored
A teleprompter rig has a sheet of beam-splitter glass at 45° in front of the camera. The screen lies below it and the glass reflects it toward you, which flips the image left to right. Mirroring the text cancels that flip. The camera, behind the glass, doesn’t see the text at all.
Set it up
- Open the online teleprompter on the tablet, laptop or phone that will sit under the glass.
- Paste the script and tick Mirror (for a glass teleprompter).
- Press Start and place the screen under the glass, text facing up.
- Control the speed from a keyboard, or let it follow your voice.
Which screen to use
A tablet is the usual choice: big enough to read from a few feet away, light enough for a small rig. Turn the brightness to maximum: the glass reflects only part of the light.
