The online teleprompter scrolls your script at an adjustable speed, with full-screen and picture-in-picture display modes and a mirror text option for use with reflective prompter hardware. It is most useful for video recording, live streaming, or rehearsing a speech where reading from a screen is preferable to memorization.
Speed calibration before recording
Speed is measured in characters per second. Typical Mandarin news delivery runs at 3–5 characters/second; English speech at around 10–15 characters/second is roughly comparable. For English-language scripts, start around 10–12 and rehearse once at a slightly slower speed before recording to confirm the pace feels comfortable. Setting speed too high leaves no recovery time if you stumble — lower speed creates more margin.
Highlight zone size
The highlight zone (measured in lines, default 3) shows which part of the script is currently "active." Smaller zones (1–2 lines) help your eyes lock onto the current sentence, similar to traditional prompter hardware where the reading line is a fixed narrow band. Larger zones give more context but reduce the focus effect. If you are using a physical reflective teleprompter, reduce the zone to 1 line to match the narrow reading strip.
Picture-in-picture for screen recording
Clicking "Picture-in-Picture" opens the script in a floating window detached from the main browser tab. This is useful when recording your screen with OBS or similar software — you can position the floating window outside the capture area so it does not appear in the final recording. You can also move it to a second monitor if one is available.
Pre-roll countdown
Enabling the countdown displays a configurable number of seconds (default 5) before scrolling begins. This gives time to adjust posture, take a breath, or wait for recording equipment to be ready. The countdown can be cancelled with the spacebar at any point before it hits zero.
Mirror text
Mirror mode flips the text horizontally so it can be read in a half-silvered reflective mirror mounted in front of a camera lens. If you are reading from a regular monitor placed directly in front of you, this option serves no purpose and makes the text unreadable.
