About this online teleprompter
Paste your script into the text box, pick a font size and scroll speed, then hit Start: the page goes fullscreen and the text scrolls upward at a constant rate (driven by requestAnimationFrame, adjustable live from 10-300 px/s), with pause / resume and a mirror-flip option.
Mirror mode suits DIY beam-splitter teleprompters built from half-mirror glass. A small toolbar at the top of the fullscreen view offers pause / resume and exit; pressing Esc also exits at any time. Great for video recording, live streams and speech practice. Your text stays on your device — nothing is uploaded.
