Teleprompter
Paste a script and read it to camera at a pace set in words per minute. Full screen, mirror mode for beam-splitter rigs, and a live estimate of how long it runs.
Runs in your browser
words (or Chinese characters) per minute
Space starts and pauses. ↑ and ↓ change the pace. Home goes back to the top.
For a beam-splitter rig, where the glass reflects the screen back at you the wrong way round.
Your script stays in this tab. It is never sent anywhere and never stored.
Set the pace in words, not pixels
Every teleprompter has a speed control and most of them measure it in something meaningless — a number from 1 to 10, or pixels per second, which changes meaning the moment you change the type size or the window width.
This one is set in words per minute, which is a number you can reason about and check against a stopwatch. Change the font size and the scroll rate changes with it, so the pace you set is the pace you get.
A comfortable read-aloud pace is around 140–160 words per minute in English. Broadcast news sits near 150. Under 120 sounds laboured; over 190 stops being followable.
Chinese is counted in characters
中文 has no spaces, so counting “words” would treat a whole line as one and run the script at roughly one two-hundredth of the right speed. Chinese is counted per character instead, which is also how the pace is normally quoted: a comfortable spoken pace is about 240–300 characters a minute.
Mixed text — which is most Chinese technical writing — adds up the way it reads: each Han
character is one beat, and Cloudflare is one beat. The Chinese pages default to 260, the
English one to 145.
The estimate above updates as you type, so you can cut a script to length before you record rather than after.
The reading line is a third of the way down
Not at the top, and not in the middle. A presenter reads slightly below their eyeline, and the line has to be far enough down that there is upcoming text visible above it — you read ahead whether you mean to or not. The marker shows where to look.
Mirror mode
A real teleprompter is a sheet of half-silvered glass at 45° in front of the lens: the camera sees through it, and you see the screen reflected in it. A reflection is left-right reversed, so the source has to be reversed too or the text comes out backwards.
Turn mirroring on only if you are using a beam splitter. Reading directly off a screen beside the camera needs it off.
Keyboard
| Key | Does |
|---|---|
| Space | Start and pause |
| ↑ / ↓ | Faster and slower, five at a time |
| Home | Back to the top |
Space is ignored while the cursor is in the script box, so you can still type.
The scroll is timed against the clock
Frames get dropped — a background tab, a busy machine, a browser deciding to throttle. A teleprompter that advances a fixed number of pixels per frame slows down when that happens, which is exactly when you need it not to.
This one measures the real time since the last frame and moves the distance that time is worth. A dropped frame costs a little smoothness and no time at all.
Privacy
Your script stays in the tab. It is not uploaded, not saved to storage, and not recovered when you reload — which is deliberate for something people paste sensitive drafts into. Copy it somewhere you keep things before you close the tab.
