Teleprompter

About Teleprompter

Teleprompter is a free, browser-based tool that scrolls your script smoothly upward at a pace you set in words per minute, so you can read it hands-free while filming or recording. You paste your text, set the speed, font size, line height and text width, then press Start to scroll — with a Mirror toggle for reading off teleprompter glass and a one-key fullscreen mode. It runs entirely in your browser using a requestAnimationFrame scroll loop and the Screen Wake Lock API to keep your display on, so nothing is uploaded and there is no signup.

How to use Teleprompter

1. Paste your script into the Script text box at the top (a sample script is loaded to start with).
2. Drag the Speed slider to set your reading pace from 40 to 400 WPM, and adjust Font size, Line height and Text width to suit your setup.
3. Toggle 'Mirror (glass)' if you are bouncing the screen off teleprompter glass, 'Flip vertical' if needed, and '3-2-1 countdown' for a lead-in before scrolling starts.
4. Click 'Fullscreen' (or press F) to fill the screen, then press 'Start' (or the Spacebar) to begin scrolling.
5. While reading, use the ↑/↓ arrow keys to nudge speed and watch the centre guide line; press 'Reset' (or R) to jump back to the top, and 'Pause' (or Space) to stop.

Frequently asked questions

Is my script uploaded to a server?

No. The teleprompter runs entirely in your browser — your script is read, scrolled, and counted locally on your device, and nothing is ever uploaded. Your speed and font settings are saved only in your browser's local storage.

Is it free and do I need an account?

Yes, it is completely free with no signup, account, or watermark.

What is the Mirror mode for?

Mirror flips the text horizontally so it reads correctly when you bounce the screen off a sheet of teleprompter glass mounted in front of your camera lens. There is also a separate 'Flip vertical' toggle; changing either one pauses scrolling so the text doesn't appear to spin mid-read.

How accurate is the WPM speed setting?

Speed in words per minute is approximate — the actual on-screen pace also depends on your font size, text width and language, so the tool maps WPM to a scroll speed and you fine-tune the slider (40–400 WPM, also adjustable live with the ↑/↓ keys) until it feels right.

Does the screen stay on while I'm reading?

Yes, where supported. While the script is scrolling it uses the Screen Wake Lock API to keep your display awake, and it re-acquires the lock when you switch back to the tab. It is best-effort and silently does nothing on browsers that lack the API.

Is there a limit on script length?

Scripts are capped at 500,000 characters. Everything runs on the main thread, so very large pastes are rejected up front to keep the page responsive; if you exceed the limit you'll see a warning and need to trim the text.
