About this tool

Pocket Teleprompter is a phone-friendly teleprompter for video recording, speeches, and presentation practice. Paste a script and let it auto-scroll at the selected speed.

In addition to manual speed control, target-duration mode can calculate scrolling so the rendered script reaches the end in a chosen time. Mirror mode supports beam-splitter rigs, and an eye-line guide helps keep attention near the camera.

Good for

Limitations and notes

Target duration controls scrolling time; it does not measure your actual speaking pace through the microphone.
Screen Wake Lock and Fullscreen API availability depends on the browser and how the page is opened.
Very long scripts can increase browser memory usage.
On shared devices, clear the saved script from LocalStorage after use.

Frequently asked questions

Is my script uploaded to a server?

No. Editing, scrolling, and storage happen in the browser, and the script is not uploaded to Browser Kitty.

Can it scroll a script to fit a three-minute duration?

Yes. Target-duration mode calculates scroll speed from the rendered script length so it reaches the end at the selected time.

Can I use it with a mirrored teleprompter rig?

Yes. Mirror mode flips the script horizontally for beam-splitter setups.

Can it keep the screen awake?

On supported browsers, Screen Wake Lock can keep the display awake, though availability varies by device and browser.
