FollowSpot
A teleprompter that listens, running Whisper on your own machine.
Read your script out loud and the highlight follows you. Skip a sentence, flub a word, or ad-lib a little and it keeps going. Stop talking and it stops too.
The listening is a whisper.cpp model you choose, served on 127.0.0.1, so your audio never leaves your laptop. I built it because I have the energy of a theater kid and can't memorize lines, and the prompter apps I had didn't let me pick the model or set up the screen the way I wanted.
how it works
01
Listen
Every quarter second, while you are talking, the page sends the last 3.5 seconds of audio to a local
whisper-server.02
Match
The transcript gets fuzzy-matched against the script around your place, so misheard words and ad-libs don't lose it.
03
Follow
The highlight moves and the page scrolls to keep your line at lens height. Click any word to jump there for a retake.

*[Wide shot. Lights up.]*
Hey, welcome back. Today I'm going to show you something I built
because I can't memorize lines.

A wide column makes your eyes sweep on every line. A narrow one centered on the lens hides it.
