What do you use a teleprompter for?

I built CueSpot after recording job application videos and constantly losing my place in my notes. Since then I’ve heard from people using it for YouTube intros, sales demos, talks and even wedding speeches.

I’m curious what you’d use it for, and what’s the one thing that always annoyed you about other teleprompter apps?

I’m picking the next features based on what comes up here.
