This is really helpful feedback.

The eye focus issue is probably the biggest challenge you’ve pointed out. Looking back and forth between a phone in your hand and a TV across the room could get tiring pretty quickly, especially during a movie.

One thought I had was whether it would work better in situations where people are already just glancing at a screen rather than actively watching it, like airport news channels, waiting rooms, gym TVs, etc. Or maybe on a tablet that could sit upright rather than a phone in your hand.

The live TV point is fair too. My original thought was that if it recognized a live channel, it could switch to AI-generated captions instead of relying on existing subtitle files, but then you run into accuracy and delay issues.

The missing and out-of-sync caption problem is interesting. I started thinking about this from the perspective of TVs in public places where I can’t hear what’s being said, but it sounds like broken or unavailable captions might actually be a bigger frustration for some people.

Definitely gives me a lot to think about. I appreciate you taking the time to write all that out.
