Hey PH! Mehdi here, builder of Overline.
The idea came from watching live news coverage with human interpreters doing real-time translation. They miss things, they slow down, and they're not available on a random YouTube video at 11pm. I thought this should be a solved problem, so I built it.
The hardest part was latency. Most transcription tools batch audio into chunks and upload them, you get a 5–10 second lag. Overline streams audio directly so captions appear as words are spoken.
It's been on the Chrome Store for a few weeks, ~2,000 users so far. Happy to answer anything. And if something breaks, tell me here, I'll fix it fast. :)
