LiveSub

Maker of LiveSub, live tab subtitles

About

I build LiveSub, a free web app that turns the audio of any browser tab into live subtitles, Japanese ⇄ English. Speech recognition and translation run on your own computer, so nothing is uploaded and there is no time limit. I'm a solo maker, and I care about tools that respect privacy and don't meter what costs nothing to run. Feedback on where it breaks is always welcome.

LiveSub - Live subtitles for any browser tab, translated on-device

LiveSub turns the audio of any Chrome or Edge tab into live subtitles, English ⇄ Japanese. Speech recognition runs in your browser and translation uses Chrome's on-device translator, so audio never leaves your computer. Free, no install, no time limit.
