Description
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.

Could you build this?
Yes It relies entirely on standardized Web APIs (`getDisplayMedia` for tab audio capture, WebGPU/Transformers.js for on-device Whisper, and Chrome's built-in translation API) wrapped in a lightweight web app.
