LumeSub — Real-time translation subtitles for anything on your screen

  LumeSub is a macOS app that captures system audio, transcribes it live, translates
  it, and shows the result as transparent overlay subtitles. Watch videos or join
  online meetings in any language and follow along with readable translated captions
  — no matter which app is playing the sound.

  Built with the Meta Model API: Muse Voice Transcribe for real-time speech
  recognition (25 languages, auto-detect) and Muse Spark 1.3 for context-aware
  translation. The translation window splits finalized lines (upper, white) from
  in-progress streaming lines (lower, gray), keeps sentences on screen for a readable
  4–6 seconds based on reading speed, and retains previous sentences while new ones
  arrive — so late results are never lost and the display never flickers.

  Demo: one continuous take translating Japanese, Spanish, French, Chinese, Korean,
  and Arabic into English, live.
