Show HN: RainbowSay – Learn, teach, research languages live with shows you love

RainbowSay is a new macOS application designed to help language learners by transcribing and translating dialogue from streaming media in real-time. The app pauses video content at the end of sentences to provide vocabulary, grammar notes, and word-by-word highlights.
Why it matters
It represents an innovative application of AI-driven transcription and educational tools to enhance passive media consumption for language acquisition.
RainbowSay listens along with your favorite series, videos and podcasts. It pauses at the end of each sentence and shows you what was just said — translation, vocabulary, grammar. Real voices, real pace, one sentence at a time.
