Natural Captions® - AI with a human touch

Language is complex — more so when it's spoken. Accents, idioms, timing, tone — it all makes converting speech into fluent, brand-safe subtitles incredibly difficult.  That’s where Natural Captions® comes in. It’s CaptionHub’s proprietary NLP technology, purpose-built to make subtitles sound like they were written by people, not machines. It handles grammar, flow, punctuation, and pacing — across languages, at scale — so your teams spend less time fixing, and more time shipping.

  • Native fluency

    Designed to mimic how humans speak and write — so your subtitles feel natural, not robotic.
