Turn one video into subtitles for more viewers.

Upload subtitles or start from audio, then localize your video with natural phrasing and channel tone.

Localize your channel while keeping your voice

Expanding your YouTube audience internationally shouldn't mean turning your dialogue into robotic, textbook captions. When translations sound stiff or miss the humor, international viewers click away.

Mitsuko adapts your subtitles to 100+ languages while preserving your channel's unique energy, pacing, and colloquial style.
