What Vosuba is
Vosuba is a Mac application for transcribing video, styling captions, burning subtitles into footage and creating voiceovers. Its editor uses Whisper transcription with emotion detection, speaker separation and caption-compliance checks. You can export SRT, VTT or ASS subtitle files, or burn captions directly into video. Batch processing applies selected styles, models and export settings to folders of videos. Voiceover Studio provides 26 neural voices, voice cloning from an audio sample, speech controls and WAV or MP3 export. The maker says files remain on the Mac without cloud uploads, data collection or telemetry; license activation makes a network request. An accessibility dashboard checks captions against WCAG 2.2, ADA, FCC and DCMP standards and requires Creator or above. Vosuba requires macOS 13 Ventura or later on Apple Silicon. Plans range from a free tier to Creator, Pro and Enterprise.
