A voice-over pipeline, not a black box.

Every step of the dubbing chain is visible and editable. Speech is recognized with OpenAI Whisper, translated, then synthesized as a natural voice-over and mixed over your original audio.

  • Voice speed and volume controls per output
  • Original audio kept underneath at your chosen level
  • Two-step mode: fix the text before any audio is made

Subtitles you can actually correct.

Machine transcription is a draft, not a verdict. Review every line with its exact timing, fix names and terminology, then burn clean captions into the video or download the SRT.

  • Line-by-line SRT editing before rendering
  • Burned-in captions or standalone SRT download
  • Original or translated language — your choice

From spoken word to any market.

  • Automatic source-language detection
  • YouTube and Facebook URLs processed directly
  • Editable translation before the final render
