Pipeline

From transcription to export,
all in one flow

Sentences you edit carry through to dubbing, and if the text and audio ever fall out of sync, we let you know first

Transcription — Extract text from audio instantlyUpload your file and get sentence-level, timestamped text. This text becomes the source for every step that follows.

Separation — Clean vocals even from outdoor recordingsRecorded outdoors? No problem. Voice and background sound are split into separate tracks, and only the clean voice moves on to the next step.

Editing — Edit text and regenerate only that segmentEdited sentences are marked for regeneration, with a preview of the expected length change. Nothing actually changes until you regenerate.

Dubbing — Translate and regenerate with the translated textTranslate the transcribed text into your desired language, refine the translation, then regenerate the dubbed voice from that text.
