The dialogue editor video creators deserve
CastWeave was born from a simple problem: dubbing and re-voicing video is painful. Existing tools either lack character awareness, ignore voice consent, or force creators into clunky workarounds. We built CastWeave to fix that — a focused workflow that takes you from raw footage to export-ready dubbed audio, with full control over every line.
What we believe
Consent-first voice use
Every voice workflow in CastWeave is designed for content you own, have licensed, or have explicit consent to use. We never enable unauthorized voice cloning.
Character-aware editing
Unlike generic audio tools, CastWeave understands your cast. Map speakers to characters once, and every line stays in sync across scenes and exports.
Built for video workflows
CastWeave is purpose-built for video dubbing. Import footage, detect speakers, transcribe, rewrite, regenerate, and export — all in one guided workflow.
Per-line voice control
Attach specific voices to characters and regenerate individual lines without re-recording entire scenes. Every take is export-ready in WAV or MP3.
AI-powered, human-directed
AI handles the heavy lifting — transcription, speaker detection, line generation — while you stay in control of creative decisions and final output.
How CastWeave works
CastWeave organizes video dubbing into five clear steps. Each step preserves your cast, voices, and line continuity — so nothing gets lost between edits.
- 1
Import media
Upload your video or audio file. CastWeave extracts the audio track for processing.
- 2
Detect speakers
Automatic speaker diarization identifies who speaks when, how many speakers are present, and how many lines each has.
- 3
Build your cast
Map detected speakers to named characters. Attach a voice to each character from your voice library.
- 4
Rewrite or regenerate
Edit any dialogue line. Regenerate the audio take using the character's assigned voice — with per-line control.
- 5
Export clean takes
Download export-ready WAV or MP3 files for individual lines, full scenes, or complete projects.
