Hey Product Hunt 👋 I built CastWeave AI because changing dialogue in video/audio is still painful. You can edit a transcript easily, but keeping the same character voice, tone, and scene consistency is much harder - especially for creators, podcasters, dubbing workflows, short films, and post-production fixes. CastWeave AI lets you upload video or audio, detect speakers, map them to characters, edit transcript lines, assign or generate voices, and create clean replacement dialogue audio. The goal is to make dialogue rewriting feel more like editing text - but with the voice and character still intact. Would love feedback from creators, editors, podcasters, and anyone working with voice/video content.
