( For narrative shows )
Score the story, not just the intro
A narrative episode is chapters, and chapters want music that changes with them. In Cast the structure lives in the transcript — mark the beats where the story turns — and the music is generated per section, in parts, ducking under the narration on its own.
Produced is a texture, and it is buildable
What separates a produced narrative show from a read-aloud essay is texture: a bed that enters when the scene changes, a sting on the reveal, silence used on purpose. Cast generates each of those pieces to order — a looping bed, an intro/outro, a short sting — and sound effects described in a sentence.
The mechanics stay out of the way: chapters mark the structure, the duck follows the narration through every re-edit, and stems keep each layer separately adjustable to the end.
- Chapters as story beats
- Beds, stings and SFX to order
- Ducking survives re-edits
- Every layer stays separate
FAQ
01How do I add chapters with timestamps?
Select the text where a chapter should start and mark it (⌘⇧M) — the title comes from your selection. Chapters export as timestamp lists for YouTube and for Podcasting 2.0.

Describe what you want, pick what kind of track it is — a background bed that loops, an intro/outro, or a short sting — and Cast generates an original track for the episode. It is generated for you, not pulled from a catalogue other shows are also using.
Read more →03How do I add sound effects?
Describe the sound and Cast generates it — a whoosh, a transition, an ambience. Ask for up to four variants in one run and keep the best.
Read more →04Why does the music duck under the narration?
That is auto-ducking. The music drops under the voice and comes back in the gaps, automatically — and because the duck follows your actual voice clips, it stays correct after you cut. Trim a minute of filler and the music re-balances itself. You never draw a volume envelope by hand. You can set how far it drops, or switch it off.
