Per-character voice routing
Assign Tobin’s baritone to your antagonist, Mara’s lilt to your protagonist. AI Book Generator reads your manuscript’s dialogue tags and switches voices on cue.
Stale-chapter detection
Edit a chapter and AI Book Generator marks the audio stale — one click to regenerate only the affected chapter, not the whole book. Saves real money on long manuscripts.
Per-chapter MP3 export
Per-chapter MP3 plus a single-file variant. Export and upload to your distribution platform of choice.

English-native narrators in five tone families — Calm, Dramatic, Warm, Energetic, Bookish. Three premium voices are exclusive to the Studio plan.
