Long-form narration that stays consistent, chapter after chapter.
Chapter-based export
Upload a full manuscript, get back individually-named chapter files instead of one giant one to split manually.
Pronunciation overrides
Lock in the correct pronunciation for character names or jargon once — applies everywhere it recurs.
Consistent across sessions
Chapter 12, generated a week after chapter 1, sounds like it was recorded in the same sitting.
Upload your manuscript
A text or Word file with clear chapter markers.
Set pronunciation overrides
For character names and unusual terms, before your first full generation pass.
Generate the full manuscript
Chapters process in parallel, so a 40-chapter book doesn’t take 40× as long as one chapter.
Why long-form narration is a different problem than a short clip
Generate a two-sentence voiceover twice and any tiny variation is invisible. Generate 40 chapters across several sessions and that same variation compounds — a listener jumping from chapter 3 to chapter 30 can notice a shift in pacing or tone. Long-form mode locks a single voice "seed" and pacing profile for the entire manuscript, so every chapter generates against the same baseline.
Rights and licensing
If narrating your own voice, you retain full rights. If using a licensed library voice, commercial audiobook and podcast distribution is included on Pro and Studio plans.
- What happens if I need to fix one paragraph after the whole book is done?
- Regenerate just that chapter — the locked voice seed means it will match the rest of the book.
- Can different chapters use different narrators, like a multi-cast audiobook?
- Yes — assign a different cloned or library voice per chapter or character line, each with its own locked consistency profile.
