Common questions
How does Warblize create an audiobook?
Upload your EPUB, PDF, DOCX or TXT. Warblize extracts the text, structures chapters, and narrates every sentence with a studio-grade voice. You get files ready for Spotify, Apple Books and other distributors.
What files can I upload?
You can upload an EPUB, PDF, TXT and DOCX files up to 100 MB.
Can I fix a line without regenerating the whole book?
Yes. The studio breaks each chapter into sentences. Edit one sentence and regenerate just that line. Everything else keeps the audio it already has.
Can different characters have different voices?
Yes. Each book has its own cast. Add a character, give it a voice, and assign any sentence to it, so dialogue is actually performed by more than one narrator.
How many languages and voices?
47 languages and 30 humanlike voices with local accents and distinct delivery styles. If the narration language differs from your manuscript, Warblize translates as it narrates.
Do I own the commercial rights?
Yes. Every audiobook you generate includes full commercial rights. Publish on Spotify, Apple Books, Kobo and Google Play, or sell directly. Check the stores’ own rules for AI narration before you upload.
How does pricing work?
Choose a subscription or pay on-time to purchase credits. One credit covers 60 minutes of finished audio, and credits stay valid for 12 months.
How long does it take?
Most books generate in 5–15 minutes. A 60,000-word novel typically takes about 8 minutes.
