Features
Every character, in their own voice.
Full-cast audiobooks — the ones that used to cost a studio and a budget — running on hardware you already own.
A full cast.
One narrator can't be everyone. The apprentice sounds thirteen; the swordsmith sounds seventy and a forge. Castwright reads your manuscript, detects every speaking character automatically, and assigns each a distinct voice — no manual tagging required.
Dozens of voice designs ship out of the box, and every cast member's voice can be swapped, refined, or replaced in seconds before generation begins.
Series-consistent.
Book two should sound like book one. Castwright remembers your cast — even when an author renames someone mid-series. The cross-book voice library links characters by identity, not just name, so a returning favourite carries the same voice across every instalment.
Open a sequel and Castwright will surface every prior voice assignment, flag newcomers, and let you approve the full cast in one screen before a single syllable is rendered.
Your own voice. In development
Read a bedtime story in your own voice, even when you're away — or let your kid be the hero. Voice cloning is in development for the next release: your voices, with your permission, will stay on your machine — nothing uploaded, the cloning model running locally alongside the synthesis engine.
Family voices, character personas, and custom designs will live in your private library and travel with your books — not with a vendor's server.
Yours to keep.
Rendered once, on hardware you own. No meter, no monthly fee, no server that can take your library away. Every chapter is written to disk as a standard audio file the moment it finishes — export to MP3, share a clip, or sideload to any player you like.
Castwright is free — and if it shut down tomorrow, your audiobooks wouldn't disappear.
On every screen in the house.
Castwright runs on your own machine — and its screen goes wherever you are. Open it from the sofa on a tablet, or from the kitchen on a phone: same library, same cast, same place in the book, over your own Wi-Fi.
No cloud in the middle — your own network is the only wire. For listening away from home, that's what the companion app is for.
Your book, out the door.
The companion app pairs your phone to Castwright with one QR code. Your library — covers, chapters, the lot — syncs over your own Wi-Fi; nothing touches a cloud.
Download a book and it plays offline: chapter marks, playback speed, auto-advance, and your listening place kept in sync — pause at the kitchen table, resume on the train. iOS and Android, shipping at launch as part of the Cast Pass.
