Captions, and a transcript that owns its mistakes: what's new in v1.12

July 10, 2026

v1.12 is a release about honesty and permanence: captions you can keep and share, and a transcript that’s more forthcoming about what it knows — and what it got wrong.

Captions, from any finished book. Export captions alongside the audio — SRT or VTT, at line, sentence, or word level, for the whole book or a single chapter. Line and sentence captions are read straight from your book’s own alignment, so there’s nothing to re-record; word-level timing calls on the local Whisper model for the fine grain a demo clip wants. Drop a chapter into a video and the words track the voice, or read along on the page while you listen.

A transcript that owns its mistakes. As Castwright reads your book and works out who’s speaking each line, it now checks its own answers against the evidence in the text — the dialogue tags, the back-and-forth of a scene — and corrects the ones the text proves wrong, before you ever see them. And where it used to report a breezy, inflated confidence in every call, it now reports one it can stand behind. So the lines it’s genuinely unsure about actually surface for a second look, instead of hiding behind a number that was never earned. In English, Russian, Spanish, French, and German.

Script-review notes that survive a reload. The notes from a script review used to live only in the moment — reload the page or close the tab and they were gone, whether you’d acted on them or not. They now persist: a review picks up where it left off, and closing the results can never quietly discard them. Only an explicit “Dismiss all” clears the slate.

A voice design that recovers itself. Designing a voice with the Qwen engine could occasionally fail with a blank error, and then keep failing until you restarted the app. Now the engine notices the fault and recycles itself, so the next attempt starts on a clean slate — the failed one still tells you plainly it didn’t work.

And getting all of this onto your machine got easier, too: the one-click Pinokio install now runs the whole way through.

Many voices, one machine.
