Castory
What it is
Castory is a web service that converts manuscripts into chapter-organized audiobooks for authors and publishers. It supports fiction, nonfiction, and serialized projects, with multiple narration roles for dialogue and characters. Castory says its library contains more than 50 voices for multilingual audiobook creation, and its AI examines genre and emotional tone to suggest narrators for chapters and characters. Users can upload PDFs and more than 10 other document formats; the homepage says one workflow can process novels up to 100,000 characters. Before generation, narration settings can be previewed and adjusted, then audio files can be exported for distribution. An EPUB workflow supports online listening and downloading chapter audio as MP3 files. Users retain ownership of uploaded content, and Castory says it does not claim ownership of generated audio. Uploaded material is not used to train general-purpose AI models without explicit consent. Files and results are stored only as needed and can be deleted through the interface. A free plan is listed as free.
