The product
What Castwright is building
Castwright is a desktop-oriented audiobook production tool that turns books into voiced, full-cast listening experiences. Its June launch post describes the public beta as available for free download, with installers and a Cast Pass available at launch. The product focuses on local use, configurable character voices, and an output workflow that can send completed books to a personal audiobook library.
