About FullCastBook
FullCastBook turns a manuscript into an AI audiobook with a full cast. Upload an EPUB, PDF, DOCX, TXT or Markdown file, or paste a chapter, and it finds the chapters, works out who is speaking in each line and gives every character a distinct voice alongside an AI narrator. Swap any voice from a library of standard and premium voices, regenerate a single line without redoing the chapter, and export one M4B with chapter markers, MP3 files or a ZIP. Freemium: paid plans from $9.90 a month, no free credits. English works best today; scanned page images are not supported.
