Coming in 1.3.0 for Windows

Windows 1.3.0 is pending Microsoft Store approval. Document narration and the new import flow will arrive with that update. Check each store for the version available on your device.
Turn Word (DOCX), text PDF, EPUB and TXT files into M4B or MP3 audiobooks. Review chapters, preview a voice, and adjust narration speed and pauses before generating on your PC.
Already in 1.2.0: convert formats, merge MP3 tracks into a chaptered M4B, export chapters or sections, create smaller copies, and edit titles and covers. Originals stay untouched.
Open supported audio files with LibroNest from File Explorer. Review the import, keep a copy, replace a matching track, or start playing a book already in your library.
Narration needs a one-time engine and voice download, then works offline. Keep LibroNest open while generating. Use readable, unprotected documents; scanned PDFs need text recognition elsewhere first. Windows ARM narration requires Windows 11 for x64 runtime support.
