Local AI narration
Use downloadable neural voice options powered on the device, with availability determined by the selected model and book language.
Download a compatible AI voice once, then let EpubTidy narrate your DRM-free EPUB directly on the iPhone. Keep listening on flights, underground commutes, quiet trails, and anywhere a connection is unavailable.
After a voice model is downloaded, EpubTidy processes the book locally. Your EPUB does not need to be uploaded passage by passage to a remote text-to-speech service during playback.
