Text to speech that works completely offline
The voice lives on your device, not a server
Most text-to-speech apps need a live connection to generate
natural-sounding audio. PhonoLeaf's voice runs entirely on your device.
Save a book for offline listening, and it keeps reading with no
connection at all.

Offline isn't a fallback mode
The voice runs on your device
PhonoLeaf's natural voice is generated locally. No audio is streamed from a server, ever, online or off.
Save a book for offline
Download a book once, and read it anywhere: on a flight, underground, or anywhere with no signal.
Nothing uploaded
Your book's text never leaves your device to be processed. That's true whether you're online or not.
Keeps reading, screen off
Playback continues when your phone is locked, with lock-screen play/pause and chapter controls.
