Oratio Coming soon to iPhone
On-device narration for iPhone
Oratio turns EPUB books into natural narration on your iPhone. No uploads. No signal needed once your voice is downloaded.
Welcome to Oratio. The voice you’re hearing now already lives on your phone — no download, no setup, no subscription.
Every book you bring here can speak from the very first second. But this is only where we begin.
01Private by design
Most AI voices start by sending your words to a server. Oratio’s speech models run on your iPhone, so the page never leaves your hands.
02Three ways to read
Follow along, focus on one passage, or let the words come to you one at a time. The voice keeps going through all three.
In my younger and more vulnerable years my father gave me some advice that I’ve been turning over in my mind ever since.
“Whenever you feel like criticizing anyone,” he told me, “just remember that all the people in this world haven’t had the advantages that you’ve had.”
He didn’t say any more, but we’ve always been unusually communicative in a reserved way, and I understood that he meant a great deal more than that.
Every word lights up as the voice reaches it.

One passage at a time. The rest of the page steps back.

One word at a time, from 240 to 420 words per minute.
03The narrators
Each narrator has a warmth, a pace and a point of view. Download one once, and it reads to you anywhere.
The Fireside Narrator
Pocket TTS · runs on device
“A life sounds different when told beside a fire, where even small moments grow into stories.”
Each narrator is a fictional persona. Samples play only when you ask.
04Made for iPhone Duo
Closed, Oratio is a focused single column. Open, the library spreads across the wider screen.
05Discover
Browse curated shelves of public-domain books from Project Gutenberg. One tap downloads the book straight to your phone.
06The fine print
No. Speech generation happens on the device, so a book does not need to be uploaded to a third-party voice service.
Reading and on-device narration work offline after the book and voice model are on your phone. Browsing the catalog and downloading books or models still need a connection.
EPUB. Oratio reads the EPUB files you import and the free books in its catalog.
Oratio’s catalog indexes public-domain books from Project Gutenberg. Book files are downloaded directly from Gutenberg.
Oratio supports Apple’s built-in speech and downloadable on-device voice experiences powered by models such as Kokoro, Pocket TTS, and Supertonic.
Soon. Oratio is not out yet. It is coming to the App Store for iPhone, and this page will link to it when it is available.
This is Oratio. Bring your own books. Choose your voice. Read however you like — aloud, focused, or fast. Whenever you’re ready, let’s begin.
