Apps that thinkon your phone.
We make reading and voice apps whose AI runs entirely on iPhone. No servers, no accounts, nothing uploaded.
On-device
No cloud. The whole model is in here.
Every voice our apps speak is generated on the chip in your hand, one sentence at a time while you listen. Switch on airplane mode and nothing changes.

Three apps. One idea.
Each one turns words into a voice you would want to listen to for hours, and each one does it without a server.

How we build.
On-device, first.
If a feature needs a server, we redesign the feature. Your books, scripts and voices stay on your phone, which also means they work on a plane, in a tunnel, or at 2 a.m. with no signal.
Measured, not guessed.
Every model is benchmarked on real iPhones before it ships: speed, memory, heat and battery. If it runs too hot or too slow, it does not ship.
Made for people.
No jargon, no settings maze, no dark patterns. A free version that is genuinely useful, and upgrades you pay for once.
