Ninput: Private AI Keyboard

Type less, say more. Ninput helps you write in English or Chinese Pinyin with word, phrase, and sentence suggestions processed on your device.

IPHONE DUO
A keyboard that adapts to your space, with responsive layouts for the iPhone Duo outer and inner display.

PRIVATE BY DESIGN
Your typing, predictions, and learned language data stay on this device. Ninput does not upload what you type. You can use the keyboard without enabling Full Access.

ENGLISH & CHINESE PINYIN
Switch between English typing and Chinese Pinyin from the keyboard. The active input language is clearly shown.

ON-DEVICE AI
On compatible devices with Apple Intelligence enabled, Ninput uses Apple's on-device model for context-aware suggestions. Once the model is ready, AI suggestions work offline. Initial model download may need an internet connection. Availability varies by device, language, and region. Requires iOS 26 or later.

OFFLINE INPUT
Basic typing, Pinyin conversion, and local dictionary suggestions work offline without Apple Intelligence.

FREE TO TRY
Explore smart input with a daily allowance. After it runs out, regular typing and basic suggestions remain available. The allowance resets each day.
