Senian

The AI assistant that never phones home — now with private iCloud sync across your devices and a more powerful optional model. No subscription, no cloud, no catch.

Senian is a private AI assistant that runs entirely on your iPhone and iPad — no cloud, no subscription, no data sent anywhere.

Ask questions, get help writing, think through problems, or just have a conversation. Everything happens on your device using Google's Gemma AI model.

PRIVATE BY DESIGN Your conversations never leave your device. There are no accounts, no servers, and no data collection. What you say stays with you.

NO SUBSCRIPTION One purchase. Use it forever. No monthly fees, no ads.

WORKS OFFLINE Once the AI model is downloaded, Senian works without an internet connection. Optionally enable web search for current information.

ICLOUD SYNC Enable iCloud Sync to keep your chat history and settings in sync across your Apple devices, through your own private iCloud account.

ABOUT THE AI MODEL Senian uses Gemma 3 1B by Google, a compact model optimized for on-device use. The model (~800 MB) downloads once on first launch. A working internet connection is required for that initial download only.

Senian is an AI assistant and can make mistakes. Its responses are not a substitute for professional medical, legal, or financial advice.

Note: Senian runs best on iPhone 12 Pro / iPhone 13 or newer. Older iPhones with less memory will work but may run slower.
