Senian is an AI assistant that runs entirely on your iPhone or iPad. Ask questions, get help writing, or think through problems — all on-device. No cloud, no accounts, no data collection. One purchase, no subscription.
Most AI apps send everything you type to a server. Senian doesn't. The AI model lives on your iPhone, so your conversations stay with you.
Your conversations never leave your iPhone. No accounts, no servers, no data collection — there's nothing to leak.
Pay once and use it. No monthly fees, no upsells, no ads.
Once the AI model is downloaded, Senian works anywhere — on a plane, in the subway, off the grid.
Ask questions, draft messages and emails, summarise, brainstorm, or talk through a decision.
Turn on web search for up-to-date answers. It's off by default, and you're always in control.
Optionally sync your chats and settings through your own private iCloud account.
How private is it? Senian processes everything on your device using Google's Gemma AI model. Your prompts and responses are never sent to Senian's servers. The only time anything leaves your phone is if you turn on optional web search, which sends just your search query to a search provider.
Only once — to download the AI model (~1.1 GB) on first launch. After that, Senian works fully offline. Optional web search needs a connection when you use it.
Yes. The AI runs on your device. Your conversations are not collected, transmitted, or stored on any Senian server. See our privacy policy for the details.
No. Senian is a one-time purchase with no recurring fees and no ads.
Senian runs a compact on-device model. It's fast and private, but less powerful than large cloud AIs and can sometimes be wrong. It is not a substitute for professional medical, legal, or financial advice.
iPhone and iPad running iOS or iPadOS 17.6 or later, and Apple Silicon Macs. Newer devices run the model faster; older devices may take longer to download and respond.
