Zerobar AI
Private offline assistant
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
No account, no cloud, no connection. Ask it anything on a plane, on the metro, or with your data switched off — the model runs on your iPhone and nothing ever leaves it.
Zerobar AI is an assistant that runs entirely on your iPhone. No account, no server, no connection — not even a hidden one. Put the phone in Airplane Mode and everything still works.
REQUIRES APPLE INTELLIGENCE
The assistant needs Apple Intelligence, which means iPhone 15 Pro or newer and iOS 26.2 or later, with Apple Intelligence switched on in Settings. On other iPhones the app still gives you the calculator, the calendar and reminder forms, text recognition from photos and your notes — but not the chat.
ASK IT EVERYDAY THINGS
How do I get red wine out of a shirt. What can I cook with eggs, rice and an onion. Explain what a mortgage rate is. The model answers from its own knowledge, so none of it depends on a signal.
WORK WITH YOUR OWN TEXT
Paste, dictate or photograph text and the app will summarise it, rewrite it in a different tone, fix the grammar, or pull out the names, dates and amounts. Photos are read on device — the picture never leaves your iPhone.
REAL TOOLS, NOT GUESSES
Language models are bad at arithmetic and have no idea what today's date is. Zerobar AI doesn't guess: it runs a real calculator, reads the real date, and reads your real calendar. Ask it to remind you of something and it prepares the entry — then shows you exactly what it is about to save. Nothing is written until you tap to confirm, and the assistant can never delete anything.
PRIVATE BECAUSE IT CANNOT BE OTHERWISE
This isn't a promise about how we handle your data. The app makes no network requests at all, so there is nothing to handle. No analytics, no tracking, no third-party AI provider.
HONEST ABOUT ITS LIMITS
The model is small enough to fit on a phone, which means it can be wrong. It has no way to check anything live — weather, prices, news, sport — and will tell you so rather than invent an answer. Conversations are short by design: the on-device context window is limited, and the app shows you how full it is.
