Private AI,
in your pocket.
Apple Intelligence runs entirely on your iPhone through Apple's Foundation Models framework. Your messages never leave the device. No network traffic, no tracking, no account required.
Apple Intelligence, first.
Chat with Apple Intelligence running entirely on your device. Your messages never leave your iPhone. No account, no subscription, no telemetry.
On-device by default
The default chat mode uses Apple Intelligence through the FoundationModels framework. Responses are generated locally on your iPhone, with zero network traffic.
iCloud sync across your devices
When you Sign in with Apple, your chats sync automatically across your iPhone, iPad, and Mac through iCloud Key-Value Store. Your data stays in Apple's encrypted cloud, never on a developer server.
Two ways to start
Sign in with Apple for private on-device chats synced through iCloud, or start anonymously in a single tap. No phone number, no email, no sign-up form.
iOS 26 Liquid Glass
Built entirely in SwiftUI using Apple's new Liquid Glass design language. Glass buttons, ambient backdrops, frosted sheets, and smooth, playful motion.
Zero collection, zero ads
No analytics, no trackers, no ads, and no data collected by the developer. Authentication tokens stay in the iOS Keychain on your device.
Apache 2.0 open source
Free, non-commercial, and fully open-source. Fork it, audit it, extend it — the client is built from public code, by design.
Built to be trusted.
Ultra Open Client is a free, non-commercial iOS app for private chat with Apple Intelligence. It has no third-party UI dependencies, no analytics SDKs, and no hidden network calls. The code is open for anyone to read.
