ChatAI - On Device AI

Chat with an AI that runs entirely on your iPhone. No account, no internet, nothing leaving your device — now with voice input, personas and Face ID lock.

ChatAI lets you have intelligent conversations powered entirely by Local On-Device Intelligence — running directly on your device.

• Completely Private: Your conversations never leave your device. No servers, no tracking, no accounts required.
• Chat History: All conversations are saved locally. Rename, organise, and revisit past chats anytime.
• Fast & Offline: Works without an internet connection since everything runs on-device.
• No Subscriptions: No hidden fees. Uses Local On-Device Intelligence built into your iPhone.
