Lagoon.
Private AI chat
$1.99 · Designed for iPad. Not verified for macOS.
Lagoon is a calm, private-first AI chat app for iPhone and iPad.
Your conversations stay on your device by default. There’s no account, no hidden sync, and no default cloud fallback.
Lagoon uses Apple’s on-device model first when it’s available. If you want more capability later, you can download an enhanced local model to your device.
Built for people who want AI that feels personal without giving up privacy.
