Sirina: Offline AI Chat

Sirina is a privacy-first, offline AI chat assistant for iPhone, powered by Apple Intelligence on supported devices.

Built for privacy, core AI chat runs on-device, so your prompts and responses are processed locally instead of being sent to external AI servers.

If you want multi-device access, you can optionally enable iCloud sync to keep conversations in sync across your Apple devices using your private iCloud account.

Simple, fast, and built for people who want AI help with a privacy-first, offline-first design.
