 **Image Understanding (Multimodal)**: Take a photo or pick one from your library, then ask questions directly. Identify objects, read charts, describe scenes — all inference happens on your device, and your photos never leave your phone.
 
-**Calendar / Reminders / Contacts**: Create calendar events, set reminders that fire on time with a push notification, and save or update contacts — all through natural language. Every write operation stays local. Contacts are automatically deduped by phone number.

-**Clipboard & Device Info**: Read and write the system clipboard, query device name, OS version, and available memory. Useful as a data relay in multi-step tasks.

 **File-Driven Skill System**: Each capability is defined by a single Markdown file (SKILL.md). Adding or modifying a skill requires no recompilation. Skills are language-agnostic — anyone can write and share them.
 
 **100% Offline & Private**: All inference runs on the local GPU. No network connections are made by default. Your conversations, images, and personal data are never uploaded or routed through any third-party server.
 
 **Flexible Model Management**: Supports Gemma 4 E2B and E4B. Download models directly on your iPhone, or bundle them into the app at build time. Includes a built-in model switcher, system prompt editor, and automatic history trimming for iPhone memory constraints.
