What Luna is

A calm, local AI companion built for everyday presence — not a cloud chatbot.
Runs on your device with local models, so chats stay on your machine by design.
VRM avatar presence with voice via Edge TTS for a fuller companion experience.
Long-term memory so conversations can feel continuous over time.
Optional cloud models when you want them — local-first remains the default path.
Built with privacy, clear boundaries, and long-term reliability in mind.
