How cloud AI works
What cloud AI can and cannot do.
- Off until you turn it on
- Luna runs on OpenAI's servers. It stays off until you accept the Cloud AI terms, and you choose which notes each request may read. A sensitive note goes only after a warning.
- On-device AI costs nothing
- Local models run on your own iPhone, iPad or Mac, on any plan, and never spend a credit.
- You approve every change
- The AI can propose a new note or an edit. Nemosine waits for your approval before it saves anything.
