Sovereign: Private AI Notes

New: everything runs on Apple's on-device model. No download, no account, no upload. Your notes never leave your iPhone.

Notes, journal, and tasks that stay on your iPhone.

Sovereign encrypts everything you write with AES-256 before it touches storage, using a key held in your iPhone's keychain. The AI runs on Apple's on-device model. Nothing is uploaded, nothing is trained on, and there is no account to create before you start writing.

WRITE WITHOUT THINKING ABOUT IT Type it, dictate it, or share it in from Safari, Mail, or anywhere else. Sovereign titles it, files it, and pulls out anything you said you would do.

AI THAT RUNS ON YOUR PHONE Titles, action items, daily briefings, and journal entries are generated by Apple Intelligence on the device itself. There is no model to download and nothing to wait for. On iPhones without Apple Intelligence the app still works; it uses built-in text analysis instead.

A JOURNAL YOU WILL ACTUALLY KEEP Talk for two minutes about your day. Sovereign turns the ramble into a written entry in your own voice and lifts out the tasks and events you mentioned.

TASKS THAT COME FROM YOUR NOTES Due dates, priorities, and overdue flags. Add them yourself or let Sovereign find them in what you already wrote.

FIND IT LATER Search reads the whole note, not just the title. Your notes can also appear in Spotlight, and you can turn that off in one tap.

EVERYWHERE YOU ARE Home Screen and Lock Screen widgets, a share extension for capturing from any app, and Siri and Shortcuts support so you can say "capture a note in Sovereign" without unlocking anything.

LOCKED IF YOU WANT IT Turn on Face ID and the vault stays sealed until you unlock it. Leave it off and the app opens straight into your notes.
