Sovereign: Private AI Notes

Sovereign is a personal assistant that keeps your life on your phone.

Notes, tasks, journal entries, passwords, secrets and API keys live in one encrypted vault on the device. The AI that reads them runs there too. No prompt leaves your iPhone, no server sees your content, and there is no account to create before you can start writing.

What you can keep in it

Write notes as plain text, checklists or markdown. Capture a task by typing it, speaking it, or letting the app pull it out of something you already wrote. Keep a daily journal with a mood and a photo. Store passwords, API keys, recovery secrets and social logins in fields shaped for each kind, so a password looks like a password and an API key keeps its environment.

An assistant that stays on the device

A language model on your iPhone writes your daily briefing, suggests what a note means for your week, turns a rambling voice memo into a journal entry, and answers questions about what you have written. Ask it anything about your own vault and the answer is worked out locally.

Growth, with evidence

Name something you want to get better at. Sovereign watches what you capture and links the notes, tasks and entries that actually served it, so progress is something you can read back rather than something you log by hand. Add habits under a skill, give each one a cadence, and tick them off as you go.

Birthdays

Add the people you keep meaning to remember. A reminder arrives the day before and again on the morning, with the name, the age and the photo.

Encryption you do not have to trust us about

Every record is sealed on the device with a key held in the Secure Enclave. Turn on iCloud sync and only ciphertext crosses the wire, so Apple stores bytes that only your key opens. Lock the app behind Face ID. Export everything at any time. Delete everything at any time, including the key.

What it does not do

No analytics. No advertising identifiers. No tracking pixels. Nothing is sold, because there is nothing readable to sell.

Pro

Inbox triage, reflective conversations, your skill coach and asking questions of your own notes are part of Pro. Everything else, including the vault, the journal and the encryption, works without paying.
