SOVEREIGN / The world’s smartest journal
Write on paper or in the app. Tertius, the intelligence in Sovereign, helps you discover your patterns, put your experiences in context, and make room for what matters.
Discover Sovereign
More than a record of your day
A full calendar can be a good week. Or a hard one. Your words tell the difference. Sovereign brings your journal, your plans and your circumstances together, so there’s more to go on than a list of events.
Your journal / In your own words
A good afternoon. A difficult conversation. The thing you can’t stop thinking about. Keep the details you want to remember, in the app or on paper.
“Loved seeing everyone. Spent most of it in the kitchen. I’m exhausted.”
Your journal keeps the story. Tertius helps you look back, notice what keeps coming up, and think through what you want to do differently.

Your Desk / With Tertius
The moving truck. The appointment you keep putting off. Something you want to get back to. Drop it all on the Desk. Tertius sorts it into intentions, goals and plans, and helps you work out what comes next.
Reserve the moving truck.
Set up electricity.
Need a dentist appointment.
I want to run twice a week again.

A routine to get back to
You have 30 minutes free tomorrow before your appointment. Use it to reserve the truck and set up electricity?

Built around you / Contexts™
Starting something new and getting back on your feet ask different things of you. The same rhythm won’t help in both seasons. Discover the patterns that change with your pace.

“I used to know what I wanted.
Now I’m not so sure.”
Before another goal, some space to work out what matters to you now.
Contexts™ brings six parts of your life into view: how you think, connect, recover and respond to pressure, the season you’re in, and where you want to grow. You can revisit your context as your circumstances change.
Illustrative situations, drawn from the Contexts framework.
Sovereign / With you, every day
A plan for moving day. Time for a run. Dinner with friends that you actually get to enjoy. Sovereign helps you make room for the things you wrote about.
And when life changes, your journal, your context and your plans change with you.

No. An entry can simply be an entry. Drop ideas, goals and to-dos on the Desk whenever you need to. Tertius keeps them organized and helps you decide what to do next.
Tertius is the intelligence in Sovereign. It helps you talk through what you’ve written, connect it with your goals and what’s happening in your life, and decide what to do next. On the Desk, that can become suggested steps and time in your calendar.
Your current circumstances matter. Building something new and recovering from a difficult period call for different support. Contexts™ gives Sovereign a starting point for understanding how you think, what helps you recharge and what you need now. You can revisit it as life changes.
Your writing belongs to you. Our Safe Harbor Pact sets out our commitments on data ownership, security, export, deletion and the use of your information.
Reclaim your rhythm.
