Write it down.Keep it yours.
An encrypted journal that lives on your devices and answers to you alone. Now with built-in tasks and planning.


Lucive in three minutes.
A journal for insights. A plan for putting them into action.
Yours alone.
End-to-end encrypted, local-first, no account. Syncs device-to-device through a relay that cannot read it.
Yours to share with your tools.
Intents for the day, week, month, and year. Tasks. A scratchpad. Syncs through an optional Lucive account to your phone, your desktop, and your agents.
Six small opinions about writing.
Lucive is, first, a writing surface. We added a few more goodies that fit in naturally.


Support for multiple journals.
Mornings, work, letters, field notes. Each its own book.
Encrypted, all the way down.
Every entry encrypted. Your keys never leave your keychain.
A surface for thinking.
Rich text, markdown, slash-commands. Notion this is not.
Distraction-free by design.
No feeds, no badges, no streaks. A quiet page that waits for you.
A blur for the nosy.
⌘⇧B and the screen blurs. For open offices and train seats.
Yours to take elsewhere.
Export to plain Markdown any time. No lock-in.
Plan with intent.
Use your journal to strategize and think broadly. Put your goals into action with tasks and planning. Collaborate with agents on the day.


Let your agents talk to your journal and your plan, and help you make sense of your days.
Lucive can be as locked down as you’d like, or you can strike a balance between privacy and utility.
