No credit card · Private by design · Yours to shape
Why Kōzō exists
Most people don't lack ideas. They lack a place where those ideas can live, grow, connect, and become something real. Kōzō is that place — calm, private, and shaped by you.
AI helps you think, never replaces it. You stay the author.
Your thoughts, journals and ideas are yours. Encryption is a principle, not a feature.
Turn features on, off, or rebuild them. Your brain isn't a template.
What's inside
Magic-plus button captures any thought in 2 seconds — keyboard, mouse or voice. Your stream becomes structured tasks and notes automatically.
Markdown + LaTeX, blocks, wikilinks, file embeds and a graph view. A note can become a meeting log, a research page, or the heart of a project.
Today, Upcoming, Someday, Eisenhower matrix, kanban — pick the lens that fits. Drag to reschedule, tag to triage.
Drag tasks onto a calendar. Subscribe to .ics feeds, sync birthdays from your contacts, and keep your day in one calm pane.
People, places, projects, books, ideas. Each becomes a page that gathers everything related — past and future — automatically.
Pomodoro, ambient sound, distraction-free mode. Quiet the stack and do the work that matters.
Spaced-repetition (FSRS) built in. Turn any note into a deck. Daily reviews that actually stick.
Shared spaces, organisations, custom roles. Invite teammates without losing the calm.
Sketch ideas as mindmaps, plan with kanban, draw flowcharts — without leaving your note.
