Private alpha Waiting list

ZENREI-lang. A language invented for AI.

AI that builds software. From Japan.

Zen meets AI.
Software for your most complex work, built not to break.

Tell ZENREI what you need. Its AI builds software for you alone, with everything you need and nothing you don't. Keep adding to it for years, and it stays whole.

Collect Saturday attendance for me. Build
Be among the first Because it doesn't break, it can grow.

How it feels

You say it. The AI builds it.
Nothing is lost.

The idea

Zen does not remove complexity.
It brings it into harmony.

  • Every stone keeps its shape.

    In a Zen garden no stone is cut to match another. What you feel there is harmony, and none of it comes from removing things.

  • Your work keeps its shape.

    Exceptions, special cases, rules only you understand. Most software asks you to cut them away. ZENREI keeps them.

  • Each part agrees with the whole.

    We invented a language for AI that checks every part against all the others. That is why it does not break as it grows.

Under the surface

Quiet above. Deep below.

You see one switch. Beneath it, every rule of your work is checked against every other, each time anything changes.

ZENREI :: 禅麗 t => t

Why it doesn't break

ZENREI is written 禅麗. Zen, and grace.

The weekly tangle, undone.

  • Soccer clubBefore: Counting replies in the group chat

    After: Attendance is in by Friday night

  • Baseball teamBefore: The phone tree on a rainy morning

    After: One tap reaches everyone

  • Piano studioBefore: Rewriting the planner for every makeup

    After: Parents pick an open slot

  • NeighborhoodBefore: "Wait, whose turn is it?"

    After: The app remembers

  • Salon, clinicBefore: Taking every booking by phone

    After: Clients book themselves
  • Friday night is yours again.
  • No more "nobody told me."
  • Your hands return to the real work.

The thinking behind it

Complex inside. Quiet to use.

Three ideas from Zen aesthetics shape how it feels in your hands.

  • 不均斉Fukinsei · asymmetry

    No two parts alike. Every rule of your work keeps its own shape.

  • 自然Shizen · naturalness

    Nothing forced. Your work is taken as it really is, exceptions and all.

  • 静寂Seijaku · stillness

    However much runs underneath, the surface stays calm.

円相The ensō is a circle drawn in one breath and left open. Never finished, always whole. A ZENREI app is meant to live the same way: you keep adding to it, and it stays whole.

How it differs.

Like tree rings

It starts small.
It grows as far as you do.

Start with attendance. Grow it into fees, schedules, records, the whole operation. Every new ring leaves the inner ones intact.

How to become a first creator

Can I use ZENREI right now?

Not yet. ZENREI is in Private Alpha, before general availability. You can join the waiting list, and we will tell you when it is ready for you.

Do I need to know how to program?

No. What you need is a deep understanding of your own work.

Will my know-how be shared with others?

Not without your say. Wider sharing requires your explicit consent.

How do I become a first creator?

Write to us and tell us how you run things today. We reply to each person individually.
