Kuyun. Frontier AI for everyone.

The newest AI technology shouldn't require blind faith. Kuyun (say “koo-yoon”) is reliable, transparent, and accountable by design: it explains every answer, keeps an inspectable record of what it did and why, and is shaped by you — not the other way around.

Four things no generic assistant does

Remembers you

Tell it once. Preferences, projects, and context carry across every conversation — and keep getting better.

Shaped by you

Say “be more direct” or “always answer in Spanish” — Kuyun adapts, permanently. Your assistant ends up fitting exactly you.

Knows itself

Ask how its memory works and it answers by reading its own source code — not from marketing. Every answer has a “why?” you can open.

Grows with you

Your feedback shapes how it behaves — and you can even propose new abilities in chat. Real requests have shipped real features.

Your data, plainly

Everything Kuyun learns about you is visible and editable on your “What Kuyun knows” page. Corrections are honored immediately. And there is a real delete-everything button: it removes your conversations, memories, and account completely — not a hide, a delete. Don't take our word for any of this — ask Kuyun itself how it stores and forgets; it will read its own code to answer.
