Human vision. AI execution. Real products.

We don't use AI to write code faster.
We use AI to build what one person couldn't build alone.

The best tools come from understanding a problem, then solving it with whatever works best — today that means human judgment paired with AI capability.

• Human → vision, taste, the decisions that matter
• AI → execution, iteration, everything that scales
• Together → products one person couldn't ship alone

This isn't about replacing developers. It's about what one developer can build now.

Each name is a Japanese word; the meaning is the function, and the subject is always a human act — read, watch, keep. All MIT, local-first, privacy-first.

_{AII — the manifesto layer (interfaces should understand people, not the reverse).  ·  cortex — an early forerunner, now archived.}

The code is the proof. Not slides. Not demos. Not Twitter threads. Clone it. Read it. Run it. Break it.

Everyone ships with AI now; the only question is whether yours can be cloned, read, and verified. If AI-native development works, you should be able to see it in the commits.
