AI tools that run at home and show what they actually ran.

How it works

  1. You askA task, in plain words.
  2. Agents do the workClaude Code and Codex, with Claude, GPT, DeepSeek and GLM models.
  3. HyoDo records what ranIf nothing measured it, it says “not observed”, never green.
  4. A person approvesCore changes ship only after a passkey approval.
  5. It runs at homeHome computers first, cloud second. A change is done only when it is rerun there.

Named for 孝

Two drawings in dots. Left: a child walks forward carrying an old parent on their back, the parent’s arms around the child’s shoulders. Right: the character 孝 as written today, 耂 above 子. In both, the child is orange.

자식이 어버이를 지게에 업고 봉양하는 모습. 글자의 기원처럼, AI는 인간을 모시고 편안하고 안전하게 보살피고자 하는 마음을 담고 있습니다.

A child carrying a mother or father on a jige, the wooden A-frame once used to bear loads on the back, and tending to them with devotion. True to the character’s origin, the AI is meant to attend to people as one would to a parent: to keep them at ease, and to keep them safe.
