AI

  • Zeno

    My AI agent. He makes phone calls, handles my email and plans my week, and anything that matters waits for my Face ID.

    Making real phone calls since 12 Nov

  • Zeno Desk

    My old iPhone as Zeno's desk screen. It reads my hand gestures, and a box I built decides when it charges.
