The concept

Seventy-eight cards, each one a small piece of meaning

Tarot is a reading practice built on a deck of seventy-eight cards, each with its own symbolism, used to think through a question from a different angle. The Rider-Waite deck is the canonical one. Tarot CoPilot encodes that whole system so a reading feels personal and considered rather than random, a real conversation with a very old interface.

Why it is here

Proof I build with the new medium, not just talk about it

I have always had a split brain, technical and artistic. Tarot CoPilot is that split made concrete: a hands-on build with the current medium, the same instinct that runs from a photo studio to a data platform to an AI agent. New tools, same person on the other end.

The medium keeps changing. This is me keeping my hands in it.
