Ceiling

A working library of AI product interface patterns.

Pattern-first teardowns of how AI products actually feel. Not principles. Not personas. Patterns composers, streaming, thinking indicators, plan previews, tool calls. Anonymized and published free.

Thesis
  1. Interfaces are how AI gets honest.

    A model can be right and still feel wrong. A model can be wrong and still feel trustworthy. The interface is the part that decides.

  2. Patterns outlive principles.

    I don't need another list of values. I need a reference shelf of specific moves, with the conditions they work in and the failure modes they invite.

  3. A teardown is an argument, not a verdict.

    Every pattern here is broken down the same way what it does, how it fails, who it serves. The writeup isn't the point. The debate it starts is.
