About codebrew
We didn't animate it. We ran it.
codebrew shows how things actually work, and runs them in front of you. It's built for people who want to understand, not memorize.
The standard
Rule 1
No visual without a model behind it
Every state you see on a stage was produced by executing code: a simulator, or real code being traced. Change an input and the same code runs again on it.
Rule 2
Nothing is generated while you watch
No language model runs when you load a page. What you see was either computed ahead of time and checked, or is being computed right now by code in your browser.
Rule 3
Motion is evidence
Nothing moves unless the model changed something. No decorative animation. The RUN light is on only while code is executing; otherwise it reads STOP.
Rule 4
Checked against a reference
Each simulator's answers are tested against a plain reference implementation on random inputs, and it doesn't ship until they agree.
Where AI fits
A language model may help draft the prose and pick example inputs, offline, before a lesson is reviewed. It never draws a mechanism and never decides what a step shows. The frames come from running the code.
