Introduction

Codemble is a learning game that turns the code AI wrote for you into a galaxy you light up by understanding it.

The problem

People increasingly learn to code by building with AI agents — Claude Code, Codex — and end up with working apps they don’t understand. They can’t debug them, extend them, or explain them. Existing tools explain at you: passive tours, generated summaries. None of them make you prove you understood, and none teach the language as it appears in your own code.

The idea

Point Codemble at your project. It parses your code into a real structural graph — no guessing — and gives you two ways to look at that one graph: a 3D galaxy where modules are star systems, functions are planets and your entrypoint is Home, and a flat Map that lays out architecture and workflow as a diagram. Every node starts dim.

You explore, read what the parser knows before any model is asked, read explanations grounded in your actual source, learn the language idioms your code uses, and pass short checks whose answers come from the code’s real structure. Each region you truly understand lights up — permanently. The goal state is a fully lit galaxy.

Who it’s for

Early and intermediate coders who built something with AI and want to actually own it. Everything runs locally on your machine. Prose explanations are the one optional extra: bring your own Claude or OpenAI key, or run a local model through Ollama and send nothing anywhere.
