Built With
The Problem
You follow along and it makes sense. Then you close the tab and can't build anything from scratch.
Copilot writes it. ChatGPT explains it. You ship it. But what happens when the AI is wrong and you can't tell?
Platforms reward finishing modules, not understanding them. 100% completion with 0% retention.
The Solution
Our AI never hands you the answer. It asks the right questions until the solution clicks — because you found it.
Four progressive stages that gradually remove support. You start with guided exercises. You end building autonomously.
We evaluate correctness, code quality, problem-solving approach, conceptual understanding, and adaptability. Simultaneously.
Features
CodeForge detects when you're frustrated, identifies prerequisite gaps in real time, and adapts its approach. It never writes your code. It asks better questions until you write it yourself.
Write in any of 70+ languages. Execute instantly via sandboxed infrastructure. See stdout, stderr, execution time, and memory \u2014 the same feedback loop professional developers use.
Stage 1 fills in the blanks. Stage 2 gives you structure. Stage 3 gives you a spec. Stage 4 gives you nothing \u2014 just a problem and a deployment target.
Correctness is just the start. We evaluate how you approached the problem, how clean your code is, whether you can explain it, and whether you can modify it under pressure.
From your first Python script to production Rust. We cover the full spectrum.
Languages other platforms ignore:
Designed for the long game.
A 12-question adaptive diagnostic puts you at exactly the right level — no wasted time on basics you already know, no frustrating gaps.
Stage-aware lessons adapt to your current level. Fill-in-the-blank for foundations. Open specifications for advanced concepts.
Every concept concludes with a graded coding task. Real execution. Real feedback. Five dimensions of assessment.
SM-2 spaced repetition surfaces weak concepts at optimal intervals. Your streak keeps you accountable. The leaderboard keeps it competitive.
