How it works
three steps, no shortcuts01
Pick a concept
From a path you're following, or something you uploaded yourself. Concepts carry a misconception inventory drawn from how real learners get it wrong.
02
Get interrogated
knownode probes, it doesn't lecture — adaptive difficulty, no answers handed over, adversarial once you've shown you're past the basics.
03
Prove it, don't just recall it
Mastery advances only when your answer holds up under a rubric — and decays over time if you don't revisit it. The ladder is the only progress bar that matters.
