Hey everyone, I'm Shitanshu, built ChaosBench solo.
I kept noticing that "system design interview prep" mostly means watching someone else solve a problem, or reading a write-up of the right answer after the fact. Neither one actually tests whether you can hold up your own reasoning when someone pushes on it, which is what the real interview is.
So I built the AI to actually argue back. It asks about your specific choices, not a generic checklist, and it throws a live incident at your design once you've committed to it. You defend it or you find out where it breaks.
It's still very early and just me building this, so if something's rough or confusing, I genuinely want to hear it in the comments. That feedback is going straight into what I fix next.
