CodeMentor AI — Agentic Coding Tutor
Chat with a tutor, run its code right there. 17 visual steppers + spaced repetition.
// why: Chat, runner, and visualizer lived in 3 tabs — nothing showed what actually executes.
- Chat + run in one place: every tutor answer has a runnable Monaco editor attached
- 17 synced sims: BST to system design, line-highlighted with the tracer
- Never dead: 4-tier model cascade ends in offline mode, ~600 tests green
