My AI Mentor Warned Me About a Bug Before I Even Ran the Code I used to think personalized learning meant picking your difficulty level. I was wrong. Real personalization means your tools remember you — your exact mistakes, your patterns, your blind spots. That's what we built with Kernel's Slap. What is Kernel's Slap? Kernel's Slap is an AI coding mentor that uses Hindsight memory to remember how you think, fail, and improve — across every session, every problem, every mistake. Unlike LeetCode or HackerRank, it never forgets you. The main moving parts: Frontend: Next.js + Monaco Editor (same editor as VS Code) Backend: FastAPI (Python) Memory: Hindsight — retain(), recall(), learn() LLM: Groq (qwen3-32b) — fast inference, no waiting The Core Problem We Solved Every coding platform today is stateless. You fail the same off-by-one error on Monday. You fail it again on Wednesday. The platform has no idea. It gives you the same generic hint both times as if it has never seen you before. T
