GrindLens

i solved 400+ LeetCode problems, rating touched 1720. Someone asked me what topics I'm actually weak at and I froze. Had a number in my head, not an answer. That gap is why GrindLens exists. It checks your actual LeetCode history, tracks progress across sheets like NeetCode 150, Blind 75, and Striver A2Z, and tells you exactly what to solve next based on your real weak patterns, not just a solved count going up. Built it after months of grinding without any real read on where I stood. 125+ signups so far, completely free right now. Paste your LeetCode username to see a quick weak-topic snapshot instantly, no login needed for that part, sign for full sheet tracking and progress saved over time.
