GrindLens

What is GrindLens?

You can solve hundreds of LeetCode problems and still not know what you're actually good at. GrindLens looks at your solving history differently. It maps the problems you've solved to DSA patterns, shows where you've built real coverage and where you're still struggling, tracks your progress across popular sheets, and helps you figure out what to practice next. because eventually, “457 solved” stops telling you much.
