GrindLens
You solved it. But did you actually learn the pattern?
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.
i had this weird problem with leetcode.
my solve count kept going up.
100 → 200 → 300 → 400+
and somehow i still couldn't answer a pretty basic question:
“what are you actually bad at?”
someone asked me that after i'd already solved 400+ problems and i just sat there lol.
i knew my rating.
i knew my streak.
i knew which sheets i'd finished.
i just didn't know what i actually knew.
that question kinda stayed in my head, so i started building GrindLens.
it looks at your actual solving history and tries to make sense of it at the pattern level. what you've covered, what you keep struggling with, what you've barely touched, and eventually what you should probably solve next.
i've been using it on my own profile for the last few weeks and have been changing things based on what people actually use / complain about.
if you grind leetcode, i'd be curious what your answer to that question is:
what are you actually bad at?
