Description
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.

Could you build this?
Yes GrindLens queries LeetCode's public GraphQL API, maps solved problem IDs against known DSA taxonomy lists (NeetCode/Blind 75), and renders an analytics dashboard.

Same idea, different domain
A concrete adaptation of this idea for Legal
FactPattern
FactPattern ingests practice histories from bar prep question banks like AdaptiBar and UWorld to map an examinee's completed Multistate Bar Examination (MBE) questions against a rigorous taxonomy of underlying legal fact archetypes rather than just broad subject percentages. It reveals whether a student truly understands systemic triggers—such as the subtle interplay between race-notice recording acts and wild deeds—or is merely recognizing repeated surface facts, and surfaces the precise doctrinal gap to practice next.
Bar examinees routinely grind through 2,000+ multiple-choice questions tracking raw completion volume, yet existing bar prep providers only report crude topic scores (e.g., '62% in Torts') rather than diagnosing structural blind spots across recurring procedural and constitutional fact patterns.
