CacheHit

Spaced repetition for LeetCode and NeetCode. Rate problems when you solve them, review them when they are due.

CacheHit is spaced repetition for LeetCode and NeetCode. After you get Accepted, rate how hard the problem felt. CacheHit schedules the next review with FSRS, so weak problems come back sooner and strong ones wait longer. Open the popup when you are ready to clear your due queue. HOW IT WORKS 1. Solve a problem on LeetCode or NeetCode 2. Rate it: Again / Hard / Good / Easy 3. Review it again when it is due WORKS ON • LeetCode (after Accepted) • NeetCode (after Accepted) FEATURES • Daily review queue with Again, Hard, Good, Easy • Built-in roadmaps: Blind 75, NeetCode 150, NeetCode 250 • Streaks, XP, and progress stats • Notes on each card • Optional private sync through your own GitHub Gist • Import and export backups • Dark and light themes WHY CACHEHIT You already solved Two Sum last month. That does not mean you will remember it in an interview. CacheHit keeps patterns in memory with scheduled reviews instead of random grinding. Privacy: your cards and stats stay in your browser by default. GitHub Gist sync is optional and uses a private Gist you own.
