Build Real DSA Mastery,
Not Just Streaks
Turn "I saw the solution" into "I own the solution" with a smart reminder system for LeetCode and GeeksforGeeks.

Spaced Repetition for DSA Problems
DSA Memoizer uses the science of spaced repetition to help you truly master algorithms and data structures.
Whenever you take help (watch a video, read the solution, or peek at the code), just click the "Mark for Review" button.
The extension will automatically remind you after your chosen interval to try solving it again — this time without help.
Solve the problem from memory. Mark as solved or schedule another review if needed.

Built by a Developer, for Developers
Hi, I'm a software engineer passionate about creating tools that help developers learn and grow. I built DSA Memoizer after struggling with the same problem myself - seeing solutions but not truly mastering them.
My goal is to create simple, effective tools that solve real problems for developers. If you have any feedback or suggestions, I'd love to hear from you!
