How It Works

Spaced Repetition for DSA Problems

DSA Memoizer uses the science of spaced repetition to help you truly master algorithms and data structures.

Step 1
Mark for Review
When you need help solving a problem

Whenever you take help (watch a video, read the solution, or peek at the code), just click the "Mark for Review" button.

Step 2
Wait for Your Set Interval
Let your brain process the information

The extension will automatically remind you after your chosen interval to try solving it again — this time without help.

Step 3
Solve Again
Cement your understanding

Solve the problem from memory. Mark as solved or schedule another review if needed.

About the Developer

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!
