DSA Memoizer is a free Chrome extension designed to enhance your problem-solving skills in data structures and algorithms (DSA) through effective review practices. Targeted at users of LeetCode and GeeksforGeeks, this tool introduces a smart reminder system that prompts users to revisit problems they've marked for review after a set period. This helps users transition from passive knowledge to active retention, ensuring they truly master the concepts instead of merely recalling solutions.

The extension features a simple interface with a floating button on problem pages, allowing users to easily mark problems for review after seeking help. Users receive reminders after four days to attempt the problem independently, fostering a consistent study habit. Additional functionalities include marking problems as solved or choosing to resolve them again, making it a versatile tool for students and job-seekers preparing for coding interviews.
