Stop forgetting LeetCode solutions. PatternBank helps you retain what you practice by turning solved problems into confidence-based spaced repetition reviews. Solving hundreds of problems is not the same as remembering them.

Use PatternBank to: - Track algorithm problems by title, difficulty, confidence, notes, and patterns - Review problems on a spaced repetition schedule - Rate confidence from 1 to 5 stars after each review - Connect public LeetCode Activity to bring recent accepted submissions into Today - See due reviews, LeetCode solves, and completed work in one daily workflow - Track progress by pattern, review history, confidence trend, and 30-day projection - Exclude problems you do not want in the review queue - Start locally without an account, then sign in when you want cloud sync PatternBank is built for technical interview prep, algorithm practice, and long-term recall.
