PatternBank

New in PatternBank 2.0: LeetCode Activity sync, smarter review scheduling, Today workflow, Progress projection, and a cleaner mobile design.

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. PatternBank gives you a focused system for tracking what you solved, how confident you felt, which patterns were involved, and when you should review next.

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. It keeps the workflow simple: capture the problem, rate your confidence, review what is fading.

LeetCode Activity uses public profile activity. PatternBank does not ask for your LeetCode password.
