LeetRevisor

Supercharge your LeetCode prep with targeted spaced repetition, custom pattern tagging, and automated submission syncing.

Mastering data structures and algorithms is about retention, not just solving a problem once and forgetting it. LeetRevisor transforms your LeetCode history into an automated, highly-targeted spaced repetition system. How it works: Connect your LeetCode username, and LeetRevisor securely pulls in your past accepted submissions. Instead of relying on random daily challenges, the extension algorithmically surfaces the exact problems you haven't reviewed recently, ensuring you never forget a pattern. Key Features: Seamless Spaced Repetition: Instantly jump into a continuous loop of problem revisions. Just solve, click "Mark as Revised," and immediately get your next problem. Targeted Revision Pools: Don't just blindly study. Filter your study queue by a specific Timeframe (e.g., last 30 days), Difficulty, or Custom Pattern. Custom Pattern Tagging: LeetCode's default tags are often spoilers. LeetRevisor lets you tag problems with your own custom patterns (e.g., "Two Pointers", "Sliding Window", "Blind 75") so you can study exactly what you want, when you want. Privacy First (Local Storage): Your revision data, streaks, and tags never leave your device. Everything is stored locally in your browser's database. Data Portability: Easily export and import your revision history as a JSON backup so you never lose your progress. Stop grinding aimlessly. Start studying intelligently with LeetRevisor.
