  description

  Stop forgetting DSA problems you've already solved.
  
  DSA Spaced Repetition uses the proven SM-2 spaced repetition algorithm to schedule reviews at optimal intervals, so you retain what you learn with minimal effort.
  
  Works on LeetCode, CSES, and more.
  
  HOW IT WORKS
  • Visit any problem page and mark it as solved
  • Rate your recall: Forgot, Hard, Good, or Easy
  • The algorithm schedules your next review at the perfect interval
  • Problems you struggle with come back sooner; easy ones fade away
  • Drag the widget anywhere on the page to keep it out of your way
  
  REVIEW QUEUE
  • See today's due problems at a glance in the popup
  • Click any problem to jump straight to it
  • Track your daily streak and progress
  
  ANALYTICS DASHBOARD
  • Activity chart for the last 30 days
  • Difficulty breakdown (Easy / Medium / Hard)
  • Review forecast for the next 14 days
  • Full problem table with ease factors, intervals, and status
  • Track mastered vs. in-progress problems
  
  KEY FEATURES
  • Works on multiple platforms — LeetCode, CSES, and more
  • SM-2 algorithm — the same algorithm used by Anki
  • Draggable widget — move it anywhere on the page
  • 100% offline — all data stored locally on your device
  • Syncs across devices via Chrome's built-in sync
  • Zero accounts, zero sign-ups, zero data collection
  • Clean dark UI that blends with coding platforms
  • Lightweight — no impact on page performance
  
  PRIVACY
  This extension stores everything locally. No data is sent to any server. No analytics, no tracking, no accounts. Your data stays on your device.
  
  Perfect for anyone preparing for coding interviews, competitive programming, or just wanting to retain DSA solutions long-term.
