Codemaster Algorithm Lear

Stop grinding LeetCode randomly. Start learning algorithms scientifically.

CodeMaster is an intelligent learning assistant that transforms your algorithm practice into a personalized, retention-optimized system. Unlike traditional problem
lists, CodeMaster uses proven cognitive science principles to ensure you actually master algorithms—not just solve them once and forget.

🧠 SMART SPACED REPETITION

Never forget a pattern you've learned. Our Leitner-based system automatically schedules problem reviews at scientifically optimal intervals:

• 5-Box Progression System: Problems advance through mastery levels (Daily → Every 3 days → Weekly → Monthly → Archived)
• FSRS Algorithm Integration: Personalized forgetting curves adapt to YOUR individual learning pace
• Intelligent Review Scheduling: Due problems surface automatically—no manual tracking needed
• Decay-Aware Tracking: Problems you haven't seen in months get prioritized to refresh your memory

Returns from a 2-year break? CodeMaster knows what you've forgotten and rebuilds your foundation efficiently.

📊 ADAPTIVE LEARNING ENGINE

Your sessions evolve with your performance:

• Dynamic Difficulty Adjustment: Problems get harder as you improve, easier when you struggle
• Pattern Ladder System: Master algorithms progressively within each category (Arrays → Two Pointers → Sliding Window → Advanced)
• Tag Mastery Tracking: See exactly which topics you've mastered and which need work across 50+ algorithm patterns
• Multi-Factor Problem Selection: 9+ criteria analyzed to choose optimal next problems (mastery level, recent performance, learning velocity, weak areas)

No more guessing which problem to do next. CodeMaster always knows.

🎯 SEAMLESS LEETCODE INTEGRATION

Practice on LeetCode, track progress in CodeMaster:

• Automatic Problem Capture: Click one button to log attempts—no manual data entry
• Built-In Timer: Track time spent without switching tabs
• Smart Hint System: 50+ algorithm-specific strategy guides with progressive hint disclosure
• Content Script Overlay: Lightweight interface floats on LeetCode pages—zero friction

Works on every LeetCode problem page. No account linking required.

📈 INSIGHTFUL ANALYTICS DASHBOARD

Data-driven progress tracking that actually helps:

• Tag Mastery Heatmaps: Visualize strengths and weaknesses across algorithm categories
• Box Distribution Charts: See your retention pipeline at a glance
• Session History Analytics: Accuracy trends, time-per-problem metrics, productivity insights
• Learning Velocity Tracking: Measure improvement rate per topic
• Pattern Coverage Reports: Ensure balanced topic exposure (70% ladder completion requirement)

Turn vague "I should do more DP" into concrete "I'm 60% through DP Easy, 30% Medium—here's what to focus on."

🔒 PRIVACY-FIRST DESIGN

Your learning data belongs to you:

• 100% Local Storage: All data stays on your device via IndexedDB
• Zero Cloud Dependencies: No servers, no accounts, no tracking
• No Data Transmission: Extension never sends anything anywhere
• Complete Control: Export, delete, or reset your data anytime

We can't see your data because we never collect it.

🚀 PERFECT FOR

Interview Prep: Spaced repetition ensures long-term retention, not short-term cramming

Returning Users: Studied 4 months → Got job → Interviewing again 2 years later? Start where you left off with intelligent recalibration

Structured Learners: Pattern ladders provide clear progression paths through algorithm topics

📚 SCIENCE-BACKED LEARNING

Based on research-proven principles:

• Spaced Repetition: Review at optimal intervals (Ebbinghaus forgetting curve)
• Graduated Difficulty: Start easy, increase challenge as competence grows (Zone of Proximal Development)
• Interleaved Practice: Mix topics to improve discrimination and retention
• Retrieval Practice: Active recall strengthens memory more than re-reading solutions

CodeMaster applies learning science to software engineering education.
