✅ AUTO-TRACK SUBMISSIONS
Every accepted solution is captured instantly — code, language, runtime, memory, and timestamp. No copy-pasting. No manual logging. Just solve and go.

🤖 AI-POWERED STUDY NOTES
Get instant AI analysis on every submission:
• Key algorithm patterns identified
• Step-by-step dry-run walkthrough
• Time & space complexity breakdown
• Markdown-formatted notes you can review anytime
Powered by Groq (bring your own API key — stored locally, never on our servers).

🏷️ PATTERN RECOGNITION
Organize problems by 50+ algorithm patterns — Two Pointers, Sliding Window, Dynamic Programming, BFS/DFS, and more. See which patterns you've mastered and where you need practice.

🔍 ADVANCED SEARCH
Query your problem library like a pro:
