LeetNext

Stop aimlessly grinding coding problems. Master data structures and algorithms with targeted, algorithmic review. LeetNext is an intelligent, privacy-first companion browser extension designed to optimize your technical interview preparation. Instead of repeating problems you already know or forgetting complex patterns you solved weeks ago, LeetNext automates your revision schedule using an adaptive memory-decay engine. Key Features Automated Submission Tracking: Instantly syncs with your LeetCode profile to capture your historical problem attempts, runtime metrics, and language choices without manual data entry. Intelligent Spaced-Repetition: Utilizes localized recall-decay algorithms specifically tuned for code complexity (e.g., tracking decay on hard topics like segment-trees or dynamic-programming). It flags exactly when a problem's structural retention enters a critical state. On-Device AI Analysis: Interfaces natively with your browser's local runtime intelligence (like Chrome's built-in Gemini Nano model) to evaluate code snippets and categorize conceptual bottlenecks directly on your machine. Actionable "What's Next?" Dashboard: Provides a clear, prioritized daily queue of problems whose retention schedules require immediate revisiting to reset your learning curves. 🔒 100% Local & Privacy-First Your code solutions and progress metrics are entirely your own. LeetNext does not operate remote databases or track your data on external cloud servers. Streamline your practice, lock down your weak spots, and clear your next technical interview with perfect retention.
