A web-based app that helps users learn and review coding problems effectively using spaced repetition, personalized learning plans, and topic tracking.
Many users struggle to consistently improve their coding skills on platforms like Leetcode because:
- They lack a structured learning plan, often randomly selecting problems.
- It’s hard to track progress by topic or focus on weak areas.
- Practice isn’t always personalized, leading to slow learning and repeated mistakes.
The Leetcode RAG Agent addresses these challenges by:
- AI-Powered Learning: AI agent assigns problems, evaluates answers, and adapts the learning plan based on performance.
- Personalized Practice: Users can practice specific topics, adjust daily learning targets, and receive tailored recommendations.
- Spaced Repetition: Problems are reviewed intelligently to maximize retention and reinforce weak areas.
- Progress Tracking: All performance data is securely stored, allowing users to monitor improvements over time.
