AlgoNest is an AI-integrated coding platform built to revolutionize the way students and developers learn Data Structures and Algorithms (DSA). Acting as an intelligent tutor, AlgoNest provides step-by-step guidance, not just answers—promoting deep conceptual understanding and long-term skill development.

AlgoNest serves as your personal DSA tutor, assisting you in mastering coding problems through a rich suite of AI-driven features:

• 🧠 Hint Provision – Step-by-step hints to encourage problem-solving.
• 🔍 Code Review – Intelligent debugging with clear suggestions.
• 🧮 Optimal Solution Guidance – Thorough explanations with algorithmic intuition.
• 📊 Complexity Analysis – Insight into time/space trade-offs.
• 🧭 Approach Suggestion – From brute force to optimized techniques.
• 🧪 Test Case Assistance – Helps create additional test cases for edge coverage.

💡 AlgoNest is focused on learning, intuition building, and best practices—not spoon-feeding solutions.

git clone https://github.com/git-sumitchaudhary/AlgoNest-AI-POWERED-CODING-PLATFORM.git
cd AlgoNest-AI-POWERED-CODING-PLATFORM

cd backend
npm install

📄 Create a .env file:

PORT=5000
MONGO_URL=mongodb://localhost:27017/algonest
JWT_SECRET=your_jwt_secret_key
GEMINI_KEY=your_google_gemini_api_key
CLOUDINARY_CLOUD_NAME=your_cloudinary_cloud_name
CLOUDINARY_API_KEY=your_cloudinary_api_key
CLOUDINARY_API_SECRET=your_cloudinary_api_secret
REDIS_URL=redis://localhost:6379

▶️ Start backend server:

npm start

🟢 Runs at: http://localhost:5000

cd ../frontend
npm install
npm run dev

🟢 Runs at: http://localhost:5173

Once both servers are up:

🔗 Visit: http://localhost:5173

Start solving problems, interact with the AI, and boost your DSA skills 🚀
