🛠️ Technologies Used

• Backend: Django 4.2
• ML/NLP: Scikit-learn, NLTK, NumPy
• Frontend: HTML5, CSS, JavaScript, Bootstrap
• Database: SQLite (dev), PostgreSQL ready

🎯 AI Workflow

1. Text cleaning & tokenization
2. Stop-word removal
3. Stemming (Porter)
4. TF-IDF vectorization
5. Cosine similarity ranking
