🔍 Overview

This application classifies URLs as Safe or Phishing by:

1. Extracting features from URLs (structural and content-based).
2. Training machine learning models (Random Forest, Logistic Regression, Naive Bayes).
3. Selecting Random Forest, which delivered ~96.9% accuracy.
4. Deploying via Flask, exposing a /predict API consumed by a JavaScript frontend.

💡 Key Features

• 🔬 ML-based detection: Random Forest performs best (~96.9% accuracy), compared to Logistic Regression (~93.4%) and Naive Bayes (~60.5%).
• 🧠 Feature engineering & EDA: Includes correlation heatmaps, pairplots, and pie‑charts for visualization.
• 🛠 GUI: Users can input a URL, trigger Flask backend, and view phishing predictions live.
• 🌐 Modern front-end stack: HTML/CSS for layout, vanilla JavaScript (or AJAX) for seamless interaction.
• ✅ Persistence: Trained model saved via pickle for deployment.
