🧠 Human vs AI Essay Classifier

A Flask-based web app that detects whether an essay is AI-generated or human-written using machine learning and natural language processing (NLP).

🚀 Features

• 🔍 Classifies essays as Human or AI-generated
• 📝 Simple and clean web interface built with Flask
• 📊 Machine Learning model trained on text features
• ⚡ Fast predictions with scikit-learn & NLP tools

🛠️ Tech Stack

• Backend: Flask
• ML Libraries: Scikit-learn, Naive Bayes, NLTK, Textstat
• Visualization: Matplotlib, Seaborn, WordCloud
• Data Handling: Pandas, NumPy

🎨 Web Interface 📝 Input Page

Users can paste or type an essay into the text box.
