⚖️ LegalAI – Intelligent Legal Assistance Platform

📌 Overview

LegalAI is a machine learning-powered web application that helps users understand legal issues by automatically classifying legal complaints into different case categories and recommending the appropriate court. The application uses Natural Language Processing (NLP) with TF-IDF vectorization and a Naive Bayes classifier to analyze user-entered legal complaints and provide relevant legal guidance.

The system is designed to simplify access to legal information by assisting users in identifying the nature of their legal issues and providing appropriate recommendations.

🧠 Machine Learning Workflow

1. User enters a legal complaint.

2. The input text is preprocessed.

3. TF-IDF converts the text into numerical feature vectors.

4. The trained Naive Bayes model predicts the legal case category.

5. The application displays:

   • Predicted Case Category
   • Recommended Court
   • Applicable Legal Sections
   • Required Documents
   • Lawyer Recommendations
