Ultimate Legal Document Analysis

A powerful legal document analysis tool designed to analyze rental agreements and identify potential issues. Built with a Python FastAPI backend and React frontend.

Features

• Document Upload: Easily upload rental agreements for analysis
• Legal Analysis: Automatically analyze documents for potentially invalid or unusual clauses
• Essential Content Extraction: Identifies and extracts key information like parties, rental object, rent amount, and rental start date
• Vector-based Comparison: Uses advanced embedding techniques to compare with sample agreements and legal requirements
• AI-powered Analysis: Leverages OpenAI for intelligent document understanding

Getting Started

Prerequisites

• Docker and Docker Compose
• Python 3.8+
• Node.js 14+
• OpenAI API key

Environment Setup

1. Copy the template environment file:

   cp .env.template .env

2. Add your OpenAI API key to the .env file:

   OPENAI_API_KEY=your_api_key_here
   

Running with Docker

Start the application with Docker Compose:

docker-compose up

cd backend
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
pip install -r requirements.txt
python main.py

Frontend

cd frontend
npm install
npm run dev
