🚀 A modern PDF Comparison Tool built with Django (Backend) & React + Vite (Frontend).
Easily upload, compare, and track differences between two PDF files with an intuitive UI and history feature.

• 📤 Upload two PDF files for comparison
• 🔍 Extracts and compares text to highlight differences
• 📝 Stores comparison history in the database
• 📊 View previous comparisons and reload them
• 🎨 Clean React UI with Material UI and React-PDF

• Decoupled Frontend & Backend
  • frontend/ – React + Vite app for UI
  • backend/ – Django REST Framework for APIs
• Static File Integration – React build served via Django
• Reusable APIs – Upload, Compare, and History endpoints
• Simple DB – SQLite for local storage (can be replaced with Postgres/MySQL)

1. 📄 Upload PDFs – User selects two PDF files
2. 🧠 Text Extraction – Backend extracts text from both PDFs
3. 🔍 Comparison – Differences are computed and summarized
4. 🗃️ History Storage – Comparison details are saved in DB
5. 📜 Results Display – Side-by-side PDF view with difference summary
