📌 Project Overview

The Plagiarism AI Detection & Rewriting System is an advanced open-source application that detects text similarities and identifies potential plagiarism, while offering AI-powered text rewriting capabilities to help users produce original content.

This platform was built as a third year mini-project by Debasmita, Manisha and Joita. It operates completely free of charge, leveraging a privacy-first local AI engine powered by Ollama (Llama 3) and FastAPI to ensure your data never leaves your computer.

🚀 Features

• AI Plagiarism Scanner: Paste your text directly into our clean, focused uploader to instantly calculate similarity scores and plagiarism removal metrics.
• Context-Aware Rewriting: Automatically rewrite flagged content using our local LLM integration to improve originality while preserving meaning.
• Dedicated History Page: Keep track of recent scans and review past rewrites on a centralized history dashboard.
• Modern UI/UX: Responsive, accessible, and animated interface featuring dark mode support and interactive tooltips.
• 100% Free & Open Source: Built by students, for students. Enterprise-grade security and zero subscription fees.

⚙️ Installation & Setup

Follow these steps to run the project locally. You will need two terminal windows running simultaneously.

1. Backend Setup

Open your first terminal and navigate to the backend directory:

cd backend

Create and activate a virtual environment (Windows):

python -m venv .venv
../.venv/Scripts/activate

Install dependencies:

pip install -r requirements.txt

Start the FastAPI server:

uvicorn app.main:app --reload

The backend will run on http://localhost:8000.

2. Frontend Setup

Open your second terminal and navigate to the frontend directory:

cd frontend-new/new-look

Install Node.js dependencies:

npm install
# or if using bun
bun install

Start the Vite development server:

npm run dev
# or if using bun
bun run dev

Access the application at http://localhost:5173.
