ConsentGuard AI - MIT CSN Hackathon

ConsentGuard AI is a powerful Chrome extension designed to help users navigate and understand complex privacy policies with ease. By analyzing webpage content and privacy agreements in real-time, it provides actionable insights, risk scores, and summaries to ensure users know exactly what they are consenting to.

Features

• Privacy Policy Analysis & Risk Scoring: Get immediate, AI-driven insights and a risk score for the website's privacy policy.
• Multilingual Support: A centralized, robust language engine supporting multiple languages for a fully localized user experience ("0 English" needed).
• Interactive Chat Assistant: Ask specific questions regarding the privacy policy and get contextual answers powered by Google's Gemini.
• Test Your Knowledge (Quiz Mode): Generate language-aware interactive quizzes directly from the document to test your understanding of the policy.
• Voice Capabilities: Interact hands-free with Speech-to-Text (STT) for asking questions, and Text-to-Speech (TTS) for listening to explanations.
• Modern User Interface: Sleek, responsive, and dynamic UI that seamlessly integrates into your browsing experience.

Installation Guide

Follow these steps to get both the backend API and the Chrome extension up and running locally.

1. Prerequisites

• Python 3.8+
• Google Chrome or a Chromium-based browser
• Obtain a Gemini API Key

2. Clone the Repository

git clone <repository-url>
cd T28_Team_Endra

3. Backend Setup

The backend is built with FastAPI and handles the AI analysis, STT, and robust data processing.

# Navigate to the backend directory
cd backend

# Create a virtual environment
python -m venv venv

# Activate the virtual environment
# On Linux/macOS:
source venv/bin/activate
# On Windows:
# venv\Scripts\activate

# Install dependencies 
# (Assuming a requirements.txt exists; install relevant packages like fastapi, uvicorn, google-generativeai, pydub, SpeechRecognition)
pip install -r requirements.txt

# Create a .env file and add your configuration (e.g., Gemini API key, CORS origins)
# Example: GEMINI_API_KEY=your_api_key_here

# Start the FastAPI server
uvicorn app.main:app --reload

The backend server should now be running on http://127.0.0.1:8000.
