🛠️ Installation & Setup Guide

1. Clone the Repository

git clone https://github.com/your-username/notegenius.git
cd notegenius

2. Install Dependencies (Frontend & Backend)

# Install backend dependencies
cd backend
npm install

# Install frontend dependencies
cd ../frontend
npm install

---

3. Install Additional AI Libraries (Optional / Required per feature)

If you're using TensorFlow.js for summarization:

npm install @tensorflow/tfjs @tensorflow-models/universal-sentence-encoder

If you're using AssemblyAI (e.g., for speech-to-text):

npm install axios
# Then use AssemblyAI's API in backend routes

If you're using OpenAI API (e.g., for GPT summaries or MCQ generation):

npm install openai

If you want to use HuggingFace Transformers with Node.js:

npm install @xenova/transformers
# Note: This runs models in-browser (with WebAssembly), no server needed

---

4. Configure Environment Variables

Create a .env file in the /backend directory:

MONGO_URI=your_mongodb_connection_string
PORT=5000
OPENAI_API_KEY=your_openai_key
ASSEMBLYAI_API_KEY=your_assemblyai_key

🔐 Never expose this file publicly! Add .env to .gitignore.

# Terminal 1: Start backend
cd backend
npm start
