A simple document interaction system using Retrieval-Augmented Generation (RAG) with Streamlit and Google's Gemini AI.

## Features

- Upload text documents (.txt files)
- Ask questions about your documents
- Get AI-powered answers with source citations
- Persistent vector database storage
- Clean web interface

## Setup

### With Docker (Recommended)

1. Clone the repository:
```bash
git clone https://github.com/tusiim3/RAG-Document-System.git
cd RAG-Document-System
```

2. Copy `.env.example` to `.env` and add your Google API key:
```bash
cp .env.example .env
```

3. Run with Docker Compose:
```bash
docker-compose up --build
```

4. Open http://localhost:8501 in your browser

### Without Docker

1. Clone the repository:
```bash
git clone https://github.com/tusiim3/RAG-Document-System.git
cd RAG-Document-System
```

2. Install dependencies:
```bash
pip install -r requirements.txt
```

3. Copy `.env.example` to `.env` and add your Google API key:
```bash
cp .env.example .env
