# ARGObot: Academic Advising Chatbot Powered with AI Agent

ARGObot is a custom-built Retrieval-Augmented Generation (RAG) chatbot designed to answer university-related questions using either OpenAI or Google Gemini. It reads from official student handbooks and optionally supplements answers using Google Search.

## Features

-  Switchable backend (OpenAI or Gemini)
-  LangGraph for stateful chat memory
-  RAG pipeline using LangChain + ChromaDB
-  Clean Streamlit interface
-  Modular file structure
-  Secure `.env`-based configuration

##  Getting Started

### 1. Clone the Repository
```bash
git clone https://github.com/yourusername/argobot.git
cd argobot
```

### 2. Install Requirements
```bash
pip install -r requirements.txt
```

### 3. Configure Environment
Create a `.env` file based on `.env.example`:
```env
MODEL_PROVIDER=openai
OPENAI_API_KEY=your-openai-key
GOOGLE_API_KEY=your-gemini-key
PDF_PATH=resources/22_studenthandbook-22-23_f2.pdf
```

### 4. Run the App
```bash
streamlit run src/main.py
```

## How It Works

1. Loads a PDF knowledge base (e.g., UWF Student Handbook)
2. Splits it into text chunks using LangChain
3. Embeds and stores chunks in a vector store
4. Uses LangGraph to manage conversation state
5. Responds via OpenAI or Gemini based on your configuration
