# AI Tutor Application

## Overview
The AI Tutor Application is an advanced tool designed to transform documents (e.g., PDFs) or user queries into interactive and structured lectures. Equipped with cutting-edge AI capabilities, this application provides voice narration, retrieval-augmented generation (RAG) chatbot functionality, and PDF generation for educational purposes.

## Features

### 1. **Lecture Generation**
- Converts PDF content or user-provided queries into structured lectures.
- Generates detailed outlines, sections, and content tailored to the user's learning objectives.
- Supports multiple styles (e.g., academic, casual) and includes examples if requested.

### 2. **Voice Narration**
- Synthesizes lecture content into audio using text-to-speech (TTS) technology.
- Offers multiple voice options to suit user preferences.

### 3. **RAG Chatbot**
- Provides a chatbot powered by Retrieval-Augmented Generation (RAG) to answer questions based on lecture or PDF content.
- Maintains session memory for personalized interactions.

### 4. **PDF Processing**
- Extracts and processes text from PDF files.
- Supports metadata extraction and text cleaning for better analysis.

### 5. **Interactive Gradio Interface**
- User-friendly interface for uploading documents, generating lectures, and interacting with the chatbot.
- Allows users to download generated lectures as PDFs or audio files.

### 6. **Customizable Learning Objectives**
- Users can specify learning objectives to tailor the lecture content.
- AI analyzes objectives to create relevant and engaging content.

## How It Works
1. **Input**: Upload a PDF document or provide a query/learning objective.
2. **Processing**: The application analyzes the input, generates a structured lecture, and optionally synthesizes audio.
3. **Output**: Download the lecture as a PDF or listen to the audio narration.

## Installation
1. Clone the repository:
   ```bash
   git clone <repository-url>
   ```
2. Navigate to the project directory:
