# PDF to Podcast

## Overview

This project provides a tool to convert any PDF document into a podcast episode! Using Google's Gemini for dialogue generation and OpenAI's text-to-speech models, this tool processes the content of a PDF, generates a natural dialogue suitable for an audio podcast, and outputs it as an MP3 file.

## Features

- **Convert PDF to Podcast:** Upload a PDF and convert its content into a podcast dialogue.
- **AI-Powered Dialogue:** Uses Google's Gemini LLM to create engaging, natural conversations.
- **High-Quality Audio:** Leverages OpenAI's text-to-speech for lifelike voices.
- **User-friendly Interface:** Simple interface using Gradio for easy interaction.

## Usage

   python main.py
   ```
   This will launch a Gradio interface in your web browser.
