## 📰 ➡️ 🎙️ Blog to Podcast Agent
|
||||
This is a Streamlit-based application that allows users to convert any blog post into a podcast. The app uses OpenAI's GPT-4 model for summarization, Firecrawl for scraping blog content, and ElevenLabs API for generating audio. Users simply input a blog URL, and the app will generate a podcast episode based on the blog.
|
||||
|
||||
## Features
|
||||
|
||||
- **Blog Scraping**: Scrapes the full content of any public blog URL using Firecrawl API.
|
||||
|
||||
- **Summary Generation**: Creates an engaging and concise summary of the blog (within 2000 characters) using OpenAI GPT-4.
|
||||
|
||||
- **Podcast Generation**: Converts the summary into an audio podcast using the ElevenLabs voice API.
|
||||
|
||||
- **API Key Integration**: Requires OpenAI, Firecrawl, and ElevenLabs API keys to function, entered securely via the sidebar.
|
||||
|
||||
## Setup
|
||||
|
||||

|
||||
