Multi-Agent YouTube Research & Blog Writer

A simple multi-agent system built with CrewAI that researches YouTube videos and automatically generates blog posts based on video content.

Overview

This project uses two AI agents working in sequence:

  1. Blog Researcher - Finds and analyzes YouTube videos on specified topics
  2. Blog Writer - Creates engaging blog content based on the research

Features

  • 🎥 Search and analyze YouTube channel content
  • 🤖 Two specialized AI agents with distinct roles
  • 📝 Automatic blog post generation in Markdown format
  • 🔄 Sequential workflow with memory and caching
  • ⚡ Built on CrewAI framework with GPT-4o-mini

Setup

  1. Clone the repository

    git clone https://github.com/Tusharbecoding/multi-youtube-agent
cd multi-youtube-agent

  2. Create virtual environment

    python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

  3. Install dependencies

    pip install -r requirements.txt

  4. Configure environment Create a .env file in the root directory:

    OPENAI_API_KEY=your_openai_api_key_here

  5. Update YouTube channel Edit tools.py to specify the target YouTube channel:

    yt_tool = YoutubeChannelSearchTool(youtube_channel_handle="@yourchannel")

Usage
