Web Crawler with Content Analysis

A web crawler tool built with PocketFlow that crawls websites and analyzes content using LLM.

Features

• Crawls websites while respecting domain boundaries
• Extracts text content and links from pages
• Analyzes content using GPT-4 to generate:
  • Page summaries
  • Main topics/keywords
  • Content type classification
• Processes pages in batches for efficiency
• Generates a comprehensive analysis report

Installation

1. Clone the repository
2. Install dependencies:

   pip install -r requirements.txt
   

3. Set your OpenAI API key:

   export OPENAI_API_KEY='your-api-key'
   

Usage

Run the crawler:

python main.py

You will be prompted to:

1. Enter the website URL to crawl
2. Specify maximum number of pages to crawl (default: 10)

The tool will then:

1. Crawl the specified website
2. Extract and analyze content using GPT-4
3. Generate a report with findings
