Getting Started with Crawl4AI

To begin using Crawl4AI, follow these steps:

1. Installation:

   Install Crawl4AI using pip:

   pip install crawl4ai
   

2. Setup:

   Run the setup command to install browser dependencies:

   crawl4ai-setup
   

3. Basic Usage:

   Here's a simple example to crawl a webpage:

   import asyncio
   from crawl4ai import AsyncWebCrawler
   
   async def main():
       async with AsyncWebCrawler() as crawler:
           result = await crawler.arun(url="https://example.com")
           print(result.markdown)
   
   asyncio.run(main())
   

This script initializes the crawler and retrieves the Markdown-formatted content of the specified URL.

Conclusion

Crawl4AI stands out as a powerful, open-source tool for web crawling, offering features tailored for AI applications. Its speed, flexibility, and AI-optimized output make it an excellent choice for developers and researchers seeking to harness web data effectively.
