Crawl4AI

About

Crawl4AI provides a sophisticated two-phase architecture for transforming complex websites into clean, developer-friendly documentation. By separating bulk parallel crawling from content post-processing, it efficiently captures entire site structures while removing extraneous elements like navigation menus, headers, and footers. The skill enriches output with AI-generated metadata for descriptions and keywords while maintaining pure markdown files, making it an essential tool for creating local knowledge bases, analyzing site structures, or preparing web content for LLM ingestion.
