AI researchers needing a tool to extract structured web data for training and enhancing large language models

About Crawl4AI

Crawl4AI is an open source web crawler and scraper designed for large language models, AI agents, and data pipelines. It generates clean Markdown suitable for retrieval-augmented generation (RAG) pipelines or direct ingestion into LLMs, performs structured extraction using CSS, XPath, or LLM-based methods, and offers advanced browser control with features like hooks, proxies, stealth modes, and session reuse. The platform emphasizes high performance through parallel crawling and chunk-based extraction, aiming for real-time applications. Crawl4AI is fully open source, providing free access without forced API keys or paywalls, and is highly configurable to meet diverse data extraction needs. Its core philosophies include democratizing data by being free to use, transparent, and configurable, and being LLM-friendly by providing minimally processed, well-structured text, images, and metadata for easy consumption by AI models.
