About this pageAI generated

This page explains how to convert webpages into structured data that LLMs can effectively use. It introduces webclaw, a web extraction engine written in Rust that transforms raw HTML into clean, structured content. Typical webpages contain 50,000-200,000 tokens of raw HTML, but actual content represents only 500-2,000 tokens. The remainder consists of structural and UI elements that waste tokens and pollute vector spaces in RAG pipelines. Webclaw implements a 9-step optimization pipeline that removes navigation, footers, cookie banners, sidebars, and other noise, reducing token usage by 67%. This improves retrieval quality and preserves context windows in LLM agents.
