Sitemap to llms.txt – Generate structured llms.txt files from any sitemap without a CMS

Summary: SitemapToLLMs converts XML or HTML sitemaps into semantically organized llms.txt files with intelligent filtering, readable sections, and priority ordering. It automates creating llms.txt files to help large or custom websites communicate their structure to large language models (LLMs).

What it does

The tool transforms sitemaps into structured llms.txt files by filtering URLs, naming sections semantically, grouping legal pages, and ordering content by priority. Users simply paste their sitemap to generate the file without needing a CMS.

Who it's for

It is designed for website owners and developers who want to provide LLMs with a clear, up-to-date overview of their site’s structure, especially those managing large or custom web stacks.

Why it matters

SitemapToLLMs addresses the lack of a standardized way for websites to explain their content to AI discovery tools, simplifying the creation of llms.txt files that improve LLM understanding and indexing.
