llms.txt Generator
Generate an LLM-friendly site index (llmstxt.org spec), fetch your site, analyze it with AI, produce llms.txt
Generate llms.txt
We fetch your site, read /sitemap.xml and the homepage links, then ask AI to produce a clean llms.txt.
What this tool does
Fetches your homepage and sitemap.xml, analyzes the link structure and content, and produces a clean llms.txt file following the llmstxt.org specification. The output is a Markdown index that ChatGPT, Claude, Perplexity, and other large language models can read to understand your site.
Who it's for: Webmasters, SEO professionals, and content publishers who want their site to be discoverable and well-represented in AI answer engines.
When to use
- •Make your documentation easier for ChatGPT, Claude, or Perplexity to reference in answers.
- •Give AI crawlers a clean, curated entry point instead of making them guess from your HTML.
- •Publish an llms.txt as part of Generative Engine Optimization (GEO) strategy.
- •Audit your site structure - the generated file shows how an LLM would classify your key pages.
How it works
- 1Enter your site URL.
- 2We fetch /sitemap.xml and your homepage, extracting titles, headings, and internal links.
- 3An AI model condenses the structure into the llmstxt.org Markdown format.
- 4Copy or download the file and upload it to your domain root as /llms.txt.
Tips
- •Host the final file at the root of your domain (e.g. https://example.com/llms.txt).
- •Keep the file under 10 KB; large files are truncated by some agents.
- •Re-generate after major site changes so the index reflects current content.
