llms.txt Generator & Validator

Enter your domain and get a ready-to-publish llms.txt built from your sitemap: your key pages, grouped into sections, in the format AI assistants expect. If you already publish one, we lint it too.

llms.txt is a curated map of your site for AI systems (ChatGPT, Claude, Perplexity). Google now checks for it in Lighthouse's agentic-browsing audit, making it an official AI-readiness signal.

What is llms.txt?

llms.txt is a plain-text file you publish at yourdomain.com/llms.txt. It gives AI assistants a curated map of your most important pages — in the order you want them read — using a simple Markdown format the models understand.

Why it matters

ChatGPT, Claude, and Perplexity, and Google's Lighthouse agentic-browsing audit, use llms.txt to find and understand your key pages. A good one improves how accurately AI answers represent your business (generative and answer-engine optimisation, GEO/AEO). It is a curated shortlist, not a sitemap dump: quality and order matter more than listing every URL.

What this tool does

It reads your sitemap on any platform — WordPress, Shopify, Wix, Squarespace, Webflow, or a custom framework — ranks your key pages and most recent posts (newest blog articles first), and produces a ready-to-publish draft. Less important overflow is placed in an ## Optional section that AI can skip. If you already publish an llms.txt, the tool validates it against the spec and lists any issues.

How to use it

  1. Enter your domain above and generate the draft.
  2. Curate it: keep the pages an AI should read first; trim the rest.
  3. Save it as a file named llms.txt at the root of your site so it is reachable at yourdomain.com/llms.txt.
