llms.txt generator

Build a valid llms.txt (llmstxt.org) for AI engines in seconds — fill the fields, copy or download. Runs fully in your browser.

Your llms.txt

Place the file at your site root: /llms.txt

What this tool checks

llms.txt is a markdown file placed at your domain root (/llms.txt) that gives AI engines a curated, plain-text index of your most important pages, following the llmstxt.org standard. It matters because AI crawlers handle clean, structured markdown more reliably than rendered HTML, so a well-formed llms.txt can point them at the canonical content you want cited. Engine adoption of the standard is still emerging, so publishing one mainly future-proofs your site.

What it looks at

H1 project name
The single required line — a top-level # heading naming your site — that tells an engine whose content this file describes.
Blockquote summary
A short > sentence under the H1 that gives the model a one-line description of what your site is about.
Curated link sections
H2 headings that group your most important URLs so engines index your canonical pages instead of crawling everything.
Per-link descriptions
A one-line note after each link explaining what the page covers, which helps a model decide the page is relevant to a query.
Optional section
An ## Optional block for secondary links an engine may skip when its context budget is tight, keeping the core list lean.
Plain-markdown format
The output is pure markdown served at /llms.txt, readable without executing JavaScript or parsing HTML, which is why AI crawlers prefer it.

How to use it

  1. Fill in the fields — your site name, a one-line summary, and the key URLs each with a short description.
  2. Generate the file, then copy it or download llms.txt.
  3. Upload it to your site root so it resolves at https://yourdomain.com/llms.txt, and confirm it loads.

Frequently asked questions

What is llms.txt and do AI engines use it?

llms.txt is a proposed standard (llmstxt.org) — a markdown file at your site root that gives AI models a curated index of your key pages. Adoption is still growing, but publishing one is low-cost and future-proofs your site for AI answer engines and RAG systems.

Where do I put the file?

Place it at your domain root so it resolves at /llms.txt — for example https://example.com/llms.txt. Some sites also add a fuller /llms-full.txt containing the actual page text.

Does llms.txt replace robots.txt or sitemap.xml?

No. robots.txt controls crawler access and sitemap.xml lists every URL for search indexing; llms.txt is a curated, human-readable guide to your best content for AI models. They serve different purposes and coexist.

Does my data leave my browser?

No. This generator runs entirely in your browser — you fill the fields and it builds the file client-side, so nothing is uploaded to a server.
