This free llms.txt generator builds a clean /llms.txt file that tells AI crawlers — ChatGPT, Claude, Perplexity, and Gemini — which pages on your site matter most and what each one covers. Enter your site details, add sections and links, and copy or download a ready-to-publish file for your domain root. No signup, nothing leaves your browser.
How to use the llms.txt generator
- Enter your site name and a one-line summary of what the site is about.
- Add a section for each group of pages — for example Guides, Tools, or Docs.
- In each section, add one link per line as
URL | Title | short description. The description is optional but recommended. - Copy the generated file, or download it as
llms.txt. - Upload it to your domain root so it is reachable at
https://yoursite.com/llms.txt.
What is llms.txt and why it matters
llms.txt is a proposed markdown standard — a curated map for large language models — that you place at your domain root. Where robots.txt controls which crawlers may access your site and sitemap.xml lists every URL, llms.txt does something different: it points AI systems at your best content with a short description of each, so they read the right pages instead of guessing. It is part of the same shift toward generative engine optimization that makes how AI citation systems work worth understanding. Pair a published llms.txt with an llms-full.txt — the full text of your key pages — for maximum clarity.

Frequently Asked Questions
Where do I put the llms.txt file?
At the root of your domain, so it resolves at https://yoursite.com/llms.txt — the same location convention as robots.txt. On WordPress you can add it via your host’s file manager, an SEO plugin that supports custom root files, or a small redirect/rewrite rule. It should return plain text with a text/plain content type.
Is llms.txt an official standard yet?
It is a proposed, community-driven convention rather than a formally ratified standard, and support varies by AI provider. Publishing one is low-effort and low-risk: at worst it is ignored, and at best it helps AI systems find and correctly describe your most important pages. Many AI-focused tools and sites already ship one.
How is llms.txt different from robots.txt and sitemap.xml?
robots.txt says who may crawl and what is off-limits. sitemap.xml lists all your URLs for completeness. llms.txt is curated and opinionated — it highlights your best, most useful pages with a short description of each, so language models prioritize the right content instead of treating every URL equally.
What should I include in it?
Lead with your most valuable pages: cornerstone guides, documentation, tools, and key product or service pages. Group them into clear sections and give each a short, literal description. Quality beats quantity — a focused file of your best 20–50 pages is more useful to a model than an exhaustive dump of every URL.
Is this generator free and private?
Yes — completely free, no account, no limits, and everything runs in your browser so nothing you type is sent to a server. It is part of the free Plain Intelligence resource hub alongside the schema, robots.txt, and sitemap generators.
