Free llms.txt Generator: Tell AI Crawlers What to Read
An llms.txt file is a Markdown file at your site root that tells AI assistants like ChatGPT, Claude, and Perplexity what your site is about and which pages to read first. Fill in the fields below and this generator builds a valid llms.txt you can upload in two minutes.
Everything runs in your browser. Nothing you type leaves this page.
What does this tool create?
This tool creates a complete, correctly formatted llms.txt file following the emerging llms.txt standard: an H1 with your site name, a blockquote summary that AI engines can quote verbatim, an optional about section, an H2 section listing your key pages as Markdown links with one-line descriptions, and your contact and profile links. The output is plain Markdown served as text — exactly what the standard specifies — so you can copy it or download the file and upload it to your site root without editing anything. The blockquote is the highest-leverage line in the file: it's the sentence you're handing AI assistants to describe your business, so the form prompts you to write it as a complete, factual claim rather than a slogan.
How to use it (3 steps)
- Fill in your site name and summary, then list your 5-10 most important pages with one-line descriptions.
- Generate and download your llms.txt file.
- Upload it to your site root so it's live at yourdomain.com/llms.txt, and reference it in robots.txt if you like.
Why llms.txt is the cheapest AI visibility win available
AI assistants work under tight context budgets — when one lands on your site, it can't read everything, so it reads what it can find fast. llms.txt hands it a curated map: this is who we are, this is what we do, these are the pages that matter. The standard costs nothing to adopt, takes minutes to ship, and carries zero downside risk, which is a combination that almost nothing else in SEO offers. Anthropic publishes one for its own docs, Perplexity checks for them, and adoption keeps spreading through the AI tooling ecosystem. I publish one on this site and add one to every AI-visibility client engagement, because the sites that describe themselves accurately get described accurately in return — the ones that don't leave AI engines to guess from whatever fragments they retrieve. For the full background, read my guide on what llms.txt is and how to set it up. Once yours is live, confirm AI crawlers can actually reach your site with the AI Crawler Robots Tester — an llms.txt behind a blocked GPTBot helps nobody.

FAQ
llms.txt is a Markdown file at your site root that gives AI assistants a curated summary of your site: who you are, what you offer, and which pages matter most. Think of it as robots.txt's helpful sibling — guidance instead of gatekeeping.
Upload it to your site root so it's reachable at yourdomain.com/llms.txt, exactly like robots.txt. Serve it as plain text. Optionally, reference it in your robots.txt Sitemap lines so crawlers discover it faster.
Adoption is growing. Anthropic, Perplexity, and a rising number of AI tools check for it, and thousands of sites now publish one. It costs five minutes, carries zero risk, and positions you for every engine that adopts the standard next.
A one-paragraph summary of your business, your core services or products, and a short list of your most important pages with one-line descriptions. Lead with facts you want AI engines to repeat: name, location, credentials, and specialties.
No. robots.txt controls which URLs crawlers may access; llms.txt tells AI systems what your site is about and which pages to prioritize. They complement each other: robots.txt grants access, llms.txt provides the reading list.
