Free llms.txt Generator & Analyzer

llms.txt is a proposed standard (like robots.txt) — a markdown file at your website's root (yoursite.com/llms.txt) that gives AI models a structured summary of your site: what it is, its key pages, and how to describe it. It helps ChatGPT, Gemini, Perplexity, and other AI engines understand and cite your brand accurately.

It's one of the fastest AI-visibility wins available. About 95% of websites don't have one, so adding it puts you ahead of nearly all competitors. It takes minutes, costs nothing, and directly addresses the #1 reason AI misdescribes brands: it can't find a clean summary of what you do.

Upload it to your website's root directory so it loads at yoursite.com/llms.txt — the same place robots.txt and sitemap.xml live. Most hosts let you upload via FTP, a file manager, or your CMS. Our generator includes 30-second install instructions.

llms.txt is a concise summary (brand, key pages, contact) — what our generator creates. llms-full.txt is an optional companion containing your site's full documentation in one file. Start with llms.txt; most sites never need the full version.

No single file guarantees citations — AI visibility also needs good content, reviews, and directory presence. But llms.txt removes a common blocker: when a model looks for authoritative info about you, it finds a clean source instead of guessing. Pair it with our free AI visibility checker to measure the difference.

No. The generator runs entirely in your browser — your brand name, URLs, and descriptions never leave your device. There's nothing to sign up for and nothing stored on our servers.

Update it whenever your key pages, positioning, or contact details change — a quick refresh every few months is plenty for most sites. If you launch a major new product or rebrand, regenerate it right away.

robots.txt tells crawlers which pages they may or may not access; llms.txt tells AI models what your site is and which pages matter most. They sit side by side in your site root and do different jobs — you want both.

No. No AI vendor promises citations for having the file; it simply removes the guesswork when a model summarises or recommends your site, so descriptions are accurate instead of improvised. Treat it as cheap insurance, not a ranking trick.

llms-full.txt is the optional companion file that contains the full text of your key pages in one markdown document, for models that want everything at once. Most small sites only need llms.txt; llms-full.txt suits documentation-heavy sites.

Whenever your important pages change — a new product, a moved guide, a rebrand. For most sites a quick review every month or two keeps the file honest, and regenerating takes minutes.
