Create a valid llms.txt file that helps AI engines understand your site

An llms.txt generator is a free online tool that builds a valid llms.txt file for your website. llms.txt is a proposed standard, placed at the root of a domain, that gives AI engines like ChatGPT, Claude, Perplexity and Gemini a clean, curated summary of what your site is about and which pages matter most. Fill in your site name, a one sentence summary and your key pages grouped into sections, and the tool writes the file in the exact expected format, ready to copy or download. Everything runs in your browser, free and with no registration.

Your site Site or project name * One sentence summary * Extra details (optional)

Sections and links

Group your key pages under section names such as Docs, Guides or Policies. Name a section "Optional" for secondary links AI engines may skip.

Tips for a good llms.txt

Keep the summary short and factual: one sentence that says what the site is and who it is for.
Curate, do not dump. List the pages that best explain your product, not every URL on the site.
Use clear link descriptions. They tell the AI what each page answers.
Place secondary links under an Optional section, so AI engines with a small context window can skip them.

FAQ about the llms.txt generator

What is llms.txt?

llms.txt is a proposed web standard, similar in spirit to robots.txt or sitemap.xml, that lives at the root of your domain. It is a Markdown file that tells AI engines what your site is about and which pages contain the information that matters, in a format that is easy for language models to read.

Where do I put the llms.txt file?

Upload it to the root of your domain, so it is reachable at yoursite.com/llms.txt. On WordPress you can place the file in the root folder via FTP or your hosting file manager. Some SEO plugins can also generate and serve it.

What is the difference between llms.txt and robots.txt?

robots.txt tells crawlers what they may not access. llms.txt does the opposite: it tells AI engines what they should read, with a curated summary and your most important links. The two files complement each other and live side by side in the site root.

Do AI engines actually use llms.txt?

llms.txt is an emerging standard. Adoption is growing across documentation platforms and AI tools, and because the file is tiny and harmless, adding one is a low effort step that prepares your site for AI search while competitors are still ignoring it.

What is llms-full.txt?

llms-full.txt is a companion file that contains the full text content of your key pages in one Markdown document, for AI engines that want everything at once. Most sites start with the standard llms.txt index, which is what this tool generates.

Is the llms.txt generator free?

Yes. The generator is completely free, with no registration and no limit. The file is built in your browser and nothing you type is sent to a server, saved or logged.
