¿Qué es llms.txt?
llms.txt es un archivo en Markdown ubicado en la raíz de tu sitio que proporciona a los modelos de lenguaje de IA un mapa seleccionado de tu contenido más importante.
We generate it to the official llmstxt.org specification:
An H1 with your site name — the primary title
A cita summarising the site directly beneath it
H2 sections holding link lists: - [Página](url): descripción
A final Opcional section for secondary pages
Guía de implementación
1. Descarga el archivo: Save as llms.txt
2. Súbelo a la raíz del sitio: Place the file at tudominio.com/llms.txt
3. Verifica el acceso: Open tudominio.com/llms.txt in browser to confirm accessibility
4. Los modelos de IA descubren automáticamente: Crawlers like GPTBot, ClaudeBot, and Gemini read this file for search context.
An llms.txt generator is a tool that writes the llms.txt file for your site: a Markdown file at yourdomain.com/llms.txt that gives large language models a short map of your most useful pages. This generator crawls your website from its homepage and writes a file in the llmstxt.org format, with one H1, a summary and sections of annotated links. Each file uses 20 credits.
What the llms.txt generator writes
A Markdown file in the exact structure the specification asks for, built from the pages it finds on your site.
One H1 with your site name
The file opens with a single H1, as the spec requires.
A blockquote summary
One short description of what the site is, directly under the H1. Add your own description to steer it.
H2 sections of links
Your key pages grouped under H2 headings, each as - [Page name](url): description.
An Optional section, last
Secondary pages such as contact and legal go in the section the spec says may be skipped.
Copy or download
Copy the Markdown or download llms.txt, ready to upload to the root of your domain.
Run the live file through the free checker to confirm it parses.
How to create an llms.txt file
Four steps from your homepage address to a live file.
Sign in
The generator crawls your site on our servers, so it needs an AI Rank Lab account. Each generation uses 20 credits.
Enter your website URL
Paste your homepage address. Optionally add a sentence describing the site to steer the summary.
Generate and review
The tool crawls your pages and writes the file. Read it and edit any description you would phrase differently.
Upload to your domain root
Download llms.txt and place it so it loads at https://yourdomain.com/llms.txt, then check it with the llms.txt checker.
How to read the generated llms.txt
The file is plain Markdown with only two heading levels, so it reads the same for people and for programs.
# Site name
The single H1 at the top. It is the only part the specification requires.
> Summary
One blockquote paragraph that says what the site is and who it serves. Edit it if it doesn't sound like you.
## Sections
H2 headings that group your pages, such as Docs, Guides, Products or Blog.
- [Page](url): note
One link per line, with a short note on what the page covers. Use absolute URLs.
## Optional
Pages a model may skip when it needs a shorter context, such as contact or legal pages. It always comes last.
What llms.txt is for
llms.txt is a proposed standard, published at llmstxt.org in 2024, for a Markdown file at the root of a website. Where robots.txt tells crawlers what they may fetch, llms.txt tells language models what the site is and which pages are worth reading, with a line of context for each.
The file is small on purpose. Models and AI agents that look for it get a curated index instead of navigation menus, scripts and boilerplate.
Does llms.txt help AI visibility?
Not on its own, and not yet in a way anyone can measure reliably. Major AI companies have not committed to reading llms.txt when they answer questions, and Google has said it doesn't use it for Search. It is cheap to add, it helps AI coding tools and agents that do read it, and it forces a useful exercise: deciding which pages best explain your business.
What moves AI visibility is the rest of the site: pages that answer real questions clearly, that crawlers can reach, and that other sites cite. To see whether AI engines mention you today, track it directly.
llms.txt vs llms-full.txt
llms.txt is an index of links. llms-full.txt is a companion convention that holds the full text of those pages in one file, so a model doesn't have to fetch each link. Documentation sites often publish both. This generator writes llms.txt.

Every file follows the official specification at llmstxt.org.
What this llms.txt generator doesn't do
It needs a signed-in account, and each generation uses 20 credits. New accounts start with 100 free credits.
It works from the pages it can reach by crawling from your homepage. Pages that nothing links to won't be included.
It doesn't write llms-full.txt or the .md versions of each page that the specification also suggests.
It doesn't upload the file. Place it at your domain root, then validate it with the free llms.txt checker.
It can't make AI engines read or cite your site; llms.txt is a voluntary convention.
Support is informal. Some AI coding assistants, agents and documentation tools fetch llms.txt when they find it, but the major AI search engines have not committed to using it, and Google has said it does not use llms.txt for Search. Treat it as a low-cost addition, not a ranking or citation lever.
Does llms.txt improve AI citations?
There is no reliable evidence that it does on its own. AI engines cite pages they can crawl and that answer the question well. llms.txt can help tools that read it understand your site faster, which is why it's worth the few minutes it takes, but measure citations directly rather than assuming a lift.
What is llms.txt?
llms.txt is a Markdown file placed at your domain root that gives large language models structured guidance about your website. It follows the llmstxt.org format: an H1 site name, a blockquote summary, and H2 sections linking to your key pages with descriptions. It is similar in purpose to robots.txt but designed to help AI understand and cite your content rather than control crawler access.
What is the difference between llms.txt and robots.txt?
robots.txt controls which pages crawlers may access. llms.txt provides context — telling AI models what your content is about and which pages to prioritise. They are complementary: robots.txt manages access permissions; llms.txt provides content guidance and citation preferences for AI engines.
What is llms-full.txt and do I need it?
llms-full.txt is an optional extended version of llms.txt that includes the full Markdown content of each linked page, giving LLMs a complete picture without needing to crawl individual URLs. It is larger and more complex to maintain, but useful for sites with documentation or detailed technical content where depth matters.
What content should I include in my llms.txt?
Include your site name, a clear one-sentence summary, and a curated list of your most important pages with brief descriptions. Prioritise pillar content, key product pages, and documentation. Omit thin, duplicate, or draft pages — the goal is a high-quality map, not a complete index.
Does llms.txt affect my Google rankings?
No. Google has confirmed it does not use llms.txt, so it has no direct effect on traditional Google rankings. Its value is AI visibility — helping engines like Claude and Perplexity understand and accurately cite your content. For Google, focus on technical SEO, structured data, and E-E-A-T content signals.
Can AI Rank Lab help beyond llms.txt?
Yes. AI Rank Lab offers a full AEO and GEO toolkit to track and improve your visibility across ChatGPT, Gemini, Perplexity, and Claude, including a free AEO and GEO audit that benchmarks how AI engines currently perceive your brand and what to fix first.
Does this generator follow the official llms.txt specification?
Yes. Every file this tool produces is generated and then validated against the official specification published at https://llmstxt.org/ — exactly one H1, a blockquote summary directly beneath it, only H1 and H2 headings, link-list items inside every H2 section, and the special Optional section placed last.
What does the Optional section mean?
The specification gives a section titled exactly "Optional" special meaning: the URLs listed there may be skipped when a shorter context is needed. Use it for secondary pages such as contact, legal and policy pages. It must be the last section in the file.
Is the llms.txt generator paid?
Our llms.txt generator uses AI Rank Lab and requires 20 credits per generation with an active AI Rank Lab account.
How do I implement llms.txt?
Download the generated llms.txt file and upload it to your website's root directory so it is served at yourdomain.com/llms.txt, the location the specification requires. The spec also recommends publishing a markdown version of each HTML page at the same URL with .md appended.
Is there a free llms.txt generator?
Signing up gives 100 free credits with no card, enough for five llms.txt files at 20 credits each. To check a file you already have, the llms.txt checker is free and needs no account.
