Build an llms.txt file that tells AI tools what your site is and where the key pages are
Enter your site name, a one line summary, optional context and your key pages. The tool writes a Markdown llms.txt file, checks its structure and lets you download it.
An llms.txt file is a plain Markdown file at the root of your site. It gives a language model a short summary of the site and a curated list of links with a description for each. The idea comes from the llmstxt.org proposal. It is not an official web standard, and I could not confirm that any major AI service reads it. Google says you do not need new AI text files to appear in its AI features, and its John Mueller has said no AI system currently uses llms.txt. Treat it as a low cost, optional file.
The generator asks for what the file needs: the site or brand name, a one line summary of what the site is and who it serves, the site URL to complete relative links and an optional block of extra context. You list key pages one per line as title, URL and short description, grouped under headings that start with two hash marks. A second box takes optional pages that an AI tool can skip when context is short.
The tool then writes the file, counts links and sections, shows the file size and checks the structure. You download it as llms.txt and upload it to your site root.
- Site name and one line summary
- Key pages grouped by section
- Optional pages section
- Structure check
- Download llms.txt
- Free, no signup
Build the file in four steps
The file updates as you type.
- Load an example or start blank. Choose the local service business or the software docs site.
- Describe the site. Name, a one line summary, the site URL and any extra context an AI reader should know, such as where you do not work.
- List key pages. One per line as title, URL and short description, with a heading line starting with two hash marks for each group. Put lower value pages in the optional box.
- Download and upload. Upload llms.txt to your site root so it opens at yourdomain.com/llms.txt.
| Field | What it does |
|---|---|
| Site or brand name | Becomes the first heading of the file. |
| One line summary | Becomes the quote line under the heading. |
| Site URL | Completes relative links such as /about/. |
| Extra context | Optional notes for AI readers. |
| Key pages | Title, URL and description, grouped under headings. |
| Optional pages | Links an AI tool can skip when context is short. |
One real run on the local service example
I loaded the local service business example: Acme Plumbing, a one line summary about plumbing in Ahmedabad, a placeholder site URL and a short context note about the business history, pricing and service area. It listed two groups, Services and Company, plus one optional page.
The tool built a file with 3 sections and 5 links, 0.6 KB in size, and reported no problems, noting that the file follows the llmstxt.org structure. Relative links such as /drain-cleaning/ were completed with the site URL.
| Field | Value |
|---|---|
| Name | Acme Plumbing |
| Groups | Services, Company |
| Optional page | Blog |
| Site URL | Placeholder example domain |
| Item | Result |
|---|---|
| Sections | 3 |
| Links | 5 |
| File size | 0.6 KB |
| Check | No problems found |
| Upload path | /llms.txt in the site root |
What the generated file looks like
Structure taken from the real run.
Heading
A single first level heading with your site name.
Summary
A quote line with your one line summary.
Context
A short paragraph with your extra context, such as pricing location or service area.
Sections
Second level headings, such as Services and Company, each with a bullet list of links.
Link lines
Each is a Markdown link followed by a colon and a short description.
Optional section
Links an AI tool can skip when context is short.
What llms.txt does and does not do
Set expectations before you spend time on it.
It is a proposal, not a standard
The structure comes from llmstxt.org. I could not confirm that any major AI service reads the file, and Google says it does not need one for its AI features, so do not expect a ranking or citation boost.
It is not robots.txt
It does not allow or block crawlers. Use the robots.txt generator for crawl rules.
It is only as good as your list
A short, curated list of useful pages beats a dump of every URL.
You upload it yourself
The tool does not install the file. Put it in your site root.
Keep it current
If you move or delete pages, update the file so it does not point to dead links.
The check covers structure only
It confirms the layout. It does not test that your links work or that the descriptions are accurate.
Where it helps
Local and service businesses
Keep a clear summary, service list and service area in one plain file.
Software and docs sites
List key docs pages in one curated file.
Publishers and agencies
Offer a hand picked guide to the best pages.
SEO consultants
Add a low cost file to a site while they wait for evidence on its value.
llms.txt, robots.txt and a sitemap
They do different jobs.
| File | Job | Audience |
|---|---|---|
| llms.txt | A curated summary and link list in Markdown | AI tools, as proposed |
| robots.txt | Crawl rules for allowed and blocked paths | Crawlers |
| XML sitemap | A full list of URLs for indexing | Search engines |
How this page was checked
Where I use it
I follow AI search changes and I build tools only for files I can explain.
Run on a real sample
The 3 sections, 5 links and 0.6 KB file come from one live run on the plumbing example.
Honest about value
I could not confirm that major AI services read llms.txt, and this page says so instead of promising results.
LLMs.txt Generator FAQ
Quick answers on what llms.txt is and what it does not do.
What is an llms.txt file?
A Markdown file at the root of your site with a summary and a curated list of links and descriptions, proposed so language models can understand the site quickly.
What does the llms.txt generator do?
It builds the file from your site name, summary, context and key pages, checks the structure and lets you download it.
Is it free?
Yes. There is no signup.
Is llms.txt an official standard?
No. It is a proposal published at llmstxt.org.
Do AI tools read it?
I could not confirm that any major AI service does. Treat it as an optional file with no promised effect.
Where do I upload llms.txt?
To your site root so it opens at yourdomain.com/llms.txt.
How do I list my pages?
One per line as title, URL and short description. Start a group with a heading line using two hash marks.
What goes in the optional pages box?
Lower value pages that an AI tool can skip when context is short, such as a blog index.
Do I need to write full URLs?
No. Relative links such as /about/ are completed with the site URL you enter.
How long should the file be?
Short. The sample was 0.6 KB with 5 links. A curated list is more useful than every URL.
What does the structure check test?
Layout only. The sample reported no problems and noted the file follows the llmstxt.org structure. It does not test that links work.
Is it the same as robots.txt?
No. Robots.txt gives crawl rules. llms.txt is a content summary. Neither replaces the other.
Can it block AI crawlers?
No. Use robots.txt rules or server controls for that, and note that compliance with them is up to each crawler.
Does it help my rankings?
I cannot confirm that. Google has not announced support for llms.txt as far as I know, so do not count on a ranking effect.
Does the tool store what I type?
The tool runs in your browser. I read this page’s code for network calls and found none that send your input to my server. If the page has a Share link, it puts your input in the web address after the # sign, and Save keeps it in this browser only, so do not share a link that holds private text. Normal site analytics can still record the page visit.
What should I use next?
Set crawl rules with the robots generator and list your pages with the sitemap generator.
