llms.txt Generator: Create Your File in 60 Seconds
Free tool by AEO GEO Labsby the AEO GEO Labs team4 min read
An llms.txt generator builds a first draft of the markdown file that sits at yourdomain.com/llms.txt and points AI agents to your most useful pages. Ours reads your sitemap, picks the shallowest URLs, groups them into sections and writes the file for you to edit. Open the free llms.txt generator, paste your domain, and you have a draft in under a minute.
New to the file itself? Start with our guide to what llms.txt is and does.
How the llms.txt generator works, in four steps
You generate llms.txt by turning your key pages into a short, structured markdown file. With the tool, that takes four steps:
- Open the llms.txt generator and choose the Generate tab.
- Enter your domain. The tool reads the sitemaps listed in your robots.txt, or tries
/sitemap.xmland/sitemap_index.xml. With no sitemap, it falls back to the links on your homepage. - Review the draft. It takes up to 200 URLs, ranks them by how shallow they are (
/pricingbefore/blog/2023/some-post), fetches the title and meta description of the top 30, and groups pages into H2 sections by their first path segment. Legal and careers pages go under## Optional. - Edit, download, and upload the file to your site root so it loads at
https://yourdomain.com/llms.txt. In most frameworks that means thepublicorstaticfolder.
Then run the Validate tab against your live domain to confirm the server returns plain text, not HTML.
What a good generated file looks like
A good llms.txt file follows the format published at llmstxt.org: an H1 with your site name (the only required part), a blockquote summary, optional notes, then H2 sections of links. The shape to aim for:
# Ledgerly
> Ledgerly is payroll software for remote teams in 30 countries.

## Optional

Every link line uses - [Title](URL): note. The note tells an agent whether the page is worth fetching, so make it specific.
How to read the validator results
The validator checks your live file line by line and pairs each problem with a fix. The common results:
| Result | What it means | What to do |
|---|---|---|
| No llms.txt | The URL returned an error or an empty body | Generate one and upload it to the root |
| /llms.txt serves an HTML page | A catch-all route or soft 404 answered | Serve a static file instead |
| Served as text/html | Wrong content type | Use text/plain or text/markdown |
| Doesn't start with an H1 | Missing the one required line | Make line one # Your Company |
| No summary blockquote | Optional, but useful | Add one > line saying what you do |
It also requests up to 15 linked URLs to catch dead ones.
Edit before you upload
A generated llms.txt is a draft. Sitemaps list everything; llms.txt should list what answers real questions. Three edits matter most:
- Cut hard. Twenty well-described pages beat 200 bare links.
- Rewrite the notes. Say what each page answers, in plain words.
- Fix the summary. One sentence: who you are, what you sell, who for.

Be honest about what it does
As of October 2026, no major AI search engine says it uses llms.txt to pick citations, and Google's AI features guidance says no AI text files are needed. It mainly helps agents reading documentation. Publish it, then put real effort into crawler access with our guide to robots.txt for AI crawlers.
Frequently asked questions
Is the llms.txt generator free?
Yes. The generator and validator are free and need no sign-up. Enter a domain, get a draft built from your sitemap, edit it in the browser and download the file. The validator checks any live llms.txt against the llmstxt.org format and samples its links.
Where do I upload the generated llms.txt file?
Upload it to the root of your domain so it loads at https://yourdomain.com/llms.txt. Serve it as plain text or markdown. On WordPress, a plugin or your host's file manager works. On Next.js, Astro or similar frameworks, put it in the public or static folder. Then run the validator to confirm it returns text, not HTML.
Does a generated llms.txt help me rank in ChatGPT?
There's no public evidence that it does as of October 2026. No major AI search engine has confirmed using llms.txt as a citation signal, and Google says no special AI files are needed for its AI features. The file helps agents find your best pages quickly. Rankings and citations still come from crawlable, useful, well-cited content.
Should I also create llms-full.txt?
Only if you run documentation or an API. llms-full.txt is a convention, not part of the llmstxt.org spec: one file holding the full text of your key pages so a tool can load everything in one request. Docs sites benefit. Most marketing sites only need the short llms.txt index, and a huge full file is rarely read in full.
How often should I regenerate llms.txt?
Edit it whenever you add, remove or rename an important page, and review it at least once a quarter. Dead links make the file less useful to agents. Run the validator after each change: it requests a sample of the linked URLs and flags any that fail.
