Configure your llms.txt

The form loads with example placeholders. Replace every name, description, and URL with accurate information about your own site. Optional scanning discovers same-origin pages via HTTP fetch; it does not run JavaScript or invent copy for you.

Scan a website

Optional: discover same-origin pages via the homepage, robots.txt, and sitemaps. Scanning uses WebFixer’s secure server fetcher with strict limits. It does not run JavaScript or follow external links.

Site overview

The H1 is your site or project name. The optional blockquote is a short summary (Markdown blockquote syntax in the output).

Resource sections

Each section becomes an H2 heading followed by Markdown links. Use absolute http(s) URLs only; paths and query strings are preserved.

Optional resources

Use this for lower-priority links you still want to list, clearly separated from primary sections.

Live preview

Structure: one H1, optional blockquote, H2 sections, then - [label](url): description lines. Copy or download when ready to upload as /llms.txt on your site.

llms.txt is a proposed convention for pointing AI tools at helpful resources. It is not a formal web standard, and publishing a file does not guarantee how models crawl, cite, or rank your content.

Complete guide to llms.txt

llms.txt is a proposed convention: a Markdown file at /llms.txt that summarises your site and links to key resources for humans and AI tools. It is not a formal web standard, not a Google ranking signal, and not a guarantee of AI citations or traffic.

Typical structure

  • One H1 line: site or project name.
  • Optional blockquote: short summary.
  • H2 sections with Markdown links: - [Label](https://example.com/page): description
  • Optional trailing section for lower-priority links.

Example (fictional)

# Example Docs

> Public documentation and API reference for Example Ltd.

## Guides

- [Getting started](https://docs.example.com/start): Setup for new projects.
- [API reference](https://docs.example.com/api): HTTP endpoints and auth.

## Optional resources

- [Status page](https://status.example.com/): Uptime history.

Manual editor

Replace placeholder text with real names, descriptions and absolute URLs. The preview updates as you type. Only http:// and https:// links are accepted; unsafe schemes are rejected.

Optional website scanner

The scanner calls WebFixer's server API to fetch same-origin pages. It:

  • Starts from the homepage URL you provide (default max 25 pages, hard cap 40).
  • Reads robots.txt for disallow rules and may fetch up to 6 sitemap documents (with URL limits).
  • Does not execute JavaScript, follow external links, or fetch arbitrary off-site URLs.
  • Returns discovered titles and URLs you can apply to the editor; it does not auto-publish llms.txt for you.

Publishing and validation

Upload the file as plain Markdown/text at https://yourdomain/llms.txt without redirecting to login. Run the SEO audit to see whether the file is reachable, looks like text, or redirects away (for example to a sign-in page).

How llms.txt differs from other files

FileRole
robots.txtCrawl hints for bots; machine-oriented directives.
XML sitemapURL discovery list for search engines.
llms.txtHuman-readable summary and curated links for documentation-style discovery.
Normal web pagesAuthoritative content; llms.txt should link to them, not replace them.

Common mistakes

  • Listing URLs that do not exist or return errors.
  • Using relative links (not supported in the generator output).
  • Expecting llms.txt to block or allow crawlers (use robots.txt).
  • Claiming ranking or AI performance benefits in marketing copy.

Limitations

No guarantee any AI product reads llms.txt. Scanner coverage is limited by robots rules, sitemap size caps, and the page fetch limit. Generator and scan do not verify that linked pages stay up to date.

llms.txt FAQ

Is llms.txt required for SEO? No. Treat it as optional documentation for curated discovery.
Why did the scanner miss pages? JavaScript-rendered navigation, robots disallow, off-site URLs, or the max page limit can exclude pages.
Can I run the scanner on localhost? The scanner targets public URLs WebFixer can fetch securely; local-only hosts are not supported.

Before you publish

Accurate links and descriptions matter more than length. Pair llms.txt with robots.txt and sitemaps for crawl discovery.

Write for humans and tools

Use plain language descriptions you stand behind. Do not claim pages exist unless the URL is real and under your control.

Keep URLs absolute

This generator accepts only http(s) URLs. Relative links and unsafe schemes such as javascript: are rejected.
