Why the File Is Easy to Make and Easy to Get Wrong

llms.txt is simple by design. It is a plain-text file, written in a light markdown format, that sits at your site root and hands AI models a summary of what your site is and where the important pages live. Anyone can create one, and our free tool will draft a good one for you in a minute. The format is not the hard part.

The hard part is judgment. The whole value of the file is curation, and the instinct most people follow is the opposite one: list everything, just in case. A file that includes every page you own tells a model nothing about priority, which defeats the purpose. A strong file is short, ruthless about what earns a spot, and written with descriptions a model can lift verbatim. That is editorial work, and it is what we do.

Then there is the part everyone forgets: maintenance. The file that was accurate at launch quietly rots as your site grows. We keep it honest, and we pair it with the deeper accessibility work, because a perfect map is useless if the crawlers that read it are blocked. The full context lives in our complete llms.txt guide.

What We Do

The Implementation, Done Properly

Curate, do not dump

The single most common llms.txt mistake is listing every URL you own. That tells a model nothing about what matters. We audit your site, identify the pages that genuinely represent your value, and select only those. A strong file is short and deliberate, and the curation is the part a generator cannot do for you.

Write descriptions a model can use

Each entry gets a real description, not a slug. A model reading our llms.txt on this site learns what each page covers and why it matters, phrased so it can lift the summary directly. We write those descriptions for your pages the way we write them for our own, because the wording is what turns a link list into a usable map.

Add the long companion when it earns its place

For sites with real depth, a short llms.txt pairs with an llms-full.txt that expands each entry. We decide whether your site warrants the longer file, then build both to spec, hosted correctly at your root and serving as plain text, so the models that read them get exactly what they need.

Keep it current as the site grows

An llms.txt frozen at launch describes last quarter's site. We fold updates into your release process so new priority pages get added and retired ones get removed, keeping the map honest. Freshness is a signal in its own right, and a maintained file beats a perfect file that went stale.

FAQ

llms.txt Questions

What is llms.txt and do I really need a service for it?+
llms.txt is a plain-text file at your site root that gives AI models a curated summary of your most important content. You do not strictly need a service, and our free generator will build you a solid starting file in a minute. The service exists for the part the generator cannot do: deciding what to include, writing descriptions worth reading, and keeping it current. For a small site, DIY is fine; for a large or high-stakes one, curation is the whole value.
How is this different from your free generator?+
The free tool reads your site and assembles a spec-correct file from your title, description, and sitemap. That is a great starting point. The service is the human layer on top: trimming to the pages that actually matter, rewriting the descriptions for clarity, deciding on llms-full.txt, and maintaining it over time. Think of the tool as the draft and the service as the edit.
Will llms.txt make AI cite my brand?+
By itself, no. llms.txt is a map, not a magnet. It helps the models that fetch pages on demand find your best content quickly, which supports citation, but the content still has to be worth citing and the crawlers still have to be able to reach it. We treat llms.txt as one piece of a larger visibility program, not a standalone fix.
Which AI tools actually read llms.txt?+
Adoption is real but uneven, and it is growing. Notably, Google added an llms.txt check to Lighthouse's agentic browsing audit in 2026, which moved the file from optional to expected for sites that care about being agent-ready. We keep track of which systems use it and implement to the current spec rather than a dated blog post.
Can you maintain it on an ongoing basis?+
Yes. The most common failure mode for llms.txt is neglect: a file that was accurate at launch and describes a different site a year later. We can own it as part of ongoing work, updating it whenever your important pages change, so the map the models read always matches the site they land on.
