An llms.txt file tells AI engines what your site is about and which pages matter, the way robots.txt does for search crawlers. Fill in the basics and get a clean, correct llms.txt to upload to your site's root.
llms.txt is one piece. We engineer schema, answer-first content, and crawler access so AI engines actually cite you. Free audit available.

A clear title and one-line summary of your business, then a curated list of your key pages, each with a short description, services, service areas, contact. It’s plain text in a light Markdown format, easy for both humans and AI to read. This tool builds a correct one from a few inputs.
AI engines are better at understanding and citing you when you hand them a clean, structured overview instead of making them guess from your raw HTML. llms.txt is quick to add, costs nothing, and signals that your site is built for the AI era, exactly the kind of detail that separates AI-ready sites from the rest.
Five fields, and the text writes itself as you type. Your business name becomes the top heading. The one-line summary becomes the quoted line directly beneath it. Each row you enter in the key pages box, written as a title, then a path, then a short description separated by pipe characters, becomes a link in a Key pages list. The generator tidies your web address along the way, adding https:// if you left it off, trimming a trailing slash, and joining each relative path onto the domain so every link in the finished file is absolute. An optional contact line is appended as its own section. Copy the result, save it as llms.txt, and put it at the root of your domain.
All of that happens in the page itself. Nothing is uploaded, no account is created, and the tool never fetches your website. That last point matters more than it sounds. It does not crawl your site to discover your pages, it does not check that the paths you typed resolve, and it has no way to know whether your summary is accurate. A mistyped path becomes a dead link inside the file, and a stale description sits there until you edit it by hand.
Be equally clear-eyed about the format. An llms.txt file is a proposed convention rather than a settled standard, support for it differs between AI engines, and publishing one is not a ranking lever or a promise of anything. It is cheap, it takes a few minutes, and it hands an engine a clean map of your site if it goes looking for one. It also does nothing at all if your host or CDN is blocking AI crawlers, which happens more often than owners realize, so check that before you bother.

No. It never requests a single page from your site. It takes the titles, paths, and descriptions you type and turns them into links against your domain, so a typo becomes a broken link in the published file. Open each finished URL in a browser once before you upload, and delete any row you cannot verify.
There is no guarantee, and anyone who tells you otherwise is selling something. Engines vary in whether they look for the file at all. It is a small, honest piece of housekeeping that makes your site easier to understand, not a mechanism that produces results on a schedule.
