How it works
1
Check your site
Type your website. We tell you if you have an llms.txt and exactly what to fix, in plain English.
2
Create or fix it
No file? Our generator writes one for you. On WordPress, popular SEO plugins can do it automatically; on Shopify, a file upload and a redirect does it.

What to fix
-
Line 14 looks like a link but it isn't written in the usual format, so AI tools may not read it as one.
How to fix: Check the brackets and the address. The format is - [Page name](https://yoursite.com/page): note.
Why list your llms.txt?
Publishing the file is step one. Listing it means it's checked, kept working and easy to find.
- Hear when it breaks. A theme update, a plugin change or a site move can replace your llms.txt with an error page, and you'd never notice. Paid plans check it and email you.
- Know it works. A score and plain-English fixes.
- Keep a record. On paid plans, every version, with what changed.
- Get found. A listing in your industry that links to you.
Publishing the file is step one. Listing it means someone checks that it actually works, tells you in plain English when something is wrong, and keeps a public record of it. You get a validated file, a listing page that links to your site, and (on paid plans) an alert the moment the file breaks or changes.
We can't promise that, and nobody honestly can: each AI company decides what it reads. What a listing does is make your llms.txt easier to discover. It sits on a public, well-structured page that people, search engines and AI crawlers can reach, next to a link to your site. The bigger win is knowing your file is correct, because a broken file helps no one.
Every check scores your file out of 100 against the llms.txt proposal and lists each problem with exactly what to change. Most files we see have at least one issue: a missing title, links that point to the wrong place, or a web page served where the text file should be. Fixing those is the difference between a file AI tools can use and one they skip.
Files break quietly. A theme update, a plugin change, a site migration or a CDN rule can replace your llms.txt with an error page, and you'd never notice. Paid plans check it every month or every night, keep each version so you can see what changed, and email you when it disappears or breaks. Nightly also emails you exactly what changed.
It's a dated record of what your llms.txt said and when. Teams use it to see who changed what, to roll back a bad edit, and to prove what they told AI tools at a point in time. Paid plans show a line-by-line comparison of every change, and Nightly also emails it to you.
