- 2
Run the check
We fetch from our server (not your browser), follow a few redirects, and reject private hosts.
- 3
Read the file
Found, missing, or a web page pretending to be text. Copy the preview if you want to compare drafts.
FAQ
What is llms.txt?
A plain-text (usually Markdown) file at the site root that tells AI agents what the product is and which URLs to read first. Same job as robots.txt, for models.
Does a missing file mean bad SEO?
No. Most sites still don’t ship one. It helps crawlers; it is not a Google ranking factor by itself.
Can you generate the file for me?
Not in this checker. We only fetch. Tools that write schema or llms.txt are linked below when we verified that capability on the vendor site.
