AI Search

llms.txt tells AI engines what your store actually sells.

llms.txt is a plain-text file at your domain root that gives AI engines a direct, structured summary of your site — the same idea as robots.txt, but written for language models instead of crawlers. Once your store is connected, Cassian™ checks whether you have one, and can generate one from your catalog if you don’t.

What Cassian™ actually checks

Specific checks, not a vague promise.

Once your store is connected, Cassian™ checks whether it has an llms.txt file at your domain root, with a guard against a styled “not found” page pretending to be one.

FAQ

Common questions about AI search

Does Cassian™ validate my llms.txt file?
Cassian™ checks whether the file exists — not whether its contents are valid against a spec, since there isn’t yet an agreed one to validate against.
Can Cassian™ create an llms.txt file for me?
Yes. Once your store is connected — Analyst tier and above — Cassian™ generates an llms.txt file from your live catalog: store name, categories, and featured products, alongside your AI product feeds. That hosted file refreshes daily as your catalog changes. You place a copy at your domain root yourself, and re-deploy it when you want the latest version live.
