llms.txt Checker
Enter your URL to see if your site has a valid llms.txt file for AI tools, and whether it is really yours or Shopify's generic default. Plus a bonus AI visibility score.
What is llms.txt?
llms.txt is a simple text file you place at the root of your website. It gives AI
tools a short, clean summary of your most important pages, written in plain Markdown. Think of it
as a friendly map for assistants like ChatGPT and Perplexity — not for humans, but easy for a
person to read too.
Here is what a good llms.txt looks like for a small store:
# Your Store
> Handmade ceramic mugs and tableware, shipped worldwide.
## Products
- [Ceramic Mug](https://yourstore.com/products/ceramic-mug): 350ml stoneware mug, $28
- [Dinner Plate Set](https://yourstore.com/products/plate-set): set of 4, $64
## Policies
- [Shipping](https://yourstore.com/policies/shipping-policy)
- [Returns](https://yourstore.com/policies/refund-policy)
The first line is your name. The > line is a one-sentence summary. Each heading
groups a few links with a short note. Keep it short, keep it current, and only list pages you want
AI to read.
How to add or replace llms.txt on Shopify
Every Shopify store now serves an llms.txt and agents.md by default.
It is the same file on every store: generic Shopify platform and Shop-app instructions plus
links to your policy pages, with nothing written about your products or brand.
This checker tells you if that default is all you have.
To replace it, you can publish your own file through your theme and edit it by hand every time your catalog changes, or use an app that writes it from your catalog and keeps it current. Our full guide to llms.txt for Shopify walks through both.
One honest note: llms.txt is still an emerging standard. Most AI crawlers do not read it yet, so its impact today is small. Add it as cheap insurance — but put your real effort into crawler access and structured data first.
Generic llms.txt? Make it about your store.
Kedra AI Index replaces Shopify's generic llms.txt and agents.md with files written about your products, collections, policies, shipping and returns, and keeps them in sync as your catalog changes. No theme code, no manual updates.
llms.txt, answered
What does this llms.txt checker do?
It fetches your site and looks for a file at /llms.txt. If the file exists, the checker tells you whether it is written for your site or is Shopify's generic default, and links you straight to it. If there is no file, it tells you and shows how to add one. You also get a bonus AI visibility score.
Where should llms.txt be located?
It belongs at the root of your domain, exactly at yourstore.com/llms.txt — the same place robots.txt lives. AI tools that support the standard look for it there and nowhere else. If you put it in a subfolder, it will not be found. This checker tests the correct root location for you.
What makes a good llms.txt file?
A good llms.txt is short and plain. It starts with your site name and a one-line summary, then uses simple headings with links to your key pages — top products, collections, and policies. Keep it in Markdown, keep it current, and only link pages you actually want AI to read. See the annotated example above.
Is llms.txt required, and does it help?
It is not required, and it is an emerging standard — most AI crawlers do not fetch it yet, so its proven impact today is small. But it is trivial to add and acts as cheap insurance as AI tools adopt it. Do not rely on it alone; crawler access and structured data matter far more right now.
How do I create an llms.txt for Shopify?
Shopify now serves a generic llms.txt and agents.md on every store. They describe the Shopify platform and the Shop app, not your products. To replace them you publish your own through your theme, or use an app. Kedra AI Index replaces both with files written about your products, collections, policies, shipping and returns, and keeps them in sync as your catalog changes.
How is this different from a robots.txt or sitemap?
They do different jobs. robots.txt tells crawlers what they may access. A sitemap lists your URLs for search engines. llms.txt is written for AI: a clean, human-readable summary of your most important pages so an assistant can understand your store quickly. A complete setup uses all three.
