In plain text
llms.txt and one Markdown document per entity, for the agents that read text first.
Features · Publish
llms.txt, and a document for every product.
Clione generates an llms.txt for your store and a Markdown document for every product, category, collection and content page. AI agents read the whole catalog as plain text, on your store's own domain.
A product, as an AI agent reads it
This is the shape of one product's document: what the product is, who it suits, the words shoppers search with and the questions it answers, in plain Markdown with nothing around it. Every product, category, collection and content page gets one, served from your store's own domain.
Markdownone product's document

Yes. The medium feel lets the shoulder sink in.
Shortened for the page, and filled from an invented store: yours is written from your own catalog. The llms.txt file sits above all of these documents and tells a model what the store is.
The file
An llms.txt for the whole store.
llms.txt is a proposed convention: one Markdown file that tells a language model what a site is about. Clione generates your store's from its catalog and serves it on your own domain: on Shopify under /apps/clione/, on BigCommerce from a subdomain you point at Clione.
- How assistants read a catalog: ChatGPT shopping and agentic commerce
- Separate from Shopify's own llms.txt, which stays as Shopify serves it
The documents
One Markdown document per entity.
Each product, category, collection and content page gets a document of its own. An agent that wants one product reads that product, without the theme, the scripts and the menus around it.
- Products, categories, collections and content pages
- Carrying the per-product enrichment: what it is, who it suits, the words people search with
- The product's questions and answers, which a public FAQ API serves as well
Kept current
Gone from the store, gone from the agents.
A product deleted in the store disappears at once from what Clione serves to AI agents. No agent reading from Clione is told about something you no longer sell.
Three ways in
The same catalog, wherever an agent reads.
Before you switch it on
What people ask about llms.txt.
What is llms.txt?
A proposed convention: a Markdown file at a known address that tells a language model what a site is and where its most useful content lives. More on llms.txt, in the glossary.
Where are the files served from?
From your store's own domain. On Shopify, through Shopify's app proxy, under /apps/clione/ on your store's address. On BigCommerce, from a subdomain of your domain that you point at Clione with one DNS record, set up once with you. Nothing on your theme has to change.
Which pages get a document?
Every product, category, collection and content page Clione syncs from a Shopify or BigCommerce store. One entity, one document.
What happens when I delete a product?
It disappears at once from what Clione serves to AI agents, and from Clione itself after a short grace period.
Can agents read the FAQs as well?
Yes. The questions Clione manages reach the product page as FAQPage markup, and a public FAQ API serves them too. How the questions are written.
What does it cost?
Nothing, during the beta. Clione is taking selected clients into this stage, in limited places, free of charge, and prices are published when the beta ends in Q1 2027.
