Understanding the AI Store File (llms.txt)

The AI Store File, also known as llms.txt, is a small public file that helps AI systems understand your store. Think of it as your store’s “AI business card” — a simple summary that tells AI assistants what you sell, what makes your brand unique, and where to find key pages on your website.

What it does

When AI crawlers (like those from ChatGPT, Gemini, or Perplexity) visit your site, they look for structured data they can easily read.

The llms.txt file gives them a clean, readable summary of your store, including:

• Store name and domain
• What you sell and your key collections
• Links to your main pages, products, and policies
• Notes about your brand values or specialties

This means your store is more likely to appear correctly when shoppers ask AI assistants questions like “Where can I buy vintage Polaroid cameras?” or “Best handmade soap stores online.”

How the app creates it

You don’t have to write or upload anything yourself. Synctrack LLMs Index automatically generates and updates your llms.txt file from your public Shopify data — products, collections, and store details already visible online.

It refreshes regularly (about once a week) so the information stays accurate as your store changes. You can also click Refresh now anytime after major product or collection updates.

Where to find it

Once enabled, your llms.txt file is publicly accessible at your store’s root domain.

Example: https://yourstore.myshopify.com/llms.txt

You can open this link in your browser to preview what AI assistants will read.

Privacy note

The llms.txt file only includes public data that’s already visible on your store — such as product titles, collection names, and descriptions. It never includes customer, order, or payment information.
