Are you ChatGPT visible? 

The way AI platforms discover your store is changing. Just as search engines once needed robots.txt to understand what to crawl, AI systems now need a clear signal too, and that’s where llms.txt comes in.

It’s a short file that tells tools like ChatGPT, Perplexity, and Claude what your brand sells, who it’s for, and which pages matter most. Think of it as a cheat sheet for AI, helping large language models interpret your store the way you want.

What to Include in an llms.txt File

Keep it simple and structured. Your goal isn’t to sell, it’s to clarify.

Include:

• Who you are (one short paragraph)
• What you sell (broad categories, not every product)
• Who your customer is
• Your key differentiators
• Links to important pages

That’s it. It’s a summary that helps AI understand context, not a human sales pitch.

How to Add llms.txt to Your Shopify Store

There are two easy methods.

1. Use the Generator

The simplest path: use our llms.txt Generator.
Enter your store URL, it creates the file for you, which you can download and upload automatically.

2. Manual Method

If you prefer to do it yourself:

1. Create a text file named llms.txt.
2. Add your brand summary and key links (as shown above).
3. Upload it to Shopify → Settings → Files.
4. Create a redirect from /llms.txt to the uploaded file URL.

The generator handles all this automatically.

Does llms.txt Improve AI Visibility?

It’s not magic, but it helps more than doing nothing.

AI systems like ChatGPT and Perplexity crawl your content differently than Google. They rely on structured hints and summaries to understand your brand context and product intent.

The llms.txt file gives them that structure. It’s a 10-minute setup that improves how AI models interpret your store.

Combined with proper product schema (see Product Pages & Structured Data) and ACP compliance, it becomes part of a complete AI Optimization (AIO) foundation.

If you haven’t yet optimized your store for AI, start with the AI Visibility Audit to see what ChatGPT actually reads from your Shopify feed.

Bottom Line

llms.txt is your store’s introduction to AI systems, a simple file that helps them understand your brand the way you intend. It’s about giving AI context. And in the era of AI commerce, the brands that communicate clearly are the ones that get discovered.
