Frequently Asked Questions

What is an llms.txt file?

An llms.txt file is a standardized plain text file that helps AI language models understand what a website is about. It works like robots.txt does for search engine crawlers, but for AI: it tells ChatGPT, Perplexity, Claude, and other AI systems what your business sells, how to describe you accurately, and where to find your key pages. Without it, AI engines have to guess what your store is about from your HTML alone.

Do I need llms.txt if I already have a sitemap?

Yes. A sitemap tells search crawlers which pages to index. llms.txt tells AI models what your business actually does, what you sell, and how you want to be described. They serve completely different purposes. Your sitemap helps Google find your pages. Your llms.txt helps ChatGPT explain your business accurately to shoppers who ask about it.

Which AI engines use llms.txt?

ChatGPT (via its browsing feature), Perplexity, Claude, and other AI systems that crawl websites can read your llms.txt file to get structured context about your business. The format is an open standard proposed by answer.ai, with growing adoption across major AI platforms.

Where do I put my llms.txt file?

It goes in your website root directory at yourdomain.com/llms.txt. For Shopify stores, upload it as an asset file via Online Store → Themes → Edit code → Assets and it will be accessible at your root domain. No app or plugin required.
