An llms.txt file is a plain-text document placed at the root of your store that tells AI language models — like ChatGPT or Perplexity — what your store sells, who you are, and which pages are most important. It is to AI what robots.txt is to search engine crawlers.
Yes. Major AI platforms actively look for llms.txt files when researching products and brands. Having a well-structured file increases the likelihood that AI assistants recommend your store when users ask relevant questions.
The generated llms.txt is compatible with all major AI platforms including ChatGPT, Perplexity AI, Claude (Anthropic), Google Gemini, Grok (xAI), and Microsoft Copilot — essentially any AI that follows the llms.txt standard.
Absolutely. We only read the product and content data necessary to build your file. We never sell your data. Everything is encrypted in transit and at rest. See our Privacy Policy for full details.
The app listens to Shopify webhooks. When you add, update, or delete a product, the file is automatically regenerated in the background. You can also trigger a manual sync at any time from the dashboard. You control when the updated file is published and made publicly visible.
Yes. From the Customize page in the app you can write a custom store description for AI platforms, choose which product sections and page types to include, and control the overall structure of the generated file.
Syncing generates a new draft of your llms.txt file based on your current store data. Publishing makes that draft publicly accessible to AI platforms via your store URL. This two-step process lets you review content before it goes live.
The core features are completely free. Install the app from the Shopify App Store and start making your store AI-visible in minutes — no credit card required.
Once published, your file is accessible at https://your-store.myshopify.com/llms.txt. It is served via the Shopify App Proxy and is readable by any AI platform or browser.
Uninstalling removes all your store data from our servers within 30 days. Your llms.txt will no longer be served through the app proxy. Your Shopify store itself is not affected in any way.
