Visibility Mesh and Arc: llms.txt, what each one is built for

We read the Arc: llms.txt listing on the Shopify App Store, apps.shopify.com/llms-txt-generator-ai-search, on November 9, 2026. Visibility Mesh prices come from our own product pages on the same day.

Arc: llms.txt is a Shopify app from ArcSpeed that creates, hosts and refreshes an llms.txt file, as its listing described it on November 9, 2026. Visibility Mesh checks whether AI assistants can read the store that file points to, including its crawler access, product pages and schema.

What does Arc: llms.txt do?

The Arc listing describes llms.txt as a file for AI that works like robots.txt and sitemap.xml together. It says the app creates one in one click. The file covers products, collections, blog posts and pages, and the app refreshes it as the store changes.

The listing shows a free plan with a weekly sync. A Pro plan adds a daily sync, FAQ customization and multilingual support. Arc fits a merchant who wants the file in place and current without editing it by hand.

What does Visibility Mesh check beyond the file?

Say a ceramics shop has 80 products and a fresh llms.txt file. Each mug page states its capacity, material and dishwasher safety only in a photo. The file sends an assistant to pages whose text cannot answer a buyer who asks whether the mug can go in the dishwasher. Our scan names those pages and the field to fill in, under Products, then the product, then Description. Our guide to fixing a thin product page shows the test we use.

An llms.txt file tells an assistant where the pages are. Visibility Mesh checks what the assistant finds once it gets there. Our scan checks whether each major AI crawler may fetch the pages under robots.txt. It reads the Product structured data and visible text on each one, and it checks the links between collections, products and posts.

Our Shopify app starts at $29 a month. Starter includes 12 rescans a month, and every plan begins with a 7 day free trial.

When is Arc: llms.txt the better choice?

Arc: llms.txt is the better choice when the merchant mainly wants an llms.txt file. In that case the merchant wants an llms.txt file created, hosted and kept in sync, and the rest of the store is in good shape. Its free plan covers up to 200 products, which fits a small catalog. We handle llms.txt as one item among many, so a merchant who wants only the file may not need the rest.

Our Academy also explains the difference Product schema makes. If you want to see your own store the way an assistant does, you can run the free Visibility Mesh scan of 5 key pages.

You can keep it. Our scan reads the llms.txt file a store already has and reports on it with everything else.

What does the Visibility Mesh scan read on each page?
