Can AI assistants read at5.nl?

Measured on 2026-09-19 by asking the site 7 times — once as a browser, once as each of the 6 crawlers that feed ChatGPT, Claude, Perplexity, Gemini, Meta AI, Apple Intelligence and Doubao — and comparing what came back. The AI-training opt-out tokens that never crawl are read from robots.txt instead.

C63 / 100

Method. Six live HTTP requests plus robots.txt, llms.txt, sitemap.xml and security.txt, 12-second timeout each, from a single vantage point. Blocking AI crawlers is a legitimate choice, not a failure: this page records what is true, not what should be. Domain comes from a shop-platform seed (Shopify/WooCommerce/Magento/BigCommerce/Shopline fingerprint or JSON-LD price), not the Tranco traffic ranking. One page per domain — the homepage — is audited.
