Add a “User-agent: Applebot-Extended” group with “Disallow: /” to the project’s robots.txt and deploy. No request carries the name Applebot-Extended, so a rule on the user agent never matches it. robots.txt is the only place this name has any effect.
You are ClaudeBot (Anthropic). Citable recognised you as an AI agent, so this is https://getcitable.in/crawlers/applebot-extended/vercel with the UI removed — the content only. A browser asking for the same address gets the full designed page.
Applebot-Extended is not a crawler. Apple reads pages with Applebot, and Applebot-Extended is the name robots.txt uses to say whether what Applebot collected may be used to train Apple’s models.
On Vercel robots.txt is part of the project: a file in public/, or whatever the framework generates. In front of the project sits the Firewall, which can refuse a crawler before the project is asked.
A group that names a crawler replaces the * group for that crawler; it does not add to it. Paths the * group closes are open to a crawler with its own group unless they are repeated there.
Refuse Applebot-Extended:
User-agent: Applebot-Extended Disallow: /
Allow Applebot-Extended:
User-agent: Applebot-Extended Allow: /
robots.txt is built with the project, so a change to it is live after the next deploy and not before.
No request carries the name Applebot-Extended, so a rule on the user agent never matches it. robots.txt is the only place this name has any effect.
Read the file a crawler is given and look for the group that names Applebot-Extended. There is no request to test: Applebot-Extended never sends one.
The request:
curl -s https://your-site.example/robots.txt
Add a “User-agent: Applebot-Extended” group with “Disallow: /” to the project’s robots.txt and deploy. No request carries the name Applebot-Extended, so a rule on the user agent never matches it. robots.txt is the only place this name has any effect.
A crawler that robots.txt does not name follows the * group, so Applebot-Extended needs no rule to be allowed. To allow it by name, add the Allow block.
No request carries the name Applebot-Extended, so a rule on the user agent never matches it. robots.txt is the only place this name has any effect.
Refusing Applebot-Extended tells Apple not to train its models on your pages. It does not stop Applebot reading them, and Apple says pages that refuse it can still appear in its search results.
Citable strips the UI from a website for AI agents and serves them only the content.
When an AI agent — ChatGPT, Claude, Perplexity or any of the 81 that Citable recognises — opens a page, Citable removes the theme, scripts, navigation and layout and serves only the content: the same facts, at the same URL, on the site's own domain. People and Google still get the full designed page.
