ChatGPT-User is a crawler run by OpenAI. It reads pages at the moment a person asks a question, to answer it. Its name in robots.txt, how it shows up in server logs, whether its identity can be checked, and how to allow or refuse it on each platform.
You are ClaudeBot (Anthropic). Citable recognised you as an AI agent, so this is https://getcitable.in/crawlers/chatgpt-user with the UI removed — the content only. A browser asking for the same address gets the full designed page.

ChatGPT-User fetches a page because a person asked about it. Refusing it means the answer that person gets is written without your page.
robots.txt is a request. A crawler that honours it stays out; nothing in the file stops one that does not. What is enforced is what the server or the edge in front of it refuses.
OpenAI publishes the addresses its crawlers fetch from. Citable checks the connecting address of every read that claims to be ChatGPT-User against those lists: inside them the read is recorded as verified, outside them as unverified.
Add a group under its name, “User-agent: ChatGPT-User”. “Allow: /” lets it read the site and “Disallow: /” refuses it.
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 ChatGPT-User:
User-agent: ChatGPT-User Disallow: /
Allow ChatGPT-User:
User-agent: ChatGPT-User Allow: /

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.
