ChatGPT-User— search-time from OpenAI
Fetches pages when a ChatGPT user follows a link or asks for a browse.
ChatGPT-User is the on-demand fetcher used when a ChatGPT user clicks a citation or explicitly asks Claude to read a URL. Unlike GPTBot (training) it acts only when a user requests it. Allow it so that ChatGPT can actually quote your content when a user asks about your domain.

What is ChatGPT-User?

How can I check whether my site is ready for ChatGPT-User?
Run a free check at https://agentics.page — it audits whether your robots.txt allows the right bots, whether you publish llms.txt and JSON-LD structured data, whether your content is server-rendered, and whether ChatGPT-User can actually consume your site.
Is your domain ready for ChatGPT-User?
agentics checks whether your robots.txt allows the right bots, your llms.txt is in shape, your JSON-LD and SSR content are visible, and whether ChatGPT-User can actually use your domain.
