Questions

What is ChatGPT-User?

Fetches a page when ChatGPT or a custom GPT opens it to answer a person's question. MetricRaven groups it under AI answers: assistants opening a page because a person asked about it.

How do I verify that a request really comes from ChatGPT-User?

Check both the user agent and the IP. Requests from ChatGPT-User contain "ChatGPT-User" in the user agent and come from the IP ranges OpenAI publishes (https://openai.com/chatgpt-user.json). A request with the name but another IP is likely spoofed.

How do I block or allow ChatGPT-User?

Add a robots.txt group for "ChatGPT-User" with the paths to allow or disallow. Fetchers that act for a user may ignore robots.txt; block those at your server or firewall instead.

How can I see when ChatGPT-User visits my website?

Most crawlers never run JavaScript, so browser analytics miss them. MetricRaven's @metricraven/ai-crawl package reports crawler requests from your server, verifies their IPs against published ranges, and shows which pages each crawler reads.
