ChatGPT-User
ChatGPT-User doesn't crawl the web on its own: it only visits your page when a real ChatGPT user asks a question that needs current data from your site, or uses a custom GPT. It's the equivalent of a potential customer opening your website, but through AI. Each visit usually means your content is about to be cited in an answer.

Should I block ChatGPT-User?
It's not advisable. If you block it, ChatGPT won't be able to read your site when a user asks about you or your industry in real time, and the answer will be built with information from your competitors.
Does ChatGPT-User respect robots.txt?
No. Since December 2025, OpenAI documents that only GPTBot and OAI-SearchBot follow robots.txt rules. Since ChatGPT-User visits are triggered by a person, they aren't governed by robots.txt, so blocking it there won't stop it — you'd need to do that at the server level.
How do I know if ChatGPT-User visits my site?
Search for "ChatGPT-User" in your server logs. If it shows up, it means real ChatGPT users are asking questions that lead the AI to your site — a very good sign for your business.
