What an AI assistant fetcher does

An assistant fetcher visits only when someone asks an AI assistant a question that needs your page. Each visit stands for a real person, often one who is about to click through, so blocking it usually costs you readers.

OpenAI says robots.txt rules may not apply, because a person started the request.

Block or allow ChatGPT-User in robots.txt

Add one of these to the robots.txt file at the root of your domain. Crawlers read it before they fetch anything else.

Block ChatGPT-User

User-agent: ChatGPT-User
Disallow: /

Allow ChatGPT-User

User-agent: ChatGPT-User
Allow: /

ChatGPT-User is an AI assistant fetcher run by OpenAI. Opens a page when someone using ChatGPT or a custom GPT asks about it.

Not always. ChatGPT-User fetches pages for a person, and OpenAI says robots.txt may not apply. OpenAI says robots.txt rules may not apply, because a person started the request.

Add "User-agent: ChatGPT-User" and "Disallow: /" to your robots.txt. Since robots.txt may not stop it, block it at your firewall or server too.

Check the request's IP address against the list OpenAI publishes. A user agent alone proves nothing, since any script can copy it.

Indirectly. ChatGPT-User opens your page because a person asked about it, and the answer can link back to you.

Usually not. Each visit stands for a person asking about your page, so blocking ChatGPT-User turns readers away.
