Visits a page when a ChatGPT or custom GPT user asks something that needs it, or through GPT Actions. OpenAI says it does not crawl automatically and does not decide whether content appears in ChatGPT search.

Follows robots.txt

Partly. The company says that because these fetches are started by a user, robots.txt rules may not apply to them.

Block or allow it in robots.txt

Add these lines to the robots.txt file at the root of your domain. To block it everywhere:

User-agent: ChatGPT-User
Disallow: /

To allow it everywhere except one folder:

User-agent: ChatGPT-User
Disallow: /private/

This bot does not always follow robots.txt. To keep it out for sure, block it on your server or firewall by user agent and, where published, by IP range.

Is it really this bot?

Anyone can copy a user agent. To be sure a request comes from OpenAI, compare its IP address with the ranges the company publishes.
