# ChatGPT-User

OpenAI's crawler: what it does, robots.txt handling per the operator, and observed behaviour on this property.

- Operator: OpenAI
- Purpose: User-requested fetches | operator's words: "certain user actions in ChatGPT and Custom GPTs"
- robots.txt token: `ChatGPT-User`
- Appears in access logs: yes
- User-agent: `Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko); compatible; ChatGPT-User/1.0; +https://openai.com/bot`
- robots.txt: May not honor robots.txt. OpenAI states robots.txt rules may not apply to it because the fetches are initiated by a user, not a crawl schedule.
- IP list: https://openai.com/chatgpt-user.json
- Verification: Match the requesting IP against the published list.
- Documentation: https://developers.openai.com/api/docs/bots (read 2026-08-04)
- Note: A hit from ChatGPT-User means a person asked ChatGPT something and it opened this page to answer. That is exactly the event AI visibility tools try to measure.
