OpenAI bots

4 bots in the directory · Reviewed July 2026

OpenAI operates ChatGPT and runs three bots with strictly separated jobs: GPTBot collects training data, OAI-SearchBot builds the ChatGPT search index, and ChatGPT-User fetches pages live on user request. Each honors its own robots.txt token, so training and search visibility are independent decisions.

Fetches pages in real time when a ChatGPT user asks about them or clicks a link in a conversation.
