GPTBot, OAI-SearchBot, ChatGPT-User
The company behind ChatGPT has three visitors. GPTBot collects pages that may be used to train its AI models. OAI-SearchBot indexes pages for ChatGPT's search. ChatGPT-User fetches a page when someone asks ChatGPT about it, so that visit is prompted by a person in a chat.
Worth knowing: OpenAI announced GPTBot in August 2023 along with a way to block it in robots.txt, and within weeks many large news sites had done so.
