The GPT Bot from the American company OpenAI is a web crawler designed to exhaustively explore and index all data, resources, and information available on the internet. Its primary mission is to gather data to improve the future GPT-5 artificial intelligence. When the bot visits a website, its visit can be identified in the server’s connection logs by the identifier “Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; GPTBot/1.0; +https://openai.com/gptbot)”.

If you wish to prevent the GPT Bot from accessing your site, you can do so by modifying your robots.txt file. Simply add the following lines:

# Disallow GPT Bot
# https://definitions-digital.com/seo/gpt-bot

User-agent: GPTBot
Disallow: /
