AI Training Crawler
GPTBot is a web crawler operated by OpenAI to collect publicly available data from the internet. This data is used to train and improve AI models like ChatGPT, GPT-4, and other OpenAI products.
Launched in August 2023, GPTBot quickly became one of the most talked-about crawlers in the webmaster community. OpenAI introduced it with a clear opt-out mechanism via robots.txt, giving website owners control over whether their content is used for AI training.
GPTBot filters out paywalled content, content that violates OpenAI's policies, and personally identifiable information (PII). It aims to collect high-quality, publicly accessible text data.
To prevent GPTBot from crawling your website and using your content for AI training, add the following to your robots.txt file:
robots.txt
User-agent: GPTBot Disallow: /
Blocking GPTBot will prevent your content from being used to train future OpenAI models. However, content already collected before you added the block may have been used in previous training runs. Blocking GPTBot does not affect how ChatGPT references your site in conversations.
User-Agent string: Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; GPTBot/1.0; +https://openai.com/gptbot)

Filters out paywalled content and PII by design
Supports partial blocking — you can allow access to some paths and block others
Separate from ChatGPT-User (the bot that fetches pages when ChatGPT browses the web in real-time)
Allowing GPTBot to crawl your content means it may be used to train future OpenAI models. This could result in ChatGPT and other tools having better knowledge about your brand, products, or industry — potentially leading to more accurate AI-generated recommendations.
Many publishers and content creators have chosen to block GPTBot as a matter of principle, arguing that AI training on their content without compensation is unfair. Others see it as an opportunity for increased AI visibility. The choice depends on your content strategy.
