OpenAI has made the decision to prohibit indexing of public ChatGPT dialogues by search engines following criticism over the exposure of confidential information online. This was reported by OpenAI's security specialist, Dane Staky, on social media.

The previous feature that allowed the indexing of user conversations raised concerns as instances emerged where individuals shared illegal information or business secrets. Such data could appear in search engine results if published through the chat sharing feature.

Starting August 2, 2025, OpenAI plans to block the indexing of such materials. The company is also considering additional measures to limit access to accidentally published user data.

The chat sharing function was introduced in 2023 as a tool for sharing interesting examples of interaction with ChatGPT; however, the company did not anticipate the extent to which these public links could spread.

Furthermore, it’s worth noting that OpenAI recently added a new feature to ChatGPT — Study Mode, which allows users to solve tasks step by step.
