OpenAI, the company behind the popular AI chatbot ChatGPT, is developing a new feature that allows the AI to replicate a user's writing style by analyzing their work tools. This feature, currently in testing, enables ChatGPT to refer to examples from a user's connected applications to mimic their preferred writing style. This means the AI can learn from texts written in instant messaging apps, emails, and other documents stored in the cloud, including platforms like Slack, Google Drive, Notion, and Gmail. The function helps ChatGPT understand the difference between a formal email and a casual message sent in a team chat. This new feature has raised privacy concerns, as it involves collecting data from connected applications. Unlike the "Styles" feature in another AI model called Claude, which requires users to provide text samples to refine responses, OpenAI's approach automates the data collection process. This means users do not need to manually input text samples for the AI to learn from. However, there is currently no public information about how the collected data will be processed, stored, or used by the AI model. The feature seems to be in a testing phase, with only a small group of users having encountered a new home screen that describes the functionality. OpenAI has confirmed that it is working on this feature but has not provided a specific release date. Experts and users are hoping that OpenAI will offer more transparency about how this feature works and what it means for user privacy and data protection. As AI tools become more integrated into daily work and communication, features like this highlight the growing importance of balancing innovation with user privacy. While the ability to replicate a user's writing style can enhance the AI's usefulness, it also raises important questions about data security and user consent. OpenAI will likely face pressure to clarify its practices and ensure that users feel confident about how their data is being used.
