OpenAI's ChatGPT Work for enterprise users has recently added a feature that learns and mimics users' personal writing styles by analyzing historical writing content from connected third-party applications. This feature is currently in a limited testing phase.

The feature captures commonly used phrases, signature habits, and writing quirks by analyzing historical writing samples from connected accounts such as Gmail, Google Drive, Slack, and SharePoint. Users can configure this in the "Writing style" option under the "Personalization" settings on the web interface, allowing AI-generated emails, documents, and message drafts to better reflect the user's authentic tone.

Reports indicate that early testing users have positively evaluated the feature for maintaining consistent content style in professional contexts and aligning with personal expression habits. However, some users have expressed concerns regarding privacy issues and whether this feature will expand to other usage modes of ChatGPT in the future.

According to another English report, this feature is currently being tested with a limited number of users, and the system prompts that "ChatGPT will refer to examples in your connected applications to mimic your writing style." Users can provide writing samples for different categories such as messages, documents, and emails. OpenAI has confirmed that it is testing the "Writing Style" feature but has not disclosed a specific timeline for a broader rollout.

The report notes that OpenAI has not disclosed specific data processing details for this feature, including the storage duration of reference writing samples and whether these samples will be used for model training. The company currently has privacy protection options like "Lockdown Mode," but it has not clarified whether similar protective mechanisms will apply to this new feature.

The report compares this feature with Anthropic's "Styles" feature for Claude, pointing out that both approaches are similar, but ChatGPT's method involves directly connecting to third-party applications used by the user to extract writing samples, rather than requiring users to manually upload example texts.
