"ChatGPT" Learns Your Style to Write on Your Behalf

Your emails, documents, and conversations could become the means by which the chatbot ChatGPT learns to communicate in your unique style, enabling it to draft texts in a manner closer to your usual writing habits. OpenAI is currently testing a new feature in ChatGPT called Writing Style, offering a clever approach to customizing writing style. Instead of requiring users to explain their writing tone each time, the feature analyzes how they actually write across apps linked to their account, then attempts to mimic their style, according to a report published by Digital Trends.

According to the feature’s initial setup screen, ChatGPT relies on examples from three primary sources: conversations, documents, and emails. For instance, users can connect Slack to draw examples from their messages, Google Drive or Notion to analyze their documents, and Gmail to examine their email writing style. After linking these apps and selecting the “Use writing style” option, ChatGPT is expected to begin relying on users’ actual writing patterns rather than relying solely on general instructions. This means users won’t need to write prompts such as “Write this message in an informal tone”; instead, they can simply leave their previous Slack messages and other content for the model to infer their writing style.

The concept may seem familiar, as Anthropic previously experimented with a similar idea through the Styles feature in Claude. This feature allowed users to upload or paste samples of their writing, enabling Claude to analyze them and generate a customized style based on those examples. However, Anthropic later discontinued the Styles feature and integrated its functionality into Claude Skills, which does not offer the same ease of setup.
