OpenAI adds ‘Reference my writing style’ feature to ChatGPT, lets AI mimic your voice
OpenAI has quietly rolled out a new personalization option inside ChatGPT called “Reference my writing style.” The tool, accessed through the Personalization settings, can scan a user’s past writings stored in services such as Google Drive, Gmail, Outlook, Slack, Microsoft Teams, SharePoint and Notion. Once granted permission, users can ask ChatGPT to draft new content “using my writing style,”…
Key points
- OpenAI’s hidden “Reference my writing style” option lets ChatGPT learn a user’s tone from Google Drive, Gmail, Slack, and other platforms
- The tool, confirmed by product chief Thibault Sottiaux, generated a 1,000‑word document in the author’s voice using GPT‑5.6
- AI‑detector GPTZero flagged the output as AI‑generated, highlighting concerns over authenticity and watermarking
The feature was confirmed by OpenAI product chief Thibault Sottiaux and was demonstrated by a writer who let the system analyze a recent story about OpenAI’s Astra model. Using GPT‑5.6, ChatGPT produced a roughly 1,000‑word proposal that mimicked the author’s quirks, phrases and punctuation. However, the AI‑detection service GPTZero immediately flagged the text as highly likely to be AI‑generated, underscoring the difficulty of distinguishing personalized AI output from genuine human writing.
The rollout raises questions about authenticity, plagiarism and the need for watermarking or other safeguards as AI tools become capable of impersonating individual writing styles.
