- OpenAI is piloting a 'Writing Style' feature for ChatGPT that learns users' voice by referencing examples from connected apps rather than requiring pasted samples
- Writing Style pulls from three categories: Messaging (Slack), Documents (Google Drive, Notion), and Email (Gmail), as shown in the onboarding screen
- OpenAI confirmed the test is live for a small group of users but has not announced a wider rollout timeline
- OpenAI's approach differs from Anthropic's Claude Styles, which relied on users uploading or pasting writing samples to generate a custom style
- ChatGPT gains a larger and more varied sample set by reading existing messages, documents, and emails, allowing it to mimic tone across different writing contexts without re-prompting
Why it matters: By drawing directly from Slack, Gmail, Google Drive, and Notion, ChatGPT can study a user's voice across three distinct writing contexts (messages, long-form documents, email) without manual uploads, removing the per-prompt friction of re-explaining tone. That gives OpenAI a personalization edge over Anthropic's upload-based Styles, at the cost of granting the model deeper read access to personal communication streams.
