OpenAI Introduces Feature Letting ChatGPT Mimic Users' Writing Style by Scanning Emails and Messages
OpenAI has launched a new feature that allows ChatGPT to replicate a user's personal writing style by analyzing their emails and messages. The update, called Writing Styles, has been rolled out for ChatGPT Work, the company's agentic AI tool.
According to OpenAI, the feature enables ChatGPT to study a user's writing patterns and replicate them in future drafts. This includes distinctive traits such as favorite phrases, specific sign-offs, and capitalization habits. The announcement was made via the official ChatGPT account on X, which stated that ChatGPT Work can now identify what makes a person's writing unique and reflect that in its output.
The development comes amid growing conversation around "AI slop," a term used to describe content that appears obviously generated by artificial intelligence. OpenAI's new feature aims to make AI-assisted writing feel more natural and personalized.
To use Writing Styles, users must connect ChatGPT Work to apps they use regularly, including Gmail, Google Drive, Slack, and SharePoint. Once granted access, the AI reviews emails and messages to identify patterns in vocabulary, tone, sentence structure, and punctuation. It then applies these patterns to new content it generates. While OpenAI has not detailed the exact mechanism behind the feature, it likely relies on natural language processing techniques that break down text to detect stylistic and emotional patterns unique to each user.
Currently, Writing Styles is exclusive to ChatGPT Work and is available on the web for all paid plans with access to that tool. Users can enable it through the Settings menu under Personalisation options. OpenAI has not indicated whether the feature will be extended to the standard ChatGPT chatbot.
OpenAI is not the first company to introduce such a feature. Anthropic previously released a similar Styles function for its Claude AI, which lets users upload or paste writing samples to create a customized style based on their communication habits.
The rollout of Writing Styles comes shortly after OpenAI unveiled GPT-6 Astra, which the company describes as its most advanced AI model to date. Nvidia CEO Jensen Huang has referred to Astra as representing "AGI," or artificial general intelligence.
