OpenAI has officially announced a new feature for ChatGPT called "Writing tones". According to a brief update from the official ChatGPT account on July 23, 2026, this update allows users to easily adjust the style and nuance of their text directly within the composing interface. This is seen as an important step toward optimizing the writing experience and personalizing the chatbot's output, saving users from having to type lengthy prompts to shape their text.
Background & Causes
Prior to this feature, ChatGPT users had to manually write prompts like "write in a formal tone" or "make this article more friendly" to change the writing style. This manual configuration sometimes produced inconsistent results and was time-consuming for casual users without technical prompt-engineering experience.
The release of "Writing tones" aims to simplify this process with intuitive, pre-built options in the user interface. This reflects a broader trend of integrating deep writing assistance tools as competitors like Anthropic's Claude and specialized writing software continuously upgrade their user experiences.
Technical & Technological Analysis
Technically, this feature operates by directly integrating system instructions regarding tone into the underlying Large Language Model (LLM). When a user selects a specific tone—such as professional, casual, persuasive, or analytical—the system automatically adjusts parameters or applies an underlying prompt to shape the output text.
This provides better control over vocabulary consistency, sentence structure, and style without requiring users to have expert prompt engineering skills. The ability to handle diverse context settings shows that OpenAI has optimized its latest GPT models to respond more precisely to stylistic demands.
Expert Opinions & Insights
According to tech analysts, adding visual writing tone options is a necessary but not surprising improvement in the current landscape. Many other AI writing tools, such as Grammarly, Jasper, or even Notion AI, have offered similar capabilities for a long time and achieved great success. OpenAI directly integrating "Writing tones" into ChatGPT indicates that the company is striving to transform ChatGPT from a pure Q&A chatbot into a comprehensive writing and creation platform, directly challenging the market share of specialized writing tech companies.
Impact & Future
This update promises to save significant time for office workers, content creators, and students when refining emails, articles, or business reports. In Vietnam, where the demand for using ChatGPT in both English and Vietnamese writing tasks is continuously growing, the "Writing tones" feature will actively support generating texts suitable for specific local business communication contexts. In the near future, allowing users to train their own custom personal tones could be OpenAI's next step to maintain its leadership in the generative AI era.
