Google Chrome is developing new generative AI features, including customizable themes and writing assistance. This feature allows users to select theme categories, adjust mood and tone, and generate personalized Chrome browser themes. Currently, this feature is limited to the experimental browser version Chrome Canary and is not guaranteed to work as expected. Additionally, Chrome is also developing a generative AI writing tool that can provide contextual writing suggestions for posts or online comments. These features may be released in the future, but the exact release time is yet to be determined.
