Most users of South Korean AI character chat service Zeta are teenagers or younger, while Crack also has nearly half of its users in that age group, MobileIndex data showed. Operators say they separate adult content and apply identity checks, but questions remain about keeping conversations safe in general content.

OpenAI has added voice work features to the ChatGPT desktop app, enabling users to hold conversations while carrying out tasks through GPT Voice. The update is based on the upgraded voice mode GPT-Live that was first applied on mobile this month. GPT Voice is available on macOS and Windows 11, while Mac users can use Appshots so ChatGPT can reference the active window for better context. The feature also links to computer-use functions, local files, plugins and iOS remote capability.
