Kai is an iPhone system keyboard app whose core idea is to embed ChatGPT's capabilities directly into the iPhone keyboard, so that AI assistance can appear in any app that can invoke the keyboard.
Main capabilities: According to the official introduction, Kai lets users "use ChatGPT anywhere on iPhone" to "improve writing, spark creativity, and save time." In other words, it is positioned as a general-purpose AI input assistance tool, rather than being limited to one specific app.
How to use it: As a keyboard-type tool, it needs to be used through the iPhone's system keyboard mechanism, that is, by bringing up the Kai keyboard in an app where text input is needed, thereby obtaining AI assistance within that app. Apart from the above description, the official materials do not provide specific installation steps, supported app scope, supported languages, the model version invoked, or other technical details; this content is not currently available.
Use cases: From the official positioning, it is suitable for iPhone users who need to obtain AI writing and creative assistance at any time during everyday phone input, for example in chatting, email, notes, or other text input scenarios.
Limitations and supplements: The information currently confirmable is limited to the fact that it is aimed at iPhone, integrates ChatGPT in the form of a keyboard, and provides writing and creative assistance. Regarding the charging model, price, whether an account login is required, whether non-English languages are supported, and whether other devices such as iPad are supported, the materials do not explain any of these, and they are not currently available.
