Chai UI is an open-source component project for building interfaces to AI applications. Its homepage presents React and Vue packages, shared design tokens and a working prompt-composer example. The stated interface use cases include choosing models, refining prompts, analyzing media and editing images, with source code and component documentation linked from the landing page.
The project is a UI layer rather than a hosted model provider. In the examples, the application receives the composer's submitted value through its own handler, leaving the developer to connect model calls and other backend behavior. Teams evaluating Chai UI should inspect the current component API, styling packages and framework support rather than assume that a visual control includes the underlying generation service. It is aimed at developers who want reusable interface pieces for their own AI product, not users looking for a finished all-in-one chat application.
