# AI SDK UI

[AI SDK UI](/docs/ai-sdk-ui) is designed to help you build interactive chat, completion, and assistant applications with ease.
It is framework-agnostic toolkit, streamlining the integration of advanced AI functionalities into your applications.

AI SDK UI contains the following hooks:

## UI Framework Support

AI SDK UI supports the following frameworks: [React](https://react.dev/), [Svelte](https://svelte.dev/), and [Vue.js](https://vuejs.org/).
Here is a comparison of the supported functions across these frameworks:

| Function                                                  | React               | Svelte                               | Vue.js              |
| --------------------------------------------------------- | ------------------- | ------------------------------------ | ------------------- |
| [useChat](/docs/reference/ai-sdk-ui/use-chat)             | <Check size={18} /> | <Check size={18} /> Chat             | <Check size={18} /> |
| [useCompletion](/docs/reference/ai-sdk-ui/use-completion) | <Check size={18} /> | <Check size={18} /> Completion       | <Check size={18} /> |
| [useObject](/docs/reference/ai-sdk-ui/use-object)         | <Check size={18} /> | <Check size={18} /> StructuredObject | <Cross size={18} /> |
