# 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 a 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/), [Vue.js](https://vuejs.org/),
[Angular](https://angular.dev/), and [SolidJS](https://www.solidjs.com/).

Here is a comparison of the supported functions across these frameworks:
