# AI Elements

[AI Elements](https://www.npmjs.com/package/ai-elements) is a component library and custom registry built on top of [shadcn/ui](https://ui.shadcn.com/) to help you build AI-native applications faster. It provides pre-built components like conversations, messages and more.

Installing AI Elements is straightforward and can be done in a couple of ways. You can use the dedicated CLI command for the fastest setup, or integrate via the standard shadcn/ui CLI if you've already adopted shadcn's workflow.



## Quick Start

Here are some basic examples of what you can achieve using components from AI Elements.



## Prerequisites

Before installing AI Elements, make sure your environment meets the following requirements:

- [Node.js](https://nodejs.org/en/download/), version 18 or later
- A [Next.js](https://nextjs.org/) project with the [AI SDK](https://ai-sdk.dev/) installed.
- [shadcn/ui](https://ui.shadcn.com/) installed in your project. If you don't have it installed, running any install command will automatically install it for you.
- We also highly recommend using the [AI Gateway](https://vercel.com/docs/ai-gateway) and adding `AI_GATEWAY_API_KEY` to your `env.local` so you don't have to use an API key from every provider. AI Gateway also gives $5 in usage per month so you can experiment with models. You can obtain an API key [here](https://vercel.com/d?to=%2F%5Bteam%5D%2F%7E%2Fai%2Fapi-keys&title=Get%20your%20AI%20Gateway%20key).



## Installing Components

You can install AI Elements components using either the AI Elements CLI or the shadcn/ui CLI. Both achieve the same result: adding the selected component’s code and any needed dependencies to your project.

The CLI will download the component’s code and integrate it into your project’s directory (usually under your components folder). By default, AI Elements components are added to the `@/components/ai-elements/` directory (or whatever folder you’ve configured in your shadcn components settings).

After running the command, you should see a confirmation in your terminal that the files were added. You can then proceed to use the component in your code.

## Usage

Once an AI Elements component is installed, you can import it and use it in your application like any other React component. The components are added as part of your codebase (not hidden in a library), so the usage feels very natural.

## Example

After installing AI Elements components, you can use them in your application like any other React component. For example:

```tsx title="conversation.tsx"
"use client";

import {
  Message,
  MessageContent,
  MessageResponse,
} from "@/components/ai-elements/message";
import { useChat } from "@ai-sdk/react";

const Example = () => {
  const { messages } = useChat();

  return (
    <>
      {messages.map(({ role, parts }, index) => (
        <Message from={role} key={index}>
          <MessageContent>
            {parts.map((part, i) => {
              switch (part.type) {
                case "text":
                  return (
                    <MessageResponse key={`${role}-${i}`}>
                      {part.text}
                    </MessageResponse>
                  );
              }
            })}
          </MessageContent>
        </Message>
      ))}
    </>
  );
};

export default Example;
```

In the example above, we import the `Message` component from our AI Elements directory and include it in our JSX. Then, we compose the component with the `MessageContent` and `MessageResponse` subcomponents. You can style or configure the component just as you would if you wrote it yourself – since the code lives in your project, you can even open the component file to see how it works or make custom modifications.

## Extensibility

All AI Elements components take as many primitive attributes as possible. For example, the `Message` component extends `HTMLAttributes<HTMLDivElement>`, so you can pass any props that a `div` supports. This makes it easy to extend the component with your own styles or functionality.

## Customization



After installation, no additional setup is needed. The component’s styles (Tailwind CSS classes) and scripts are already integrated. You can start interacting with the component in your app immediately.

For example, if you'd like to remove the rounding on `Message`, you can go to `components/ai-elements/message.tsx` and remove `rounded-lg` as follows:

```tsx title="components/ai-elements/message.tsx" highlight="8"
export const MessageContent = ({
  children,
  className,
  ...props
}: MessageContentProps) => (
  <div
    className={cn(
      "flex flex-col gap-2 text-sm text-foreground",
      "group-[.is-user]:bg-primary group-[.is-user]:text-primary-foreground group-[.is-user]:px-4 group-[.is-user]:py-3",
      className
    )}
    {...props}
  >
    <div className="is-user:dark">{children}</div>
  </div>
);
```

## Troubleshooting

## Why are my components not styled?

Make sure your project is configured correctly for shadcn/ui in Tailwind 4 - this means having a `globals.css` file that imports Tailwind and includes the shadcn/ui base styles.

## I ran the AI Elements CLI but nothing was added to my project

Double-check that:

- Your current working directory is the root of your project (where `package.json` lives).
- Your components.json file (if using shadcn-style config) is set up correctly.
- You’re using the latest version of the AI Elements CLI:

```bash title="Terminal"
npx ai-elements@latest
```

If all else fails, feel free to open an [issue on GitHub](https://github.com/vercel/ai-elements/issues).

## Theme switching doesn’t work — my app stays in light mode

Ensure your app is using the same data-theme system that shadcn/ui and AI Elements expect. The default implementation toggles a data-theme attribute on the `<html>` element. Make sure your tailwind.config.js is using class or data- selectors accordingly:

## The component imports fail with “module not found”

Check the file exists. If it does, make sure your `tsconfig.json` has a proper paths alias for `@/` i.e.

```json title="tsconfig.json"
{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "@/*": ["./*"]
    }
  }
}
```

## My AI coding assistant can't access AI Elements components

1. Verify your config file syntax is valid JSON.
2. Check that the file path is correct for your AI tool.
3. Restart your coding assistant after making changes.
4. Ensure you have a stable internet connection.

## Still stuck?

Overview

This skill helps you add new UI components to the ai-elements library following established composable patterns, shadcn/ui conventions, and the Vercel AI SDK structure. It guides creation of TypeScript React components under packages/elements/src and ensures consistent API, styling, and registry integration. Use it to extend AI Elements with new conversation UI, message parts, or utility widgets that plug into existing tooling.

How this skill works

The skill inspects the target folder and project configuration to generate component files, TypeScript types, and accompanying exports that follow ai-elements patterns. It wires components into the custom registry, adds shadcn/ui-compatible Tailwind classes, and includes Vercel AI SDK hooks or prop typings when relevant. Generated code is local to your components folder so you can iterate and customize immediately.

When to use it

  • You need a new chat UI component (Message, MessageContent, etc.) that composes with existing elements.
  • Adding a provider-specific input, attachment, or control that integrates with useChat or the AI SDK.
  • Creating small, reusable primitives that extend the ai-elements registry.
  • Migrating a bespoke UI piece into the ai-elements patterns for consistent styling and props.
  • Onboarding a new UI element that should be discoverable by the ai-elements CLI or registry.

Best practices

  • Follow existing component prop patterns (extend HTMLAttributes where possible) for composability and forwardRef compatibility.
  • Keep styling in Tailwind classes and mirror shadcn/ui utility patterns to ensure theme and data-theme compatibility.
  • Generate clear, minimal TypeScript types and export subcomponents alongside the main component for composition.
  • Register the component in the local registry index so CLI and consumers can discover it.
  • Include small usage examples and a brief doc comment in the component file for maintainability.

Example use cases

  • Create a threaded reply component that composes with Message and MessageContent.
  • Add a file-attachment UI that integrates with useChat uploads and includes progressive UI states.
  • Build a compact system prompt editor component that plugs into the AI SDK workflow.
  • Add a streaming response renderer component that consumes SDK message parts and renders markdown or code blocks.
  • Introduce an input toolbar with provider selector and quick prompts wired to the ai-elements registry.

FAQ

Will the skill modify my project files directly?

Yes. Generated components are added to your project under the configured components path so you can edit them directly.

Does it add runtime dependencies automatically?

It may add small helper imports and ensure shadcn/ui compatibility, but major dependencies should be installed via your package manager; the CLI can prompt when required.
