AI Elements

AI Elements is a component library and custom registry built on top of shadcn/ui 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, version 18 or later
• A Next.js project with the AI SDK installed.
• shadcn/ui installed in your project. If you don't have it installed, running any install command will automatically install it for you.

Installing Components

Install AI Elements components using either the dedicated AI Elements CLI or the shadcn/ui CLI. Both achieve the same result: adding the selected component's code and any needed dependencies to the project.

AI Elements CLI

# npm
npx ai-elements@latest add message
# pnpm
pnpm dlx ai-elements@latest add message
# yarn
yarn dlx ai-elements@latest add message
# bun
bun x ai-elements@latest add message

shadcn CLI

# npm
npx shadcn@latest add @ai-elements/message
# pnpm
pnpm dlx shadcn@latest add @ai-elements/message
# yarn
yarn dlx shadcn@latest add @ai-elements/message
# bun
bun x shadcn@latest add @ai-elements/message

The CLI downloads the component's code and integrates it into the project's directory. By default, AI Elements components are added to @/components/ai-elements/ (or whatever folder is configured in components.json). After running the command, the terminal confirms which files were added — proceed to import and use the component in 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:

"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;

The example above imports the Message component from the AI Elements directory and composes it with the MessageContent and MessageResponse subcomponents. Style or configure the component just as you would any local component — since the code lives in your project, the component file can be opened directly for inspection or 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:

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 by passing @latest and a component name:

bun x ai-elements@latest add message
# or:
npx ai-elements@latest add message

If all else fails, feel free to open an issue on GitHub.

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.

{
  "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.
