AI Elements

AI Elements is a comprehensive React component library for building AI-powered user interfaces. The library provides 30+ components specifically designed for chat interfaces, tool execution visualization, reasoning displays, and workflow management.

Installation

Install via shadcn registry:

npx shadcn@latest add https://ai-elements.vercel.app/r/[component-name]

Import Pattern : Components are imported from individual files, not a barrel export:

// Correct - import from specific files
import { Conversation } from "@/components/ai-elements/conversation";
import { Message } from "@/components/ai-elements/message";
import { PromptInput } from "@/components/ai-elements/prompt-input";

// Incorrect - no barrel export
import { Conversation, Message } from "@/components/ai-elements";

Component Categories

Conversation Components

Components for displaying chat-style interfaces with messages, attachments, and auto-scrolling behavior.

• Conversation : Container with auto-scroll capabilities
• Message : Individual message display with role-based styling
• MessageAttachment : File and image attachments
• MessageBranch : Alternative response navigation

See references/conversation.md for details.

Prompt Input Components

Advanced text input with file attachments, drag-and-drop, speech input, and state management.

• PromptInput : Form container with file handling
• PromptInputTextarea : Auto-expanding textarea
• PromptInputSubmit : Status-aware submit button
• PromptInputAttachments : File attachment display
• PromptInputProvider : Global state management

See references/prompt-input.md for details.

Workflow Components

Components for displaying job queues, tool execution, and approval workflows.

• Queue : Job queue container
• QueueItem : Individual queue items with status
• Tool : Tool execution display with collapsible states
• Confirmation : Approval workflow component
• Reasoning : Collapsible thinking/reasoning display

See references/workflow.md for details.

Visualization Components

ReactFlow-based components for workflow visualization and custom node types.

• Canvas : ReactFlow wrapper with aviation-specific defaults
• Node : Custom node component with handles
• Edge : Temporary and Animated edge types
• Controls, Panel, Toolbar : Navigation and control elements

See references/visualization.md for details.

Integration with shadcn/ui

AI Elements is built on top of shadcn/ui and integrates seamlessly with its theming system:

• Uses shadcn/ui's design tokens (colors, spacing, typography)
• Respects light/dark mode via CSS variables
• Compatible with shadcn/ui components (Button, Card, Collapsible, etc.)
• Follows shadcn/ui's component composition patterns

Key Design Patterns

Component Composition

AI Elements follows a composition-first approach where larger components are built from smaller primitives:

<Tool>
  <ToolHeader title="search" type="tool-call-search" state="output-available" />
  <ToolContent>
    <ToolInput input={{ query: "AI tools" }} />
    <ToolOutput output={results} errorText={undefined} />
  </ToolContent>
</Tool>

Context-Based State

Many components use React Context for state management:

• PromptInputProvider for global input state
• MessageBranch for alternative response navigation
• Confirmation for approval workflow state
• Reasoning for collapsible thinking state

Controlled vs Uncontrolled

Components support both controlled and uncontrolled patterns:

// Uncontrolled (self-managed state)
<PromptInput onSubmit={handleSubmit} />

// Controlled (external state)
<PromptInputProvider initialInput="">
  <PromptInput onSubmit={handleSubmit} />
</PromptInputProvider>

Tool State Machine

The Tool component follows the Vercel AI SDK's state machine:

1. input-streaming: Parameters being received
2. input-available: Ready to execute
3. approval-requested: Awaiting user approval (SDK v6)
4. approval-responded: User responded (SDK v6)
5. output-available: Execution completed
6. output-error: Execution failed
7. output-denied: Approval denied

Queue Patterns

Queue components support hierarchical organization:

<Queue>
  <QueueSection defaultOpen={true}>
    <QueueSectionTrigger>
      <QueueSectionLabel count={3} label="tasks" icon={<Icon />} />
    </QueueSectionTrigger>
    <QueueSectionContent>
      <QueueList>
        <QueueItem>
          <QueueItemIndicator completed={false} />
          <QueueItemContent>Task description</QueueItemContent>
        </QueueItem>
      </QueueList>
    </QueueSectionContent>
  </QueueSection>
</Queue>

Auto-Scroll Behavior

The Conversation component uses the use-stick-to-bottom hook for intelligent auto-scrolling:

• Automatically scrolls to bottom when new messages arrive
• Pauses auto-scroll when user scrolls up
• Provides scroll-to-bottom button when not at bottom
• Supports smooth and instant scroll modes

File Attachment Handling

PromptInput provides comprehensive file handling:

• Drag-and-drop support (local or global)
• Paste image/file support
• File type validation (accept prop)
• File size limits (maxFileSize prop)
• Maximum file count (maxFiles prop)
• Preview for images, icons for files
• Automatic blob URL to data URL conversion on submit

Speech Input

The PromptInputSpeechButton uses the Web Speech API for voice input:

• Browser-based speech recognition
• Continuous recognition mode
• Interim results support
• Automatic text insertion into textarea
• Visual feedback during recording

Reasoning Auto-Collapse

The Reasoning component provides auto-collapse behavior:

• Opens automatically when streaming starts
• Closes 1 second after streaming ends
• Tracks thinking duration in seconds
• Displays "Thinking..." with shimmer effect during streaming
• Shows "Thought for N seconds" when complete

TypeScript Types

All components are fully typed with TypeScript:

import type { ToolUIPart, FileUIPart, UIMessage } from "ai";

type ToolProps = ComponentProps<typeof Collapsible>;
type QueueItemProps = ComponentProps<"li">;
type MessageAttachmentProps = HTMLAttributes<HTMLDivElement> & {
  data: FileUIPart;
  onRemove?: () => void;
};

Common Use Cases

Chat Interface

Combine Conversation, Message, and PromptInput for a complete chat UI:

import { Conversation, ConversationContent, ConversationScrollButton } from "@/components/ai-elements/conversation";
import { Message, MessageContent, MessageResponse } from "@/components/ai-elements/message";
import {
  PromptInput,
  PromptInputTextarea,
  PromptInputFooter,
  PromptInputTools,
  PromptInputButton,
  PromptInputSubmit
} from "@/components/ai-elements/prompt-input";

<div className="flex flex-col h-screen">
  <Conversation>
    <ConversationContent>
      {messages.map(msg => (
        <Message key={msg.id} from={msg.role}>
          <MessageContent>
            <MessageResponse>{msg.content}</MessageResponse>
          </MessageContent>
        </Message>
      ))}
    </ConversationContent>
    <ConversationScrollButton />
  </Conversation>

  <PromptInput onSubmit={handleSubmit}>
    <PromptInputTextarea />
    <PromptInputFooter>
      <PromptInputTools>
        <PromptInputButton onClick={() => attachments.openFileDialog()}>
          <PaperclipIcon />
        </PromptInputButton>
      </PromptInputTools>
      <PromptInputSubmit status={chatStatus} />
    </PromptInputFooter>
  </PromptInput>
</div>

Tool Execution Display

Show tool execution with expandable details:

import { Tool, ToolHeader, ToolContent, ToolInput, ToolOutput } from "@/components/ai-elements/tool";

{toolInvocations.map(tool => (
  <Tool key={tool.id}>
    <ToolHeader
      title={tool.toolName}
      type={`tool-call-${tool.toolName}`}
      state={tool.state}
    />
    <ToolContent>
      <ToolInput input={tool.args} />
      {tool.result && (
        <ToolOutput output={tool.result} errorText={tool.error} />
      )}
    </ToolContent>
  </Tool>
))}

Approval Workflow

Request user confirmation before executing actions:

import {
  Confirmation,
  ConfirmationTitle,
  ConfirmationRequest,
  ConfirmationActions,

  ConfirmationAccepted,
  ConfirmationRejected
} from "@/components/ai-elements/confirmation";

<Confirmation approval={tool.approval} state={tool.state}>
  <ConfirmationTitle>
    Approve deletion of {resource}?
  </ConfirmationTitle>

  <ConfirmationRequest>
    <ConfirmationActions>
      <ConfirmationAction onClick={approve} variant="default">
        Approve
      </ConfirmationAction>
      <ConfirmationAction onClick={reject} variant="outline">
        Reject
      </ConfirmationAction>
    </ConfirmationActions>
  </ConfirmationRequest>

  <ConfirmationAccepted>
    Action approved and executed.
  </ConfirmationAccepted>

  <ConfirmationRejected>
    Action rejected.
  </ConfirmationRejected>
</Confirmation>

Job Queue Management

Display task lists with completion status:

import {
  Queue,
  QueueSection,
  QueueSectionTrigger,
  QueueSectionLabel,
  QueueSectionContent,
  QueueList,
  QueueItem,
  QueueItemIndicator,
  QueueItemContent,
  QueueItemDescription
} from "@/components/ai-elements/queue";

<Queue>
  <QueueSection>
    <QueueSectionTrigger>
      <QueueSectionLabel count={todos.length} label="todos" />
    </QueueSectionTrigger>
    <QueueSectionContent>
      <QueueList>
        {todos.map(todo => (
          <QueueItem key={todo.id}>
            <QueueItemIndicator completed={todo.status === 'completed'} />
            <QueueItemContent completed={todo.status === 'completed'}>
              {todo.title}
            </QueueItemContent>
            {todo.description && (
              <QueueItemDescription completed={todo.status === 'completed'}>
                {todo.description}
              </QueueItemDescription>
            )}
          </QueueItem>
        ))}
