AI Elements Chatbot Components

Status: Production Ready Last Updated: 2025-11-07 Dependencies: tailwind-v4-shadcn (prerequisite), ai-sdk-ui (companion), nextjs (framework) Latest Versions: ai-elements@1.6.0, ai@5.0+, next@15+, react@19+

---

Quick Start (15 Minutes)

1. Verify Prerequisites

Before installing AI Elements, ensure these are already set up:

# Check Next.js version (needs 15+)
npx next --version

# Check AI SDK version (needs 5+)
npm list ai

# Check shadcn/ui is initialized
ls components/ui  # Should exist with button.tsx etc

Why this matters:

• AI Elements is built ON TOP of shadcn/ui (won't work without it)
• Requires Next.js App Router (Pages Router not supported)
• AI SDK v5 has breaking changes from v4

Missing prerequisites? Use the tailwind-v4-shadcn skill first, then install AI SDK:

pnpm add ai@latest

2. Install AI Elements CLI

# Initialize AI Elements in your project
pnpm dlx ai-elements@latest init

# Add your first components
pnpm dlx ai-elements@latest add message conversation response prompt-input

CRITICAL:

• Components are copied into components/ui/ai/ (NOT installed as npm package)
• Full source code ownership (modify as needed)
• Registry URL must be correct in components.json

3. Create Basic Chat Interface

// app/chat/page.tsx
'use client';

import { useChat } from 'ai/react';
import { Conversation } from '@/components/ui/ai/conversation';
import { Message } from '@/components/ui/ai/message';
import { MessageContent } from '@/components/ui/ai/message-content';
import { Response } from '@/components/ui/ai/response';
import { PromptInput } from '@/components/ui/ai/prompt-input';

export default function ChatPage() {
  const { messages, input, handleInputChange, handleSubmit, isLoading } = useChat({
    api: '/api/chat'
  });

  return (
    <div className="flex h-screen flex-col">
      <Conversation className="flex-1">
        {messages.map((msg) => (
          <Message key={msg.id} role={msg.role}>
            <MessageContent>
              <Response markdown={msg.content} />
            </MessageContent>
          </Message>
        ))}
      </Conversation>

      <PromptInput
        value={input}
        onChange={handleInputChange}
        onSubmit={handleSubmit}
        disabled={isLoading}
      />
    </div>
  );
}

Done! You now have a working chat interface with:

• ✅ Streaming markdown rendering
• ✅ Auto-scrolling conversation
• ✅ Auto-resizing input
• ✅ Role-based message styling

---

The 5-Step Setup Process

Step 1: Install AI Elements CLI

pnpm dlx ai-elements@latest init

This:

• Creates components/ui/ai/ directory
• Updates components.json with AI Elements registry
• Adds necessary dependencies to package.json

Key Points:

• Run from project root (where package.json is)
• Requires shadcn/ui already initialized
• Will fail if components.json missing (run pnpm dlx shadcn@latest init first)

Step 2: Add Core Chat Components

# Essential components for basic chat
pnpm dlx ai-elements@latest add message message-content conversation response

# Optional: Input component
pnpm dlx ai-elements@latest add prompt-input actions suggestion

Component Purpose:

• message: Container for single message (user/AI)
• message-content: Wrapper for message parts
• conversation: Auto-scrolling chat container
• response: Markdown renderer (streaming-optimized)
• prompt-input: Auto-resizing textarea with toolbar
• actions: Copy/regenerate/edit buttons
• suggestion: Quick prompt pills

Step 3: Add Advanced Components (Optional)

# For tool calling
pnpm dlx ai-elements@latest add tool

# For reasoning display (Claude/o1 style)
pnpm dlx ai-elements@latest add reasoning

# For source citations (Perplexity style)
pnpm dlx ai-elements@latest add sources inline-citation

# For code highlighting
pnpm dlx ai-elements@latest add code-block

# For conversation branching
pnpm dlx ai-elements@latest add branch

# For task lists
pnpm dlx ai-elements@latest add task

# For AI-generated images
pnpm dlx ai-elements@latest add image

# For web previews (Claude artifacts style)
pnpm dlx ai-elements@latest add web-preview

# For loading states
pnpm dlx ai-elements@latest add loader

When to add each:

• tool: Building AI assistants with function calling
• reasoning: Showing AI's thinking process (like Claude or o1)
• sources: Adding citations and references (like Perplexity)
• code-block: Chat includes code snippets
• branch: Multi-turn conversations with variations
• task: AI generates task lists with file references
• image: AI generates images (DALL-E, Stable Diffusion)
• web-preview: AI generates HTML/websites (Claude artifacts)
• loader: Show loading states during streaming

Step 4: Create API Route

Create /app/api/chat/route.ts:

import { openai } from '@ai-sdk/openai';
import { streamText } from 'ai';

export async function POST(req: Request) {
  const { messages } = await req.json();

  const result = streamText({
    model: openai('gpt-4o'),
    messages,
  });

  return result.toDataStreamResponse();
}

Key Points:

• Must use AI SDK v5 streamText() (not v4 OpenAIStream())
• Returns toDataStreamResponse() for streaming
• Client auto-receives updates via useChat() hook

Step 5: Verify Installation

# Check components installed
ls components/ui/ai/

# Expected output:
# message.tsx, message-content.tsx, conversation.tsx, response.tsx, prompt-input.tsx, ...

# Start dev server
pnpm dev

# Test chat interface at http://localhost:3000/chat

Verification Checklist:

• All components in components/ui/ai/
• components.json has AI Elements registry
• No TypeScript errors
• Chat interface renders
• Streaming works (type message → get response)
• Auto-scroll works during streaming

Critical Rules

Always Do

✅ Initialize shadcn/ui BEFORE AI Elements - AI Elements requires shadcn/ui as foundation ✅ Use AI SDK v5 - v4 is incompatible (breaking changes) ✅ Use Next.js App Router - Pages Router not supported ✅ Wrap with 'use client' - All AI Elements components are client-side ✅ Pass raw markdown to Response component - Not pre-rendered HTML ✅ Use Conversation component as container - Handles auto-scroll and virtualization ✅ Conditionally show voice input - Only works in Chrome/Edge (not Firefox/Safari) ✅ Merge consecutive reasoning blocks - Prevent duplication in long responses

Never Do

❌ Install AI Elements as npm package - It's a CLI tool that copies components ❌ Use with AI SDK v4 - Will fail with type errors and data format issues ❌ Forget 'use client' directive - Components use React hooks (client-only) ❌ Mix with other component libraries - Built for shadcn/ui only (Tailwind classes) ❌ Manually write component code - Use CLI to ensure correct patterns ❌ Skip prerequisites check - Will fail silently with confusing errors ❌ Use in Pages Router - Requires App Router features ❌ Assume voice input works everywhere - Web Speech API is Chrome/Edge only

---

Known Issues Prevention

This skill prevents 8 documented issues:

Issue #1: PromptInputSpeechButton Not Working (Firefox/Safari)

Error: Voice input button doesn't respond or throws SpeechRecognition is not defined Source: https://github.com/vercel/ai-elements/issues/210 Why It Happens: Web Speech API only supported in Chromium browsers (Chrome, Edge) Prevention:

// Conditionally show voice button
const isSpeechSupported = typeof window !== 'undefined' &&
  ('webkitSpeechRecognition' in window || 'SpeechRecognition' in window);

<PromptInput
  enableSpeech={isSpeechSupported}
  // Fallback: Implement server-side STT (Whisper, Google Speech)
/>

Issue #2: PromptInput Not Responsive on Mobile

Error: Input overflows or doesn't resize properly on small screens Source: https://github.com/vercel/ai-elements/issues/153 Why It Happens: Missing responsive min-height constraints Prevention:

<PromptInput
  className="min-h-[100px] sm:min-h-[60px]"  // Add responsive classes
  // ... other props
/>

Issue #3: Multiple Thinking Elements in Long Responses

Error: Duplicate reasoning/thinking blocks appear instead of single merged block Source: https://github.com/vercel/ai-elements/issues/106 Why It Happens: Streaming creates separate components for each chunk Prevention:

// Merge reasoning chunks client-side
const processedMessages = messages.map(msg => {
  if (msg.annotations?.reasoning) {
    // Combine all reasoning into single string
    const merged = Array.isArray(msg.annotations.reasoning)
      ? msg.annotations.reasoning.join('\n\n')
      : msg.annotations.reasoning;
    return { ...msg, annotations: { ...msg.annotations, reasoning: merged } };
  }
  return msg;
});

Issue #4: Component Not Found After Installation

Error: Cannot find module '@/components/ui/ai/message' Source: Common user error Why It Happens: AI Elements not initialized or wrong registry URL Prevention:

# Verify components.json has correct registry
cat components.json | grep -A5 "ai-elements"

# Re-initialize if missing
pnpm dlx ai-elements@latest init

# Check components directory exists
ls components/ui/ai/

Issue #5: AI SDK v5 Breaking Changes

Error: Type errors, undefined properties, or streaming not working Source: https://sdk.vercel.ai/docs/ai-sdk-core/migration Why It Happens: v5 has breaking API changes from v4 Prevention:

// ✅ v5 (correct)
const { messages } = useChat();  // Direct messages array
msg.toolInvocations  // Tool calls here

// ❌ v4 (incorrect)
const { data } = useChat();  // Wrapped in data object
msg.tool_calls  // Different property name

Issue #6: Maximum Update Depth Exceeded

Error: React error "Maximum update depth exceeded" during streaming Source: https://github.com/vercel/ai-elements/issues/97 Why It Happens: Infinite re-render loop from unstable callbacks Prevention:

// Memoize callbacks to prevent re-renders
import { useCallback } from 'react';

const { messages } = useChat({
  api: '/api/chat',
  onFinish: useCallback((message) => {
    console.log('Finished', message);
  }, [])  // Stable dependency array
});

Issue #7: Copy Button Returns HTML Instead of Markdown

Error: Copying message pastes HTML instead of plain markdown Source: https://github.com/vercel/ai-elements/issues/180 Why It Happens: Actions.Copy uses innerHTML by default Prevention:

// Pass raw markdown content, not rendered HTML
<Actions>
  <Actions.Copy content={msg.content} format="markdown" />
</Actions>

Issue #8: Tailwind v4 CSS Variable Issues

Error: Components have no styling or broken colors Source: Common with Tailwind v4 migration Why It Happens: Missing CSS variables or wrong @theme configuration Prevention:

# Use tailwind-v4-shadcn skill to fix, or manually verify:

# Check src/index.css has:
@import "tailwindcss";

:root {
  --background: hsl(0 0% 100%);
  --foreground: hsl(0 0% 3.9%);
  /* ... other variables */
}

@theme inline {
  --color-background: var(--background);
  --color-foreground: var(--foreground);
}

Configuration Files Reference

components.json (AI Elements Registry)

{
  "$schema": "https://ui.shadcn.com/schema.json",
  "style": "new-york",
  "rsc": false,
  "tsx": true,
  "tailwind": {
    "config": "",
    "css": "src/index.css",
    "baseColor": "zinc",
    "cssVariables": true,
    "prefix": ""
  },
  "aliases": {
    "components": "@/components",
    "utils": "@/lib/utils",
    "ui": "@/components/ui",
    "lib": "@/lib",
    "hooks": "@/hooks"
  },
  "registries": {
    "shadcn": "https://ui.shadcn.com/registry",
    "ai-elements": "https://www.shadcn.io/ai/registry"
  }
}

Why these settings:

• "rsc": false - AI Elements are client components (not RSC compatible)
• "tsx": true - TypeScript required for type safety
• "tailwind.config": "" - Tailwind v4 doesn't use config file
• registries - Both shadcn and AI Elements registries needed

Common Patterns

Pattern 1: Basic Chat with Actions

'use client';

import { useChat } from 'ai/react';
import { Conversation, Message, MessageContent, Response, Actions } from '@/components/ui/ai';
import { PromptInput } from '@/components/ui/ai/prompt-input';

export default function ChatWithActions() {
  const { messages, input, handleInputChange, handleSubmit, reload, stop } = useChat();

  return (
    <div className="flex h-screen flex-col">
      <Conversation className="flex-1">
        {messages.map((msg) => (
          <Message key={msg.id} role={msg.role}>
            <MessageContent>
              <Response markdown={msg.content} />
              {msg.role === 'assistant' && (
                <Actions>
                  <Actions.Copy content={msg.content} />
                  <Actions.Regenerate onClick={() => reload()} />
                </Actions>
              )}
            </MessageContent>
          </Message>
        ))}
      </Conversation>

      <PromptInput
        value={input}
        onChange={handleInputChange}
        onSubmit={handleSubmit}
      />
    </div>
  );
}

When to use: Every chat interface (copy and regenerate are essential UX)

Pattern 2: Chat with Tool Calling

'use client';

import { useChat } from 'ai/react';
import { Tool } from '@/components/ui/ai/tool';
import { z } from 'zod';

export default function ChatWithTools() {
  const { messages } = useChat({
    api: '/api/chat',
    async onToolCall({ toolCall }) {
      if (toolCall.toolName === 'get_weather') {
        // Execute tool
        return { temperature: 72, conditions: 'Sunny' };
      }
    }
  });

  return (
    <Conversation>
      {messages.map((msg) => (
        <Message key={msg.id} role={msg.role}>
          <MessageContent>
            {msg.content && <Response markdown={msg.content} />}

            {/* Render tool invocations */}
            {msg.toolInvocations?.map((tool) => (
              <Tool
                key={tool.toolCallId}
                name={tool.toolName}
                args={tool.args}
                result={tool.result}
                status={tool.state}  // "pending" | "success" | "error"
              />
            ))}
          </MessageContent>
        </Message>
      ))}
    </Conversation>
  );
}

When to use: AI assistants with function calling (like ChatGPT with plugins)

Pattern 3: Chat with Reasoning Display

'use client';

import { useChat } from 'ai/react';
import { Reasoning } from '@/components/ui/ai/reasoning';

export default function ChatWithReasoning() {
  const { messages, isLoading } = useChat({
    api: '/api/chat',
    streamProtocol: 'text'
  });

  return (
    <Conversation>
      {messages.map((msg, idx) => {
        const reasoning = msg.annotations?.reasoning;
        const isStreaming = isLoading && idx === messages.length - 1;

        return (
          <Message key={msg.id} role={msg.role}>
            <MessageContent>
              {reasoning && (
                <Reasoning
                  content={reasoning}
                  streaming={isStreaming}
                  collapsed={!isStreaming}  // Collapse after done
                />
              )}
              <Response markdown={msg.content} />
            </MessageContent>
          </Message>
        );
      })}
    </Conversation>
  );
}

When to use: Claude-style thinking, o1-style reasoning, chain-of-thought prompting

Pattern 4: Chat with Source Citations

'use client';

import { useChat } from 'ai/react';
import { Sources, InlineCitation } from '@/components/ui/ai';

export default function ChatWithSources() {
  const { messages } = useChat({
    api: '/api/chat'
  });

  return (
    <Conversation>
      {messages.map((msg) => {
        const sources = msg.annotations?.sources || [];

        return (
          <Message key={msg.id} role={msg.role}>
            <MessageContent>
              <Response markdown={msg.content} />

              {/* Show sources at bottom */}
              {sources.length > 0 && (
                <Sources
                  sources={sources}
                  citations={msg.annotations?.citations || []}
                />
              )}
            </MessageContent>
          </Message>
        );
      })}
    </Conversation>
  );
}

When to use: RAG applications, Perplexity-style search, citation-backed responses

Pattern 5: Chat with Code Blocks

'use client';

import { useChat } from 'ai/react';
import { CodeBlock } from '@/components/ui/ai/code-block';
import { Response } from '@/components/ui/ai/response';

export default function ChatWithCode() {
  const { messages } = useChat();

  return (
    <Conversation>
      {messages.map((msg) => (
        <Message key={msg.id} role={msg.role}>
          <MessageContent>
            {/* Response component auto-renders code blocks */}
            <Response
              markdown={msg.content}
              components={{
                // Optionally override code rendering
                code: ({ language, code }) => (
                  <CodeBlock
                    language={language}
                    code={code}
                    showLineNumbers={true}
                  />
                )
              }}
            />
          </MessageContent>
        </Message>
      ))}
    </Conversation>
  );
}

When to use: Coding assistants, technical documentation chat, code review

Advanced Topics

Performance Optimization with Virtualization

For conversations with 100+ messages, use virtualization:

import { useVirtualizer } from '@tanstack/react-virtual';
import { useRef } from 'react';

function VirtualizedChat({ messages }) {
  const parentRef = useRef<HTMLDivElement>(null);

  const virtualizer = useVirtualizer({
    count: messages.length,
    getScrollElement: () => parentRef.current,
    estimateSize: () => 150,  // Average message height
    overscan: 5  // Render 5 extra items for smooth scrolling
  });

  return (
    <div ref={parentRef} className="h-screen overflow-y-auto">
      <div style={{ height: `${virtualizer.getTotalSize()}px`, position: 'relative' }}>
        {virtualizer.getVirtualItems().map((virtualRow) => (
          <div
            key={virtualRow.index}
            style={{
              position: 'absolute',
              top: 0,
              left: 0,
              width: '100%',
              height: `${virtualRow.size}px`,
              transform: `translateY(${virtualRow.start}px)`
            }}
          >
            <Message {...messages[virtualRow.index]} />
          </div>
        ))}
      </div>
    </div>
  );
}

When to use: Conversations exceeding 50-100 messages (improves rendering performance)

Custom Styling with CSS Variables

All components use semantic colors from shadcn/ui:

/* src/index.css - Customize AI message colors */

:root {
  /* AI message background */
  --ai-message: hsl(var(--muted));
  --ai-message-foreground: hsl(var(--muted-foreground));

  /* User message background */
  --user-message: hsl(var(--primary));
  --user-message-foreground: hsl(var(--primary-foreground));

  /* Tool call colors */
  --tool-success: hsl(142 76% 36%);
  --tool-error: hsl(var(--destructive));
  --tool-pending: hsl(47 91% 58%);
}

.dark {
  --ai-message: hsl(var(--muted));
  --ai-message-foreground: hsl(var(--muted-foreground));
  /* ... dark mode variants */
}

Accessibility Best Practices

AI Elements components follow WCAG 2.1 AA standards:

// Add ARIA labels to interactive elements
<PromptInput
  aria-label="Chat message input"
  aria-describedby="chat-instructions"
/>

<Actions>
  <Actions.Copy
    aria-label="Copy message to clipboard"
    aria-live="polite"  // Announce copy success
  />
  <Actions.Regenerate
    aria-label="Regenerate AI response"
  />
</Actions>

// Screen reader announcements for streaming
<Response
  markdown={content}
  aria-live="polite"  // Announce updates during streaming
  aria-atomic="false"  // Only announce changes, not entire content
/>

Server-Side Tool Execution

For secure tool calling, execute on server:

// app/api/chat/route.ts
import { openai } from '@ai-sdk/openai';
import { streamText, tool } from 'ai';
import { z } from 'zod';

export async function POST(req: Request) {
  const { messages } = await req.json();

  const result = streamText({
    model: openai('gpt-4o'),
    messages,
    tools: {
      get_weather: tool({
        description: 'Get current weather for a location',
        parameters: z.object({
          location: z.string().describe('City name'),
          unit: z.enum(['celsius', 'fahrenheit']).default('celsius')
        }),
        execute: async ({ location, unit }) => {
          // Execute server-side (secure API keys)
          const response = await fetch(`https://api.weather.com/...`);
          const data = await response.json();
          return { temperature: data.temp, conditions: data.conditions };
        }
      }),

      search_database: tool({
        description: 'Search internal database',
        parameters: z.object({
          query: z.string()
        }),
        execute: async ({ query }) => {
          // Direct database access (server-side only)
          const results = await db.search(query);
          return results;
        }
      })
    }
  });

  return result.toDataStreamResponse();
}

Benefits:

• Secure API keys (never exposed to client)
• Direct database access
• Rate limiting and validation
• Audit logging

Troubleshooting

Problem: Voice input button not working

Solution:

// Check browser support
const supported = 'webkitSpeechRecognition' in window;
console.log('Speech supported:', supported);  // false in Firefox/Safari

// Use only in supported browsers or implement server-side STT
<PromptInput enableSpeech={supported} />

Problem: Components not found after installation

Solution:

# Verify installation
ls components/ui/ai/  # Should show components

# Check registry in components.json
cat components.json | grep "ai-elements"

# Re-initialize if needed
pnpm dlx ai-elements@latest init
pnpm dlx ai-elements@latest add message conversation response

Problem: Streaming not working

Solution:

// API route MUST return toDataStreamResponse()
return result.toDataStreamResponse();  // ✅ Correct

// NOT:
return result.toTextStreamResponse();  // ❌ Wrong format for AI Elements

Problem: Styling broken or missing colors

Solution:

# Use tailwind-v4-shadcn skill to fix, or verify:
# 1. Check src/index.css has @import "tailwindcss" at top
# 2. Verify CSS variables defined in :root and .dark
# 3. Check @theme inline section exists
# 4. Ensure vite.config.ts has @tailwindcss/vite plugin
