# AI App Generator

Build full-stack AI applications with Next.js, AI SDK, and ai-elements.

## Quick Start

### 1. Scaffold Project

```bash
bunx --bun shadcn@latest create --preset "https://ui.shadcn.com/init?base=radix&style=nova&baseColor=neutral&theme=neutral&iconLibrary=lucide&font=geist-sans&menuAccent=subtle&menuColor=default&radius=default" --template next my-ai-app
cd my-ai-app
```

### 2. Install Dependencies

```bash
bun add ai @ai-sdk/react @ai-sdk/anthropic zod
bunx --bun ai-elements@latest
```

### 3. Configure Environment

```bash
# .env.local - Choose your provider
ANTHROPIC_API_KEY=sk-ant-...
# OPENAI_API_KEY=sk-...
# GOOGLE_GENERATIVE_AI_API_KEY=...
```

### 4. Generate Application

Based on user requirements, generate:
- **Chatbot**: See [references/chatbot.md](references/chatbot.md)
- **Agent Dashboard**: See [references/agent-dashboard.md](references/agent-dashboard.md)
- **Custom**: Combine patterns as needed

## Application Types

### Chatbot

Simple conversational AI with streaming responses.

| Feature | Implementation |
|---------|----------------|
| Chat UI | Conversation + Message + PromptInput |
| API | streamText + toUIMessageStreamResponse |
| Extras | Reasoning, Sources, File attachments |

### Agent Dashboard

Multi-agent interface with tool visualization.

| Feature | Implementation |
|---------|----------------|
| Agents | ToolLoopAgent with tools |
| UI | Dashboard layout + Tool components |
| API | createAgentUIStreamResponse |
| Extras | Status monitoring, tool approval |

### Custom AI App

Mix and match based on user needs:
- Web search chatbot
- Code generation assistant
- Document analyzer
- Multi-modal chat

## Core Patterns

### API Route

```typescript
// app/api/chat/route.ts
import { streamText, UIMessage, convertToModelMessages } from 'ai';
import { anthropic } from '@ai-sdk/anthropic';

export const maxDuration = 30;

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

  const result = streamText({
    model: anthropic('claude-sonnet-4-6'),
    messages: await convertToModelMessages(messages),
    system: 'You are a helpful assistant.',
  });

  return result.toUIMessageStreamResponse({
    sendSources: true,
    sendReasoning: true,
  });
}
```

### Chat Page

```tsx
// app/page.tsx
'use client';
import { useChat } from '@ai-sdk/react';
import { DefaultChatTransport } from 'ai';
import {
  Conversation,
  ConversationContent,
  ConversationScrollButton,
} from '@/components/ai-elements/conversation';
import {
  Message,
  MessageContent,
  MessageResponse,
} from '@/components/ai-elements/message';
import {
  PromptInput,
  PromptInputBody,
  PromptInputTextarea,
  PromptInputFooter,
  PromptInputSubmit,
  type PromptInputMessage,
} from '@/components/ai-elements/prompt-input';
import { Loader } from '@/components/ai-elements/loader';
import { useState } from 'react';

export default function ChatPage() {
  const [input, setInput] = useState('');
  const { messages, sendMessage, status } = useChat({
    transport: new DefaultChatTransport({ api: '/api/chat' }),
  });

  const handleSubmit = (message: PromptInputMessage) => {
    if (!message.text.trim()) return;
    sendMessage({ text: message.text, files: message.files });
    setInput('');
  };

  return (
    <div className="flex h-screen flex-col p-4">
      <Conversation className="flex-1">
        <ConversationContent>
          {messages.map((message) => (
            <div key={message.id}>
              {message.parts.map((part, i) => {
                if (part.type === 'text') {
                  return (
                    <Message key={i} from={message.role}>
                      <MessageContent>
                        <MessageResponse>{part.text}</MessageResponse>
                      </MessageContent>
                    </Message>
                  );
                }
                return null;
              })}
            </div>
          ))}
          {status === 'submitted' && <Loader />}
        </ConversationContent>
        <ConversationScrollButton />
      </Conversation>

      <PromptInput onSubmit={handleSubmit} className="mt-4">
        <PromptInputBody>
          <PromptInputTextarea
            value={input}
            onChange={(e) => setInput(e.target.value)}
          />
        </PromptInputBody>
        <PromptInputFooter>
          <div />
          <PromptInputSubmit status={status} />
        </PromptInputFooter>
      </PromptInput>
    </div>
  );
}
```

## Workflow

### Phase 1: Understand Requirements

Ask user:
- What type of AI app? (chatbot, agent, custom)
- What features? (reasoning, sources, tools, file upload)
- What style? (vega=classic, nova=compact, maia=soft/rounded, lyra=boxy/sharp, mira=dense) — default: nova
- What font? (geist-sans, inter, jetbrains-mono, figtree, dm-sans, outfit, noto-sans, nunito-sans, roboto, raleway, public-sans) — default: geist-sans
- What base color? (neutral, zinc, slate, gray, stone) — default: neutral
- What theme accent? (neutral, blue, green, orange, red, rose, violet) — default: neutral
- What border radius style? (default, sm, md, lg, xl)
- Component library? (radix=default, base-ui)

### Phase 2: Scaffold Project

Run scaffolding commands based on requirements.

### Phase 3: Generate Files

Create files based on application type:
- API route (`app/api/chat/route.ts`)
- Main page (`app/page.tsx`)
- Components (if needed)
- Agents (if needed)

### Phase 4: Configure

- Set up `.env.local`
- Configure `next.config.ts` if needed
- Add any additional dependencies

### Phase 5: Verify

```bash
bun dev
```

Test the application works correctly.

## Package Manager

**Always use bun**, never npm:
- `bun add` (not npm install)
- `bunx --bun` (not npx)
- `bun dev` (not npm run dev)
