[Bonus] Supercharge UI with Vercel v0

You've learned how to interact with LLMs using the AI SDK. That's great, but your users need an excellent UI. This is where v0 comes in. v0 turns text prompts into well structured, fully styled React components in seconds. From basic prototypes to full-featured applications deployed to the web, v0 quickly brings your UI vision into reality.

Go from text prompt to polished UI components without CSS hell. Get slick interfaces for your AI features without design skills.

What is Vercel v0?

v0 is a powerful application building agent that takes your natural language prompts and converts them into fully functioning deployable applications. Feed it a prompt, get back production-ready React code. It's trained on best practices for React, Tailwind and shadcn/ui.

v0 removes a lot of the initial pixel-pushing and CSS debugging, letting you focus on functionality.

Generate a Component with v0

Let's build a card component to show that structured appointment data from the last lesson.

Head to v0.app and try this prompt:

Create a React card component using Tailwind CSS and shadcn/ui Card components. It should accept props: title (string), date (string), time (string, nullable), location (string, nullable). Display title prominently. Show date/time and location below, each with a simple icon (calendar, clock, map pin). Handle null values gracefully with placeholder text like 'Not specified'.

Iterating on Prompts

Small tweaks in prompts can mean big UI changes and much quicker turn around from idea to deployment:

Weak Prompt:

Create an appointment card.

Strong Prompt:

Create a calendar appointment card using shadcn/ui Card component, with a blue background, white text, rounded corners, and slight hover effect.  Use this schema:  export const appointmentSchema = z.object({
  title: z.string(),
  // Use nullable() for fields that might not be present
  startTime: z.string().nullable(),
  endTime: z.string().nullable(),
  attendees: z.array(z.string()).nullable(),
  location: z.string().nullable(),
  // Date is required
  date: z.string(),
})

Giving v0 specific details will result in more refined output that is closer to what we want. Otherwise we make the LLM guess, and the results reflect that.

Give it a try yourself:

Try this prompt at v0.app:

Create a React card component using Tailwind CSS and shadcn/ui Card components. Props: title, date, time, location. Show title and details with icons.

Build and Integrate Your Own Component

Let's create a component specifically for displaying the structured data from our extraction lesson, then integrate it into your project.

Step 1: Generate Your Component with v0

Use this prompt at v0.app:

Create a SummaryCard React component using shadcn/ui Card components and Tailwind CSS.

Props interface:

• headline: string (main title, prominent display)
• context: string (background info, smaller text)
• discussionPoints: string (key topics, formatted as a list)
• takeaways: string (action items, formatted as bullets)

Design requirements:

• Clean card layout with subtle border and shadow
• Headline should be large and bold
• Use icons from lucide-react for each section (MessageSquare for context, List for discussion, CheckCircle for takeaways)
• Responsive design that works on mobile
• Light background with good contrast

Step 2: Copy the Generated Component

After v0 generates your component:

1. Copy the entire component code from v0
2. Note any dependencies listed (usually shadcn components and icons)

Step 3: Set Up Dependencies

Check what shadcn components you need and install them:

# Common components you might need (overwrite existing if prompted)
pnpm dlx shadcn@latest add card
pnpm dlx shadcn@latest add badge

# Install lucide-react
pnpm add lucide-react

Step 4: Create the Component File

Create components/SummaryCard.tsx and paste your v0-generated code:

// TODO: Paste your v0-generated component code here
// Make sure to include all imports at the top

interface SummaryCardProps {
  headline: string;
  context: string;
  discussionPoints: string;
  takeaways: string;
}

export function SummaryCard({ headline, context, discussionPoints, takeaways }: SummaryCardProps) {
  // TODO: Paste the component JSX from v0 here
  return (
    <div>Your v0 component goes here</div>
  );
}

Step 5: Test Integration

Replace the existing SummaryCard in your summarization page with your new v0-generated component:

// Update the import to use your new component
import { SummaryCard } from '@/components/SummaryCard';

// The rest of your code remains the same

Step 6: Verify It Works

1. Run your dev server: pnpm dev
2. Navigate to: http://localhost:3000/summarization
3. Click "Summarize" and see your custom v0 component in action!

Integrating v0 Code

The code v0 creates is ready to ship. You can often just cut and paste into your app. Here's how to use it:

1. Copy Code: Grab everything including imports
2. Install Dependencies: Often this means shadcn components, which are added like this:

# Example if Card
pnpm dlx shadcn@latest add card

3. Create Component File: Drop it in components/GeneratedCard.tsx
4. Import & Use: Pass your data to the new component

Example Generated Code (Simplified, your code will vary):

// components/GeneratedCard.tsx
import { CalendarIcon, ClockIcon, MapPinIcon } from 'lucide-react' // Ensure lucide-react is installed

interface GeneratedCardProps {
	title: string
	date: string
	time?: string | null
	location?: string | null
}

export function GeneratedCard({ title, date, time, location }: GeneratedCardProps) {
	return (
		<Card>
			<CardHeader>
				<CardTitle>{title}</CardTitle>
			</CardHeader>
			<CardContent className="space-y-2 text-sm">
				<div className="flex items-center gap-2">
					<CalendarIcon className="size-4 text-muted-foreground" />
					<span>{date}</span>
					{time && (
						<>
							<ClockIcon className="size-4 text-muted-foreground ml-2" />
							<span>{time}</span>
						</>
					)}
					{!time && <span className="text-muted-foreground">(Time not specified)</span>}
				</div>
				<div className="flex items-center gap-2">
					<MapPinIcon className="size-4 text-muted-foreground" />
					<span>
						{location || <span className="text-muted-foreground">Location not specified</span>}
					</span>
				</div>
			</CardContent>
		</Card>
	)
}

Using it:

// Example usage in a page component

export default function MyPage() {
	const appointmentData = {
		// Example data
		title: 'AI Sync Meeting',
		date: '2025-11-15',
		time: '14:00',
		location: 'Virtual',
	}

	return (
		<div>
			<h1>Upcoming Appointment</h1>
			<GeneratedCard {...appointmentData} />
		</div>
	)
}

With v0, you can:

• Create beautiful UIs for your AI outputs
• Iterate on design through text instead of CSS

Key Takeaways

• UI-as-Prompts: Tell v0 what you want, get polished React components
• Ship Faster: Cut UI dev time by 80%+, focus on AI SDK for low-level heavy lifting
• Dead Simple: Copy, paste, add dependencies, import, done
• Perfect for AI Results: Quickly create cards/displays for your AI data

It's the speed combo: AI SDK handles the brains, v0 handles the looks. Cuts the UI boilerplate you are required to create by hand dramatically.
