Hunna just launched on Product Hunt and it's getting developer attention. Every successful Product Hunt launch teaches us the same lesson: apps with AI generation features win.

This tutorial shows how to add AI superpowers — personalized onboarding images, voice notifications, feature thumbnails, and video demos — to any app using NexaAPI.

client = NexaAPI(api_key='YOUR_API_KEY')

def generate_onboarding_image(app_name: str, user_name: str) -> str:
    """Generate a personalized onboarding image — $0.003"""
    result = client.image.generate(
        model='flux-schnell',
        prompt=f'Welcome screen for {app_name}, personalized for {user_name}, modern UI, warm colors',
        width=1024,
        height=768
    )
    return result.image_url

def generate_voice_notification(message: str) -> str:
    """Generate a TTS voice notification"""
    result = client.audio.tts(text=message, voice='en-US-neural')
    with open('notification.mp3', 'wb') as f:
        f.write(result.audio_bytes)
    return 'notification.mp3'

def generate_feature_thumbnail(feature: str) -> str:
    """Generate a feature thumbnail"""
    result = client.image.generate(
        model='flux-schnell',
        prompt=f'App feature icon for "{feature}", flat design, gradient, modern',
        width=512,
        height=512
    )
    return result.image_url

# Add AI to your app
img = generate_onboarding_image('MyApp', 'Sarah')
print(f'✅ Onboarding: {img} — $0.003')

audio = generate_voice_notification('Welcome to MyApp! Your account is ready.')
print(f'✅ Voice notification: {audio}')

thumb = generate_feature_thumbnail('Smart Analytics')
print(f'✅ Feature thumbnail: {thumb}')
