• Install Vercel CLI
• Run "vercel" command in project directory
• App goes live in minutes!

7) Taking it further:
• Build iOS apps from webbased prototypes
• Explore more advanced tools like Pipecat for greater control
• Consider creating VTuberstyle experiences

8) Key takeaways:
• Start small, build incrementally
• Leverage existing demos and tools
• Focus on creating viralworthy moments
• The future of apps = AI characters!
