主な機能

• Collaborative AI assistant for designing, iterating, and scaling web apps.
• Generates UI, websites, and full-stack application starting points.
• Strong fit for React, Next.js, Tailwind, shadcn/ui, and Vercel deployment workflows.
• Can turn prompts, screenshots, and design ideas into editable app code.
• Useful for rapid prototyping, product demos, landing pages, and internal tools.

実務ユースケース

• Generate a polished landing page or dashboard from a text brief.
• Turn a rough product idea into a clickable React/Next.js prototype.
• Iterate UI states, layout, copy, and components with a designer or founder.
• Create internal tools and admin screens before engineering hardens the backend.
• Export or adapt generated code into a Vercel-centered development workflow.

推奨ワークフロー

• Start with a specific product brief, audience, pages, and UI states.
• Ask for small iterations rather than one large app rewrite.
• Review generated code for accessibility, responsiveness, data flow, and security.
• Connect real APIs and auth only after the UI concept is stable.
• Use Vercel deployment and code review before production release.

強みと注意点

• Excellent for fast web UI and app prototypes.
• Best output comes from precise prompts and iterative review.
• Generated apps still need engineering hardening for auth, data security, business logic, and tests.
• Not a replacement for product design judgment or production architecture.

比較候補

• Cursor for editing an existing codebase in an AI IDE.
• Lovable for full app generation with a broader no-code feel.
• Replit Agent for cloud coding and deployment workflows.
• Framer or Webflow for visual website building.
