Re:Ask HN: How do you employ LLMs for UI development?

I’ve been using v0.dev (by Vercel) alongside Claude 3.5 Sonnet to build out the UI for my project, Dollarland (dollar-land.vercel.app).
The 'LLM + Shadcn/UI' workflow is the most productive I’ve found. I usually have Claude handle the complex state logic and business rules, then I pipe the requirements into v0 to generate the actual React components. It bridges that 'UX gap' by providing a visual starting point that isn't just a wall of code.
For a community-focused site like a forum, getting the 'vibe' and layout right is harder for LLMs than the logic, so I find that iterative prompting in a visual tool works better than pure code generation.
