PromptUI turns plain English into production-ready UI code. Describe what you want, and it generates the HTML, CSS, and optionally React components to build it. This article walks through a real example — from initial prompt to deployed component — and shows exactly how the tool works, what it outputs, and where it fits in a development workflow.
The Workflow: Four Steps
Every PromptUI generation follows the same flow:
Describe
Write what you want in plain English
Generate
AI produces production-ready code
Preview
See the live result instantly
Export
Copy clean code into your project
The entire cycle — from typing your description to having usable code — typically takes under five minutes. That includes reviewing the output and making any refinements.
Example: A Pricing Card Section
Let's walk through a concrete example. Say you need a pricing section with three tiers for a SaaS landing page.
Step 1: The Prompt
A responsive pricing section with three cards: Starter at $9/mo, Pro at $29/mo (highlighted as most popular), and Enterprise at $99/mo. Each card has a title, price, 5 feature bullet points, and a CTA button. Dark theme with a subtle gradient background. Cards should have hover effects and the Pro card should be slightly elevated.
Step 2: What PromptUI Generates
From that single prompt, PromptUI generates:
- Semantic HTML — A
<section>with three<div>cards, proper heading hierarchy, and accessible button markup - Production CSS — Responsive grid layout, hover transitions, gradient background, card elevation, and the "most popular" highlight treatment
- Mobile-ready — Cards stack vertically on screens below 768px with maintained spacing and readability
The output is clean, commented where necessary, and follows modern CSS conventions (CSS Grid, custom properties, clamp() for responsive sizing). It's not a wireframe or mockup — it's code you can paste into a project and ship.
Output Formats
- HTML + CSS — Standalone markup with embedded or separate stylesheet
- React Component — JSX with CSS modules or styled-components
- Tailwind HTML — Utility-first markup for Tailwind CSS projects
Step 3: Preview and Refine
PromptUI renders a live preview of the generated component. You can see exactly how it looks before exporting. If something isn't right — the spacing is too tight, you want rounded corners instead of sharp ones, the CTA buttons need a different color — you describe the change in plain English and regenerate.
Each refinement counts as a generation. The system is designed for iteration: your initial prompt gets you 80-90% of the way there, and one or two follow-up prompts handle the details.
Step 4: Export
When you're satisfied, export the code. You get the raw HTML, CSS, and (if selected) React/Tailwind output. Copy it into your project, adjust the content, and deploy.
What Works Well
PromptUI is strongest in scenarios where you need:
- Common UI patterns — Pricing tables, hero sections, feature grids, testimonial carousels, navigation bars, footer layouts, card galleries
- Rapid prototyping — When you need a functional component fast and can refine later
- Design exploration — Trying multiple visual approaches to the same section without coding each one manually
- Consistent styling — Generating multiple components that share the same visual language
Best Practice
The more specific your prompt, the better the output. "A pricing section" gives a generic result. "A three-tier pricing section with dark theme, gradient cards, hover elevation, and a highlighted middle card" gives you something close to production-ready on the first generation.
Where It Fits in Your Workflow
PromptUI isn't a replacement for a designer or a frontend developer. It's an accelerator. Here's how teams typically use it:
- Solo developers use it to skip the blank-page problem. Generate a solid starting point, then customize.
- Design-to-dev handoff — Designers describe what they want, PromptUI generates the code, developers refine and integrate it.
- Freelancers use it to prototype client work faster. Show a working component in the first meeting instead of a mockup.
- Hackathons and MVPs — When speed matters more than pixel-perfection, generate your entire UI layer from prompts and focus your time on business logic.
Pricing
PromptUI uses a generation-based pricing model. Every prompt-to-output cycle counts as one generation.
| Tier | Price | Generations |
|---|---|---|
| Starter | $9 one-time | 10 AI generations |
| Pro | $29 one-time | 50 AI generations |
| Unlimited | $49/month | Unlimited generations |
Starter is enough for a single project — 10 generations covers 5-6 unique components with a refinement pass on each. Pro is the sweet spot for freelancers and teams working on multiple projects. Unlimited is for agencies or developers who use PromptUI as a daily workflow tool.
Technical Details
A few specifics for developers evaluating the tool:
- Output is standard code — No proprietary framework, no runtime dependency. The HTML, CSS, and React it generates work anywhere.
- No vendor lock-in — Once you export the code, it's yours. There's no PromptUI library you need to include in your project.
- Responsive by default — Every generation includes mobile-responsive breakpoints. You don't need to prompt for responsiveness; it's built in.
- Accessible markup — Generated HTML uses semantic elements, ARIA labels where appropriate, and keyboard-navigable interactive elements.
