We've all created apps using AI tools like Cursor, Lovable etc. A common prompt that all of us has at least once asked them is “Make it beautiful”.
"Make it Beautiful" - Expectation vs Reality
You’d expect a mind blowing UI with slick animations to create itself in front of your eyes. But that doesn’t happen. You get purple gradients buttons over dark background, bordered cards and content with Sans Serif Fonts. It’s fine but it’s also how every AI created website looks.
But how to fix this? Are LLMs incapable of generating good looking UIs? The answer is, not really.
Design Systems are Key
Every beautiful website you see is based on a design system. Designers spend weeks curating a color palette, choosing the right fonts, figuring how buttons, input fields, cards and components will feel, detailing their interactions and making sure the website has a tight cohesive look!
Yes, AI tools are not great at coming up with design systems on the fly. But, they are great at copying them into your apps.
So the bottleneck is not AI, but the missing design system.
The Core Elements of a Design System
A design system is typically broken down into a few key parts:
| Piece of the System | What it means (in simple terms) | How it helps AI tools |
|---|---|---|
| Colors | A fixed set of brand colors for buttons, text, and backgrounds. | Doesn’t guess random shades — always uses your exact brand colors. |
| Typography (Text Rules) | The fonts, sizes, and spacing used for headings, paragraphs, and links. | Knows which font size or weight to use for each type of text, keeping things consistent. |
| Style & Layout | The “rules of the road” for spacing, rounded corners, shadows, and grids. | Applies the same spacing and styles everywhere, making the whole app feel cohesive. |
| Component Examples | Ready-made pieces like buttons, input fields, and cards showing how it all comes together. | Uses proven references instead of inventing layouts, so output looks polished. |
When you combine these elements into a single prompt, you're not asking the LLM to be a designer anymore. You're asking it to be a very efficient developer that's an expert in your design system.
The vague "make it beautiful" prompt becomes a highly specific instruction:
"Build a landing page using the provided design system. Use the
h1-herostyle for the main title,btn-primaryfor the call-to-action, and arrange the feature cards as shown in the component examples, applying the defined shadows and corner radii."
This is why it works so well. You're replacing ambiguity with precision. The LLM excels at this, translating your detailed design DNA into a pixel-perfect UI that is not just "fine," but truly well-designed.
