Better Designs.Fewer AI Tokens.

Turn vague design taste into a precise prompt for stronger AI mockups.

How to think about prompts

Describe the design before you generate.

Give the model a few clear design choices so it has less visual taste to guess.

Name the vibe

Choose the feeling before the model invents one.

Vague

Modern dashboard

Descriptive

Quiet, focused, executive dashboard

Add visual rules

Give clear direction for color, type, spacing, and components.

Vague

Use nice colors

Descriptive

Ivory canvas, ink panels, gold actions

Say what to avoid

Tell the model what not to do so the result feels less generic.

Vague

Make it polished

Descriptive

Avoid generic glass and oversized hero cards

Before / After

Stop asking AI tools to guess the design.

A vague request makes the model invent the style. A clearer prompt gives it the taste, palette, spacing, and boundaries up front.

Before

A vague prompt

vague
Build me a slick dashboard
Make it modern and premium
Use good spacing and charts
Give me a nice starting point

The model has to guess the aesthetic, palette, layout, and what “premium” means.

After

A clearer design prompt

specific
1

Design a compact B2B analytics dashboard with a calm executive feel and strong scan hierarchy.

2

Use ink panels on a warm off-white canvas, gold primary actions, and cyan status accents.

3

Favor tight spacing, readable data labels, clear hover states, and restrained chart styling.

4

Avoid generic glassmorphism, oversized marketing sections, and decorative filler.
