The quality of your generated designs depends heavily on how well you write your prompts. A well-crafted prompt gives Moonchild a clear direction and produces designs that match your taste, while vague prompts lead to generic or misaligned results. Learning to write effective prompts is the most important skill for getting the most out of Moonchild.

Prompt Structure

The best prompts follow a simple structure:

1. Context (what you intend to design)
2. Description (things AI should consider; design priority)
3. Platform (your target platform: mobile, web)
4. Visual style (visual attributes you want to see in your generated design)
5. **Negative prompt (**things you don’t want to see in your generated designs)
6. UI components to include (list of specific components you want to see on a page/screen)

Note: It’s not necessary to include all of these structures in your prompt; these structures are just a guide to help you generate better designs. Feel free to be flexible with it.

Context

You should start with a sentence that defines what you’re designing. This helps Moonchild understand the project scope before generating the designs.

✅ Good context

• “Design a mobile dashboard UI for tracking expenses.”
• “Generate a minimal checkout screen for an e-commerce app.”
• “Design a sleek, informative home screen for a modern investment app.”

❌ Bad context

• “Create a login screen.”
• “Design a cool UI screen for a kid’s toy app.”

Description

Your description should be short and to the point, stating the most important aspects of the design.

Outline what really matters, such as user goals, interaction details, and priorities. Focus more on outcomes than outputs. This guides Moonchild in the right direction, producing better designs focused on functionality rather than just aesthetics.

✅ Good description

• "Traders should stay informed about current market trends and take quick action so they can respond to opportunities immediately.”
• "Build trust with first-time users by making the authentication process feel secure and straightforward so they feel confident sharing their information.”
• "Allow shoppers to discover products that match their values easily, so they feel good about their purchasing decisions.”

❌ Bad description

• “Make it nice.”
• “Professional and modern.”
• “Good design.”

Platform

Be specific about the device and the operating system (OS). This helps Moonchild follow platform guidelines and constraints, such as screen size, native components, layout, etc., available on that platform.

✅ Good platform description

• “Android Material 3 / Pixel 6 Pro (360 x 800)”
• *“*IOS 17 / iPhone 14 (390 x 844), using Human Interface Guidelines”
• “Web app in desktop resolution (1440x1024), responsive layout*”*

❌ Bad platform description

• “Web”
• “Mobile”
