Your Prompt
prompt.txt
Generate AI prompts to create realistic UI mockups for portfolio case studies and presentations.

**Project Context:**
- Project type: SaaS analytics dashboard
- Industry: Fintech — transaction monitoring and reporting
- Device: Desktop web application (MacBook Pro frame)
- Design style: Modern minimal with data-dense layouts, subtle shadows, clean typography
- Key screens needed: Dashboard, transaction detail, settings, onboarding wizard, mobile responsive

**Generate Prompts for Each Screen:**

**1. Hero/Dashboard Screen:**
```
Realistic UI screenshot of a SaaS analytics dashboard Desktop web application (MacBook Pro frame) application, Modern minimal with data-dense layouts, subtle shadows, clean typography design, showing a dashboard with data cards, charts, and navigation sidebar, Navy (#1E293B), electric blue (#3B82F6), emerald (#10B981), white background color scheme, high fidelity mockup, professional UI design, sharp and crisp, realistic device frame, 4K quality
```

**2. Detail/Content Screen:**
```
[Prompt for an inner page showing detailed content, forms, or data tables]
```

**3. Mobile Responsive View:**
```
[Prompt for mobile version of the same app, showing responsive adaptation]
```

**4. Dark Mode Variant:**
```
[Prompt for the same screen in dark mode with proper contrast and accessibility]
```

**5. Empty/Onboarding State:**
```
[Prompt for the first-time user experience with onboarding guidance]
```

**6. Notification center with alert categories and action items:**
```
[Custom screen prompt]
```

**Device Framing Options:**
Generate each screen in these contexts:
- **Clean screenshot** — no device frame, just the UI
- **Device mockup** — inside a realistic Desktop web application (MacBook Pro frame) frame
- **Lifestyle context** — device on a desk, in hand, in meeting context
- **Multi-device** — responsive showcase across laptop, tablet, mobile

**Portfolio Presentation Layouts:**
Design prompts for case study presentations:

**Layout A — Hero Shot:**
```
[Single large mockup with dramatic angle and shadow]
```

**Layout B — Feature Grid:**
```
[Multiple screens arranged in a grid showing feature variety]
```

**Layout C — Flow Sequence:**
```
[3-5 screens showing a user journey from start to completion]
```

**Consistency Rules:**
- Use the SAME Navy (#1E293B), electric blue (#3B82F6), emerald (#10B981), white background across all screens
- Maintain consistent typography sizing and spacing
- Navigation elements should match across all views
- Data should look realistic (not lorem ipsum or obvious fakes)
- All charts should use the same chart library visual style (e.g., Recharts or Chart.js look)

**Post-Processing Guide:**
1. Generate base UI screenshots
2. Enhance in Figma: add real text, fix alignment, ensure pixel-perfection
3. Apply device frames using Rotato or Figma with device frame plugin
4. Add subtle shadows and background for presentation context
5. Export at 2x resolution for retina displays

**What to Avoid:**
- Blurry or low-resolution UI elements
- Unrealistic data (round numbers everywhere, perfect metrics)
- Text that's too small to read in the mockup
- Inconsistent UI patterns between screens
- Overly generic "lorem ipsum" looking content

What this prompt does

This prompt generates AI image prompts for realistic UI mockups and app screenshots, aimed at portfolio case studies when the real product isn't ready to show. You describe the [project_type], [industry], [device_type], [design_style], and [screens_needed], and it writes prompts for each key screen plus device-framing options, presentation layouts, consistency rules, and a post-processing guide.

The structure is built for believable, cohesive mockups. It generates prompts for a hero/dashboard screen, a detail screen, a mobile responsive view, a dark-mode variant, and an onboarding/empty state — all sharing the same [color_palette] and [design_style] so the set reads as one product. Because you set [device_type], the prompts request the right frame (a MacBook Pro, a phone) and offer clean-screenshot, device-mockup, and lifestyle-context variants. The consistency rules insist on realistic data instead of obvious lorem ipsum, and [consistency_note] lets you lock details like a shared chart-library look.

When to use it

  • When you need portfolio mockups for a project whose real product isn't shippable yet.
  • To produce a cohesive set of screens (dashboard, detail, mobile, dark mode) for a case study.
  • When you want device-framed and lifestyle-context versions of the same UI.
  • To build a flow-sequence layout showing a user journey across several screens.
  • When you need the mockups to look like a real product, not a generic template.

Example output

You get AI prompts for each screen — hero/dashboard, detail/content, mobile responsive, dark-mode variant, and onboarding/empty state — each using your [color_palette] and [design_style]. Then device-framing options (clean screenshot, device mockup, lifestyle context, multi-device), portfolio presentation layouts (hero shot, feature grid, flow sequence), consistency rules for typography, navigation, and realistic data, and a post-processing guide for refining in Figma, applying device frames, and exporting at 2x for retina.

Pro tips

  • Use a single named [color_palette] with hex codes across every screen prompt — consistency is what makes the set look like one product rather than five.
  • Keep the data realistic: the consistency rules warn against round numbers and lorem ipsum, so describe believable content in [screens_needed].
  • Match [device_type] to your target frame (MacBook Pro, specific phone) so the mockups sit in the right device context.
  • Treat AI output as a base, then refine in Figma — fix alignment, add real text, and ensure pixel-perfection before it goes in a portfolio.
  • Use [consistency_note] to lock cross-screen details, like making all charts share one chart-library visual style.
  • Generate the dark-mode variant from the same screen so contrast and layout stay faithful rather than reinvented.

Frequently Asked Questions

Are these real screenshots or AI-generated images?
They are AI-generated mockups, not screenshots of working software. The prompt is meant for portfolio case studies when the real product isn't shippable yet, so refine the output in Figma to make it convincing.
How do I keep all the screens looking consistent?
Use a single named `[color_palette]` with hex codes and a consistent `[design_style]` across every screen prompt. The consistency rules also enforce matching typography, navigation, and realistic data so the set reads as one product.
Can it produce a dark-mode version?
Yes. One of the standard screen prompts generates a dark-mode variant with proper contrast and accessibility. Generate it from the same screen so the layout stays faithful to the light version rather than being reinvented.
Does it include device frames?
Yes. It offers framing options for each screen: a clean frameless screenshot, a realistic device mockup matching your `[device_type]`, a lifestyle context shot, and a multi-device responsive showcase.
Will the mockups have realistic data?
They will if you guide them. The consistency rules explicitly warn against lorem ipsum and round-number placeholders, so describe believable content in `[screens_needed]` and refine the data in post-processing.
