Part 1. How Nano Banana Pro Helps With Mock Window UI Design
Nano Banana Pro is excellent at generating clean, realistic "fake screenshots" that look like real software in use. With the right Nano Banana Pro prompt for mock window UI design, you can quickly create desktop app windows, browser frames, and product dashboards that are polished enough for marketing pages, tutorials, or investor decks.
What Is a "Mock Window" UI?
A "mock window" UI is a fake desktop, app, or browser window that looks like a real screenshot but is fully generated by AI. Instead of designing every detail in Figma, you describe the scene and let Nano Banana Pro render:
- A desktop background with one or more app windows
- A browser frame with tabs, URL bar, and buttons
- A product interface or dashboard layout inside the window
These mock window UIs are perfect for SaaS hero images, step-by-step product tours, and polished pitch deck slides where you need believable product visuals fast.
Part 2. Nano-Banana Special Prompt Copy & Paste【Desktop Mock Window + Mobile】
Use the Nano Banana Pro image model with these ready-made prompts to generate high-fidelity desktop mock windows and mobile app UI mockups.
Just copy, paste, and tweak app names or colors as needed.
The key is to think in layers: first define the desktop background, then the window frame (browser or app), then the inner UI layout
(sidebars, nav bars, cards, charts), and finally the text you want to appear on buttons and headings.
To make this easier, here are some ready-to-use prompts you can copy directly into Nano Banana Pro:

FAQ About Nano Banana Pro UI Prompts
Q1: Can Nano Banana Pro really replace a UI designer?
No. Nano Banana Pro is a powerful assistant, not a replacement. It's great for ideation, quick mock window screenshots, and visual references, but a UI designer is still needed to create accessible, consistent, and production-ready interfaces. Think of Nano Banana Pro as a rapid sketcher that speeds up the early stages of design.
Q2: What's the difference between UI mockups and infographics in Nano Banana Pro?
UI mockups focus on screens, layouts, and interactive elements-things like navigation bars, buttons, cards, and forms that represent an app or website. Infographics focus on explaining information-timelines, flowcharts, comparisons, and statistics. In Nano Banana Pro, a UI mockup looks like a real product interface, while an infographic looks more like a visual report or slide, even if it borrows some UI-style components.
Q3: How detailed should my ai prompts for ui mockups be?
More detailed is usually better. Specify the platform (desktop, web, mobile), the window or frame (browser vs app), the main sections (hero, sidebar, cards, charts), and key text (headlines, button labels, menu items). You don't need to describe every pixel, but a strong ai prompt for ui mockups should clearly define layout, hierarchy, and style so the model doesn't have to guess.
Q4: Can I reuse one nano banana pro 4 screen mobile ui prompt for different apps?
Yes, and you should. A good nano banana pro 4 screen mobile ui prompt is essentially a reusable template for user journeys. You can keep the overall structure (e.g., Onboarding → Home → Detail → Analytics) and simply swap out the app name, features, and copy to fit a new product. This lets you build a consistent library of prompts while still generating unique flows for each app.
