How to use these prompts

  1. Open Nano Banana (Google Gemini) or ChatGPT.
  2. If the example starts from an image, upload your own sketch, model screenshot, photo or plan.
  3. Paste the prompt and adjust the materials, light and style words to your project.
  4. Refine in the same chat, e.g. "keep the composition, change to dusk lighting".

About this lesson

Streetscape is part of Vibe Coding: Build your own small design tools with AI, no coding background needed. Most of the 1 examples here run the same prompt through both Nano Banana and ChatGPT, so you can compare the two directly.

The Prompt

Prompt

"Build a professional Streetscape Design & Analysis web application using React, Tailwind CSS, and the Gemini API. CORE FUNCTIONALITY: Image Upload: Create a clean drag-and-drop area (with a fallback click-to-upload) for users to upload a high-resolution street photo. AI Site Analysis: Use gemini-3-flash-preview to analyze the photo. The AI should identify areas for urban improvement and return a JSON object containing: A general text analysis of the street's current performance. A list of specific suggestions (e.g., 'Add Bioswale', 'Install Bike Lane'). Bounding Box Annotations: Coordinates (0-1000) for where these improvements should be placed. Interactive Canvas Overlay: Implement an HTML Canvas that overlays the original photo. Draw the AI-provided annotations as white dashed bounding boxes with small black-background labels (e.g., 'Proposed Bike Lane'). AI Rendering (Image-to-Image): Use gemini-2.5-flash-image to generate a redesign. The prompt for the image generation must strictly: Maintain the exact same buildings, architecture, and street width as the original. Render specific proposal elements: colored bike lanes (green/terracotta), modern outdoor furniture, and low-impact planting/bioswales. Ensure consistent perspective and lighting. View Toggler: Provide a segmented control to switch between three modes: Original, Annotated (Canvas overlay), and Rendered (AI-generated image). DESIGN & UX: Aesthetic: Use a 'Clean Utility' or 'Technical Dashboard' style. Use the Inter font, a white/zinc color palette with Emerald-600 as the primary action color. Layout: A sticky header with the app name 'Streetscape AI', a large central image preview area, and a sidebar for 'Actions' and 'Site Analysis' results. Feedback: Include loading states (spinners) for the 'Analyzing' and 'Rendering' processes. Icons: Use lucide-react for all UI icons (Wand2, Search, Image, RefreshCw).

使用 React、Tailwind CSS 和 Gemini API,构建一个专业的街道景观设计与分析网页应用。 核心功能: 图片上传:创建一个干净的拖放区(并提供点击上传作为备选),供用户上传高分辨率街道照片。 AI 场地分析:使用 gemini-3-flash-preview 分析照片。AI 应识别可改进的城市区域,并返回一个 JSON 对象,包含: 对街道现状表现的总体文字分析。 具体建议清单(如“Add Bioswale 增加生态草沟”“Install Bike Lane 设置自行车道”)。 边界框标注:这些改进应放置位置的坐标(0–1000)。 交互式画布叠加:实现一个覆盖在原照片上的 HTML Canvas。把 AI 提供的标注画成白色虚线边界框,配黑色背景的小标签(如“Proposed Bike Lane 拟建自行车道”)。 AI 渲染(图生图):使用 gemini-2.5-flash-image 生成改造方案。图像生成的提示词必须严格做到: 保持与原图完全相同的建筑、建筑形态和街道宽度。 渲染具体的方案元素:彩色自行车道(绿色/陶土色)、现代户外家具,以及低影响种植/生态草沟。 确保透视和光线一致。 视图切换:提供一个分段控件,在三种模式之间切换:Original(原图)、Annotated(标注画布叠加)和 Rendered(AI 生成图)。 设计与体验: 美感:采用“Clean Utility(干净实用)”或“Technical Dashboard(技术仪表盘)”风格。使用 Inter 字体,白色/锌灰配色,Emerald-600 作为主要操作色。 版式:带应用名称“Streetscape AI”的固定顶栏,中央大幅图片预览区,以及用于“Actions(操作)”和“Site Analysis(场地分析)”结果的侧边栏。 反馈:为“Analyzing(分析中)”和“Rendering(渲染中)”过程加入加载状态(加载动画)。 图标:所有 UI 图标使用 lucide-react(Wand2、Search、Image、RefreshCw)。

Questions

Streetscape

What do I need to do streetscape with AI?

Only Nano Banana and ChatGPT. Upload your source image and paste a prompt from this page. There are 1 worked examples here to follow.

Is Nano Banana or ChatGPT better for streetscape?

Most examples on this page run the same prompt through both tools and show the results side by side. Nano Banana usually keeps the composition and geometry of the input closer, while ChatGPT pushes the style further.

Can I use these prompts for client work?

Yes. The prompts can be used in your own design projects, competitions and portfolio.
