AI-Generated UI Style Guides from Brand Guidelines Videos

TL;DR: Replay leverages AI, specifically Gemini, to analyze brand guideline videos and generate comprehensive, working UI style guides, saving developers countless hours.

From Brand Video to Living Style Guide: AI-Powered UI Generation#

Creating a consistent and scalable UI is paramount for any successful product. Brand guidelines, often presented in video format, are the single source of truth, but translating those abstract guidelines into concrete, working code is a time-consuming and error-prone process. What if AI could bridge that gap? What if you could point an AI to your brand guideline video and have it automatically generate a functional UI style guide? That's the power of Replay.

Traditional methods rely on manual interpretation and implementation, leading to inconsistencies and delays. Screenshot-to-code tools offer a partial solution, but they lack the understanding of intent behind the visual elements. They capture the what, but not the why. Replay, on the other hand, analyzes video, using "Behavior-Driven Reconstruction" to understand user behavior and intent, creating a more robust and accurate representation of your brand's UI.

The Problem: Manual Style Guide Implementation#

Consider the typical workflow. A designer creates a beautiful brand guideline video, showcasing typography, color palettes, component usage, and interaction patterns. Then, a developer must painstakingly translate that video into a living style guide – a collection of reusable components and CSS styles that define the look and feel of the application. This process involves:

1. •Watching the video, repeatedly pausing and rewinding.
2. •Manually extracting color codes, font sizes, and spacing values.
3. •Writing CSS classes and component definitions.
4. •Testing and refining the implementation to match the video.

This is tedious, time-consuming, and prone to human error. Small discrepancies can accumulate, leading to inconsistencies across the UI and a diluted brand experience.

Replay: The Video-to-Code Revolution#

Replay offers a radically different approach. By analyzing the brand guideline video directly, Replay can automatically generate a working UI style guide, complete with:

• •Reusable React components.
• •CSS modules with consistent naming conventions.
• •A documentation site showcasing the components and styles.

This process is significantly faster, more accurate, and less prone to human error than manual implementation. Replay understands the flow of the brand guidelines, not just static snapshots.

How Replay Works: Behavior-Driven Reconstruction#

Replay uses a sophisticated AI engine, powered by Gemini, to analyze video and understand user behavior. This "Behavior-Driven Reconstruction" approach allows Replay to:

1. •Identify UI elements: Replay can recognize buttons, text fields, images, and other common UI elements.
2. •Analyze interactions: Replay understands how users interact with these elements – clicks, hovers, form submissions, etc.
3. •Extract styles: Replay automatically extracts color palettes, typography, spacing, and other visual styles.
4. •Generate code: Replay generates clean, well-structured code that implements the identified UI elements and styles.

This process is not just about converting pixels to code. It's about understanding the intent behind the video and translating that intent into a functional UI.

Comparison with Existing Tools#

As you can see, Replay offers a unique combination of features that address the limitations of existing tools.

Step-by-Step Guide: Generating a UI Style Guide with Replay#

Let's walk through a practical example of how to generate a UI style guide from a brand guideline video using Replay.

Step 1: Upload Your Brand Guideline Video

The first step is to upload your brand guideline video to the Replay platform. Replay supports various video formats and resolutions.

💡 Pro Tip: Ensure your video is clear and well-lit for optimal results. The clearer the video, the more accurate the AI analysis will be.

Step 2: Configure Replay Settings

Next, configure Replay settings to customize the output. This includes:

• •Target Framework: Select the target framework (e.g., React, Vue, Angular).
• •Component Library: Choose a base component library (e.g., Material UI, Ant Design). This provides a foundation for the generated components.
• •Naming Conventions: Define naming conventions for CSS classes and component names.

json
{
  "framework": "react",
  "componentLibrary": "material-ui",
  "namingConventions": {
    "cssClass": "kebab-case",
    "componentName": "PascalCase"
  }
}

Step 3: Run Replay and Review the Output

Click the "Generate" button to start the AI analysis. Replay will analyze the video, identify UI elements, extract styles, and generate code. This process may take a few minutes, depending on the length of the video.

Once the process is complete, review the generated code and make any necessary adjustments. Replay provides a visual editor that allows you to fine-tune the components and styles.

Step 4: Integrate with Your Project

Finally, integrate the generated UI style guide into your project. Replay provides several options for integration:

• •Download: Download the generated code as a zip file.
• •GitHub Integration: Push the code to a GitHub repository.
• •NPM Package: Publish the style guide as an NPM package.
• •Supabase Integration: Seamlessly integrate with Supabase for data management and authentication.

📝 Note: Replay also offers style injection, allowing you to apply the generated styles directly to your existing application without modifying your codebase.

Example Code: Generated Button Component#

Here's an example of a React button component generated by Replay:

typescript
// Button.tsx
import React from 'react';
import styles from './Button.module.css';

interface ButtonProps {
  children: React.ReactNode;
  onClick: () => void;
}

const Button: React.FC<ButtonProps> = ({ children, onClick }) => {
  return (
    <button className={styles.button} onClick={onClick}>
      {children}
    </button>
  );
};

export default Button;

css
/* Button.module.css */
.button {
  background-color: #007bff;
  color: #fff;
  padding: 10px 20px;
  border: none;
  border-radius: 5px;
  cursor: pointer;
  font-size: 16px;
}

.button:hover {
  background-color: #0056b3;
}

This code is clean, well-structured, and follows best practices. The CSS is modular, preventing naming conflicts and ensuring maintainability.

⚠️ Warning: While Replay strives for accuracy, it's crucial to review the generated code and make any necessary adjustments to ensure it meets your specific requirements.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features and usage. Paid plans are available for more advanced features and higher usage limits.

How is Replay different from v0.dev?#

While both Replay and v0.dev aim to accelerate UI development, they differ significantly in their approach. v0.dev primarily relies on text prompts and generative AI to create UI components. Replay, on the other hand, analyzes video to understand user behavior and intent, resulting in more accurate and context-aware UI generation. Replay focuses on recreating existing designs from video, while v0.dev focuses on generating new designs from text. Replay's behavior-driven reconstruction provides a more faithful representation of your brand's UI.

What video formats are supported?#

Replay supports a wide range of video formats, including MP4, MOV, AVI, and WMV.

Can I customize the generated code?#

Yes, Replay provides a visual editor that allows you to fine-tune the generated components and styles. You can also download the code and modify it directly.

Does Replay support other frameworks besides React?#

Yes, Replay supports Vue and Angular, with plans to support more frameworks in the future.
