Replay AI for Generating Design Documentation With Figma & Video Input

TL;DR: Replay AI revolutionizes design documentation by generating interactive Figma prototypes and production-ready code directly from user behavior captured in video recordings, offering a more accurate and efficient alternative to traditional methods.

From Video to Figma: Replay AI Redefines Design Documentation#

Creating comprehensive design documentation is often a tedious and time-consuming process. Traditional methods, relying on static screenshots and manual annotation, often fail to capture the dynamic nature of user interactions and product flows. What if you could automatically generate interactive Figma prototypes and production-ready code directly from video recordings of user behavior? That's the power of Replay.

Replay leverages the power of Gemini to analyze video, understand user intent, and reconstruct working UI components, offering a streamlined approach to design documentation and development. It's about more than just replicating what's on the screen; it's about understanding why users interact with the UI in specific ways.

The Problem with Traditional Design Documentation#

Traditional design documentation methods are plagued with several issues:

• •Static and Incomplete: Screenshots and static mockups fail to capture the dynamic nature of user interactions.
• •Time-Consuming: Manually annotating screenshots and creating flow diagrams is a labor-intensive process.
• •Prone to Errors: Human error during manual documentation can lead to inaccuracies and inconsistencies.
• •Difficult to Maintain: Updating documentation to reflect changes in the UI requires significant effort.

Introducing Behavior-Driven Reconstruction with Replay#

Replay addresses these challenges by introducing a novel approach: behavior-driven reconstruction. Instead of relying on static images, Replay analyzes video recordings of user interactions to understand the underlying user intent and reconstruct the UI accordingly. This approach offers several advantages:

• •Dynamic and Interactive: Replay generates interactive Figma prototypes that accurately reflect user behavior.
• •Automated and Efficient: Replay automates the documentation process, saving time and reducing manual effort.
• •Accurate and Consistent: Replay minimizes human error by automatically extracting information from video recordings.
• •Easy to Maintain: Replay can easily regenerate documentation whenever the UI or user behavior changes.

Replay in Action: Generating Design Documentation#

Here's how Replay simplifies the design documentation process:

1. •Record User Interactions: Capture video recordings of users interacting with your application or website.
2. •Upload to Replay: Upload the video recordings to the Replay platform.
3. •Replay Analyzes and Reconstructs: Replay analyzes the video, identifies UI elements, and understands user interactions.
4. •Generate Figma Prototype and Code: Replay automatically generates an interactive Figma prototype and production-ready code based on the analysis.

Key Features of Replay for Design Documentation#

• •Multi-Page Generation: Replay can generate prototypes and code for multi-page applications, capturing complex user flows.
• •Supabase Integration: Seamlessly integrate with Supabase to generate documentation for data-driven applications.
• •Style Injection: Customize the look and feel of the generated prototypes and code by injecting custom styles.
• •Product Flow Maps: Visualize user flows with automatically generated product flow maps.

Comparison: Replay vs. Traditional Methods & Screenshot-to-Code Tools#

📝 Note: Screenshot-to-code tools are helpful for simple UI elements, but they lack the understanding of user behavior that Replay provides.

Tutorial: Generating a Simple Form with Replay#

Let's walk through a simple example of using Replay to generate a form:

Step 1: Record the Interaction#

Record a video of a user filling out a simple form. This could be a login form, a contact form, or any other form in your application.

Step 2: Upload to Replay#

Upload the video to Replay.

Step 3: Replay Analyzes the Video#

Replay will analyze the video and identify the form elements, input fields, and submit button.

Step 4: Generate Code#

Replay will generate the corresponding React code for the form:

typescript
// Example React Form Code Generated by Replay
import React, { useState } from 'react';

const LoginForm = () => {
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');

  const handleSubmit = (e) => {
    e.preventDefault();
    console.log('Email:', email, 'Password:', password);
    // Add your authentication logic here
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="email">Email:</label>
        <input
          type="email"
          id="email"
          value={email}
          onChange={(e) => setEmail(e.target.value)}
          required
        />
      </div>
      <div>
        <label htmlFor="password">Password:</label>
        <input
          type="password"
          id="password"
          value={password}
          onChange={(e) => setPassword(e.target.value)}
          required
        />
      </div>
      <button type="submit">Login</button>
    </form>
  );
};

export default LoginForm;

Step 5: Figma Prototype#

Replay also generates an interactive Figma prototype of the form, allowing you to further refine the design and user experience.

💡 Pro Tip: Use high-quality video recordings for optimal results. Ensure that the UI elements are clearly visible and that the user interactions are smooth.

Advanced Use Cases#

Replay isn't just for simple forms. It can handle complex user flows and data-driven applications. Here are some advanced use cases:

• •E-commerce Checkout Flows: Generate documentation for complex checkout flows, including address validation, payment processing, and order confirmation.
• •Dashboard UIs: Reconstruct interactive dashboards with charts, graphs, and data tables.
• •Mobile App Prototypes: Create prototypes for mobile apps by recording user interactions on a mobile device.

⚠️ Warning: While Replay excels at generating code and prototypes, it's important to review the generated output and make any necessary adjustments to ensure accuracy and consistency.

Integrating with Supabase#

Replay's Supabase integration allows you to generate documentation for applications that rely on real-time data. By connecting Replay to your Supabase project, you can automatically generate prototypes and code that reflect the current state of your data.

typescript
// Example of fetching data from Supabase (using Replay-generated code as a starting point)
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = 'YOUR_SUPABASE_URL';
const supabaseKey = 'YOUR_SUPABASE_ANON_KEY';
const supabase = createClient(supabaseUrl, supabaseKey);

const fetchData = async () => {
  const { data, error } = await supabase
    .from('products')
    .select('*');

  if (error) {
    console.error('Error fetching data:', error);
    return [];
  }

  return data;
};

This allows you to automatically generate UI components that display and interact with the data stored in your Supabase database.

Frequently Asked Questions#
