Replay AI: The Complete Guide to Converting Wireframes in Video to React Code

TL;DR: Replay AI leverages video analysis to generate functional React code from wireframe recordings, offering a more intuitive and accurate approach than traditional screenshot-based methods.

Static wireframes are dead. Or, at least, they should be. In today's fast-paced development environment, relying on static images to translate design intent into functional code is like trying to navigate with a map from the 1800s. It's outdated, inefficient, and misses crucial context. The real gold lies in understanding user behavior and intent, which is precisely what video captures.

This is where Replay AI comes in. We're not just another screenshot-to-code tool. We use video as the source of truth, employing "Behavior-Driven Reconstruction" to generate working UI directly from screen recordings of your wireframes. Think of it as turning your design walkthroughs into deployable React components.

Why Video-to-Code is the Future#

The problem with screenshot-to-code tools is fundamental: they only see what's visible. They don't understand the why behind the design. They can't decipher user flows, dynamic interactions, or the intended purpose of each element. This leads to brittle code that requires extensive manual tweaking and debugging.

Video, on the other hand, captures the entire user journey. It reveals the sequence of actions, the transitions between states, and the subtle nuances of user interaction. Replay AI analyzes this rich data to reconstruct not just the visual appearance of the UI, but also its underlying behavior.

Consider this scenario: you've created a wireframe of a multi-step form. A screenshot-to-code tool might generate the individual form elements, but it won't understand the flow between steps, the validation logic, or the conditional display of elements based on user input. Replay AI, by analyzing a video of you interacting with the wireframe, does understand all of this.

Replay AI: A Technical Deep Dive#

Replay AI uses a multi-stage process to convert video wireframes into React code:

1. •

   Video Analysis: The video is processed to identify UI elements, user interactions (clicks, scrolls, keyboard input), and state transitions. We leverage Gemini's advanced video understanding capabilities for this.

2. •

   Behavior Reconstruction: Based on the identified interactions, Replay AI reconstructs the intended behavior of the UI. This includes defining event handlers, state management logic, and data flow.

3. •

   Code Generation: Finally, Replay AI generates clean, well-structured React code that implements the reconstructed behavior. This code is designed to be easily maintainable and extensible.

Key Features#

Replay AI offers a range of features designed to streamline the development process:

• •Multi-page Generation: Generate code for entire applications, not just individual screens. Replay AI understands how different pages connect and interact.
• •Supabase Integration: Seamlessly integrate your generated code with Supabase for backend functionality, including authentication, data storage, and real-time updates.
• •Style Injection: Customize the look and feel of your UI by injecting custom CSS or using pre-built style libraries like Tailwind CSS or Material UI.
• •Product Flow Maps: Visualize the user flow through your application with automatically generated flow maps. This helps you identify potential bottlenecks and improve the user experience.

Replay AI vs. The Competition#

Let's be honest, there are other tools out there that claim to convert designs into code. But they all fall short in one crucial area: understanding behavior.

💡 Pro Tip: Don't be fooled by tools that promise "AI-powered" code generation based solely on screenshots. Look for tools that actively analyze user behavior and interaction patterns.

Getting Started with Replay AI: A Step-by-Step Guide#

Here's how to turn your video wireframes into React code with Replay AI:

Step 1: Record Your Wireframe Walkthrough#

Use any screen recording tool (QuickTime, Loom, etc.) to record yourself interacting with your wireframe. Be sure to demonstrate all the key user flows and interactions. Speak clearly and explain your design decisions as you go.

📝 Note: The clearer and more detailed your video, the better the generated code will be.

Step 2: Upload Your Video to Replay AI#

Simply drag and drop your video file into the Replay AI interface. Our system will automatically process the video and extract the relevant information.

Step 3: Review and Refine the Generated Code#

Replay AI will generate a preview of the React code. Review the code and make any necessary adjustments. You can customize the styling, add additional functionality, or refactor the code to your liking.

Step 4: Integrate with Your Project#

Download the generated code and integrate it into your existing React project. You can use Replay AI's Supabase integration to connect your UI to a backend database.

Example: Generating a Simple Counter Component#

Let's say you have a wireframe of a simple counter component with increment and decrement buttons. Here's how Replay AI might generate the React code:

typescript
// Generated by Replay AI
import React, { useState } from 'react';

const Counter = () => {
  const [count, setCount] = useState(0);

  const increment = () => {
    setCount(count + 1);
  };

  const decrement = () => {
    setCount(count - 1);
  };

  return (
    <div>
      <button onClick={decrement}>-</button>
      <span>{count}</span>
      <button onClick={increment}>+</button>
    </div>
  );
};

export default Counter;

This is a simplified example, of course. But it demonstrates the basic principle of how Replay AI can automatically generate functional React code from video wireframes.

⚠️ Warning: While Replay AI can generate a significant amount of code automatically, it's not a magic bullet. You'll still need to review and refine the generated code to ensure it meets your specific requirements.

Beyond Basic Wireframes: Replay AI's Potential#

Replay AI is not just for simple wireframes. It can handle complex UIs, dynamic interactions, and multi-page applications. Imagine using Replay AI to:

• •Generate a complete e-commerce website from a video walkthrough of your design.
• •Create a fully functional mobile app from a screen recording of your prototype.
• •Automatically generate unit tests based on the user interactions captured in your video.

The possibilities are endless. By leveraging the power of video analysis, Replay AI is transforming the way we build software.

Frequently Asked Questions#

Is Replay AI free to use?#

Replay AI offers a free tier with limited functionality. Paid plans are available for users who need access to advanced features and higher usage limits. Check our pricing page for the latest details.

How is Replay AI different from v0.dev?#

While both tools aim to accelerate UI development, they differ significantly in their approach. v0.dev relies on text prompts to generate code, while Replay AI uses video analysis. Replay AI is better suited for capturing complex user flows and dynamic interactions that are difficult to describe in text.

What types of videos work best with Replay AI?#

The best videos are clear, well-lit, and demonstrate all the key user flows and interactions. Speak clearly and explain your design decisions as you go.

What if Replay AI generates incorrect code?#

Replay AI is constantly improving, but it's not perfect. If you encounter incorrect code, you can manually edit the generated code or provide feedback to our team to help us improve the accuracy of our AI models.

What frameworks and libraries does Replay AI support?#

Currently, Replay AI primarily supports React. We are actively working on expanding support for other frameworks and libraries in the future.
