Replay AI: The Only Way to Convert User Flow Videos to React Components in 2026

TL;DR: Replay AI is the only platform in 2026 capable of truly converting user flow videos into functional React components by understanding user behavior, not just visual elements.

The Screenshot-to-Code Era is Over: Welcome to Behavior-Driven Reconstruction#

In 2026, the landscape of UI development has fundamentally shifted. The days of painstakingly converting static screenshots into code are relics of the past. The problem? Screenshots only capture a single moment in time, missing the crucial context of user intent and dynamic interactions.

That's where Replay AI comes in. We're not just another screenshot-to-code tool. We've pioneered Behavior-Driven Reconstruction, a revolutionary approach that analyzes video recordings of user flows to generate fully functional React components. Replay understands what users are trying to do, not just what they see.

Why Video is the Future of Code Generation#

The fundamental flaw with screenshot-based approaches is their inability to capture dynamic behavior. A button might look clickable in a screenshot, but the code needs to reflect the action of clicking it. Replay solves this by analyzing video, the source of truth for user interactions.

Here's a breakdown of the key advantages:

• •Contextual Understanding: Replay AI analyzes the sequence of actions within the video to infer user intent. This goes far beyond simple OCR or image recognition.
• •Dynamic Element Handling: Replay can identify and generate code for dynamic elements that change based on user input or application state.
• •Complete Flow Reconstruction: Replay can reconstruct entire user flows spanning multiple pages, capturing the full user journey.

Replay AI: Deep Dive into the Architecture#

Replay's engine is built on a multi-layered architecture leveraging cutting-edge AI models, including a custom fine-tuned version of Gemini. Here's a simplified overview:

1. •Video Processing: The input video is processed frame-by-frame, extracting visual and behavioral data.
2. •Behavioral Analysis: This is where the magic happens. Replay's AI models analyze user interactions (clicks, scrolls, form inputs) to understand the underlying intent.
3. •Component Reconstruction: Based on the behavioral analysis, Replay generates React components with the necessary logic and styling.
4. •Code Generation: The reconstructed components are then translated into clean, production-ready React code.

Let's look at a practical example. Imagine a user recording themselves filling out a form:

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

const UserForm = () => {
  const [name, setName] = useState('');
  const [email, setEmail] = useState('');

  const handleSubmit = (e: React.FormEvent) => {
    e.preventDefault();
    console.log(`Submitted: Name - ${name}, Email - ${email}`);
    // Add your submission logic here
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="name">Name:</label>
        <input
          type="text"
          id="name"
          value={name}
          onChange={(e) => setName(e.target.value)}
        />
      </div>
      <div>
        <label htmlFor="email">Email:</label>
        <input
          type="email"
          id="email"
          value={email}
          onChange={(e) => setEmail(e.target.value)}
        />
      </div>
      <button type="submit">Submit</button>
    </form>
  );
};

export default UserForm;

This code isn't just a static representation of the form. It includes the necessary state management and event handling to capture user input and submit the form data. Replay AI understands the purpose of the form, not just its appearance.

Key Features that Set Replay Apart#

Replay isn't just about converting video to code; it's about building complete, functional UIs. Here are some of the key features that make Replay the leading solution in 2026:

• •Multi-Page Generation: Reconstruct entire user flows, even those spanning multiple pages.
• •Supabase Integration: Seamlessly integrate with your Supabase backend for data persistence.
• •Style Injection: Automatically apply consistent styling based on your existing design system.
• •Product Flow Maps: Visualize the reconstructed user flow for easy understanding and modification.

Replay in Action: A Real-World Scenario#

Let's say you're building an e-commerce application. You want to recreate a specific checkout flow that you observed during user testing. Instead of manually coding the entire flow from scratch, you can simply record a video of the user interaction and upload it to Replay.

Replay will then:

1. •Analyze the video, identifying each step in the checkout process (adding items to cart, entering shipping information, payment details, etc.).
2. •Generate React components for each screen in the flow, including the necessary state management and event handling.
3. •Connect these components together to create a complete, functional checkout flow.
4. •Offer a flow map to visualize the process for easy debugging or modification.

This significantly reduces development time and ensures that the reconstructed flow accurately reflects the user's intended behavior.

Comparing Replay to Legacy Approaches#

Here's a comparison of Replay AI against traditional screenshot-to-code tools:

💡 Pro Tip: Use Replay in conjunction with user testing to quickly iterate on your UI designs based on real user behavior.

Step-by-Step Guide to Using Replay AI#

Here's a simple tutorial to get you started with Replay:

Step 1: Record Your User Flow#

Use any screen recording tool to capture the user flow you want to reconstruct. Ensure the video is clear and captures all relevant user interactions.

Step 2: Upload to Replay#

Upload the video to the Replay AI platform.

Step 3: Review and Customize#

Replay will automatically analyze the video and generate React components. Review the generated code and make any necessary customizations.

Step 4: Integrate into Your Project#

Copy and paste the generated code into your React project. Integrate the components with your existing codebase and backend services.

javascript
// Example: Integrating Replay-generated component
import CheckoutForm from './ReplayGenerated/CheckoutForm';

function App() {
  return (
    <div className="App">
      <CheckoutForm />
    </div>
  );
}

export default App;

📝 Note: Replay supports various customization options, allowing you to fine-tune the generated code to match your specific requirements.

Advanced Features: Beyond Basic Code Generation#

Replay AI offers a range of advanced features that go beyond basic code generation:

• •Component Mapping: Map Replay-generated components to your existing component library.
• •State Management Integration: Automatically integrate with your preferred state management library (Redux, Zustand, etc.).
• •Accessibility Auditing: Ensure that the generated code meets accessibility standards.

⚠️ Warning: While Replay strives to generate high-quality code, it's always important to review and test the generated code thoroughly before deploying it to production.

Frequently Asked Questions#

Is Replay AI free to use?#

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

How is Replay AI different from v0.dev?#

While v0.dev generates code based on text prompts, Replay analyzes video of actual user behavior, resulting in more accurate and context-aware code. Replay focuses on reconstructing existing flows, while v0.dev is more geared towards generating new UI from scratch.

What kind of video formats does Replay support?#

Replay supports most common video formats, including MP4, MOV, and AVI.

What if the generated code needs adjustments?#

The generated code is fully editable. Replay provides a solid foundation, allowing you to easily customize and extend the generated components.
