TL;DR: Replay AI revolutionizes UI migration by directly converting video recordings of user interactions into fully functional code, significantly accelerating development cycles and improving accuracy compared to screenshot-based methods.

Replay AI: The Ultimate Guide to Rapid UI Migration from Video in 2026#

Migrating existing user interfaces (UIs) to new frameworks or platforms is traditionally a time-consuming and error-prone process. Manually recreating interfaces based on static screenshots often misses crucial interactive elements and user flow nuances, leading to significant rework and inconsistent user experiences. But what if you could simply record your UI in action and have AI reconstruct it into working code? That's the promise of Replay.

Replay AI leverages advanced video analysis and generative AI to build working UIs directly from video recordings, a process we call "Behavior-Driven Reconstruction." This approach not only captures the visual elements but also understands user intent and behavior, resulting in more accurate and functional code generation.

The Problem with Screenshot-to-Code#

Traditional screenshot-to-code tools offer a limited solution. They can generate code based on visual elements, but they fail to capture the dynamic aspects of a UI. This often results in static representations that lack interactivity and require extensive manual adjustments. Consider the following comparison:

The table clearly shows the superiority of Replay AI in capturing and understanding user behavior, leading to more accurate and functional code generation.

Replay AI: Behavior-Driven Reconstruction Explained#

Replay AI operates on the principle of Behavior-Driven Reconstruction. Instead of just analyzing static images, it analyzes the entire video recording of user interactions with the UI. This allows Replay AI to understand:

  • User flow: How users navigate through different pages and components.
  • Interactive elements: Which elements are clickable, scrollable, or otherwise interactive.
  • Data input: How users enter data into forms and other input fields.
  • State changes: How the UI changes in response to user actions.

By understanding these dynamic aspects, Replay AI can generate code that accurately reflects the intended behavior of the UI.

Key Features of Replay AI#

Replay AI offers a comprehensive set of features designed to streamline the UI migration process:

  • Multi-page Generation: Generate code for entire applications, not just single screens. Replay understands page transitions and maintains context across multiple views.
  • Supabase Integration: Seamlessly integrate with Supabase for backend data management. Replay can generate code that interacts with your Supabase database, making it easy to build full-stack applications.
  • Style Injection: Apply custom styles to your generated UI. Replay allows you to inject CSS or other styling code to match your brand's visual identity.
  • Product Flow Maps: Visualize user flows through your application. Replay generates flow diagrams that help you understand how users interact with your UI.
  • Video as Source of Truth: Replay treats the video recording as the single source of truth for the UI. This ensures that the generated code accurately reflects the intended behavior of the UI.

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

Here's a practical guide on how to use Replay AI to migrate a simple UI:

Step 1: Recording Your UI#

Record a video of yourself interacting with the UI you want to migrate. Make sure to capture all the key user flows and interactive elements. Use a screen recording tool like OBS Studio or QuickTime Player.

💡 Pro Tip: Speak clearly while recording to narrate your actions. This can provide additional context for Replay AI and improve the accuracy of the generated code.

Step 2: Uploading the Video to Replay#

Upload the video recording to the Replay AI platform. Replay supports various video formats, including MP4, MOV, and AVI.

Step 3: Configuring Replay AI#

Configure Replay AI by specifying the target framework (e.g., React, Vue.js, Angular) and any other relevant settings. You can also specify your Supabase project details if you want to integrate with Supabase.

Step 4: Generating the Code#

Click the "Generate Code" button to start the code generation process. Replay AI will analyze the video recording and generate the corresponding code. This process may take a few minutes depending on the complexity of the UI.

Step 5: Reviewing and Refining the Code#

Review the generated code and make any necessary adjustments. Replay AI provides a code editor that allows you to easily modify the code.

📝 Note: While Replay AI aims for high accuracy, manual review is always recommended to ensure the generated code meets your specific requirements.

Step 6: Integrating the Code into Your Project#

Integrate the generated code into your existing project. You can copy and paste the code into your code editor or use Replay AI's built-in export feature to export the code as a zip file.

Example: Generating a Simple React Component#

Let's say you recorded a video of yourself interacting with a simple form that allows users to enter their name and email address. Replay AI could generate the following React component:

typescript
// Generated by Replay AI import React, { useState } from 'react'; const UserForm = () => { const [name, setName] = useState(''); const [email, setEmail] = useState(''); const handleSubmit = (event: React.FormEvent) => { event.preventDefault(); console.log('Name:', name); console.log('Email:', email); // Add your form 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 is a fully functional React component that captures user input and handles form submission. You can easily integrate this component into your existing React application.

Integrating with Supabase#

Replay AI can also generate code that integrates with Supabase. For example, if you have a Supabase table called "users," Replay AI could generate code that inserts new users into the table when the form is submitted:

typescript
// Generated by Replay AI with Supabase integration import React, { useState } from 'react'; import { createClient } from '@supabase/supabase-js'; const supabaseUrl = 'YOUR_SUPABASE_URL'; const supabaseKey = 'YOUR_SUPABASE_ANON_KEY'; const supabase = createClient(supabaseUrl, supabaseKey); const UserForm = () => { const [name, setName] = useState(''); const [email, setEmail] = useState(''); const handleSubmit = async (event: React.FormEvent) => { event.preventDefault(); const { data, error } = await supabase .from('users') .insert([{ name, email }]); if (error) { console.error('Error inserting user:', error); } else { console.log('User inserted successfully:', data); } }; 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;

⚠️ Warning: Remember to replace

text
YOUR_SUPABASE_URL
and
text
YOUR_SUPABASE_ANON_KEY
with your actual Supabase credentials. Store your Supabase key securely and avoid committing it to your codebase.

This code demonstrates how Replay AI can simplify the process of integrating your UI with a backend database.
