Struggling to Integrate Custom Components from Video? Replay AI Automates the Process in 2026

TL;DR: Stop manually transcribing video of custom component interactions into code – Replay AI uses behavior-driven reconstruction to automate the entire process, understanding user intent and generating functional UI.

Integrating custom components from video demos or tutorials has always been a pain. You watch someone skillfully navigate their application, showcasing unique UI elements and intricate workflows, but translating that visual information into working code is a tedious, error-prone process. Screenshot-to-code tools offer a partial solution, but they lack the crucial understanding of why the user is interacting with the UI in a specific way. They see the static image, not the dynamic behavior. This is where Replay changes the game.

The Problem: Manual Transcription is a Time Sink#

Let's face it: replicating a custom component from a video is like trying to assemble IKEA furniture without the instructions. You see the finished product, but the path to get there is obscured by guesswork and frustration. You pause, rewind, and meticulously transcribe the actions, hoping to capture the essence of the interaction. This process is not only time-consuming but also prone to errors, especially when dealing with complex state management or asynchronous operations. The result? A codebase littered with bugs and a significant delay in your development timeline.

Furthermore, traditional methods struggle with:

• •Dynamic Data: Videos often showcase data fetched from APIs or generated dynamically. Static screenshots can't capture this.
• •Complex Interactions: Drag-and-drop, animations, and other intricate interactions are nearly impossible to accurately recreate from a single image.
• •Contextual Understanding: Knowing why a user performs a specific action is critical for correct implementation. Screenshots offer no insight into user intent.

Replay: Behavior-Driven Reconstruction#

Replay tackles this problem head-on by employing behavior-driven reconstruction. Instead of relying on static screenshots, Replay analyzes the video itself, extracting not just the visual elements but also the underlying user behavior. By leveraging Gemini's advanced video understanding capabilities, Replay can identify UI components, track user interactions, and infer the intended functionality. This allows Replay to generate code that accurately reflects the dynamic nature of the application being demonstrated in the video.

How Replay Works#

Replay's core strength lies in its ability to go beyond visual recognition. It understands the flow of the application, the purpose of each interaction, and the relationship between different components. This is achieved through a multi-stage process:

1. •Video Analysis: Replay analyzes the video to identify UI elements, track user actions (clicks, scrolls, keyboard inputs), and detect state changes.
2. •Behavior Inference: Using AI, Replay infers the user's intent behind each action. For example, it can distinguish between a deliberate click and an accidental tap.
3. •Code Generation: Based on the inferred behavior, Replay generates clean, functional code that replicates the observed UI and interactions.
4. •Integration & Customization: Replay provides tools for seamlessly integrating the generated code into your existing project, including style injection and data binding.

Key Features That Set Replay Apart#

Replay isn't just another screenshot-to-code tool. It's a complete solution for transforming video into working UI, offering a range of features designed to streamline the development process:

• •Multi-Page Generation: Replay can analyze videos that span multiple pages or views, generating code for the entire application flow.
• •Supabase Integration: Seamlessly connect your generated UI to a Supabase backend for data persistence and real-time updates.
• •Style Injection: Replay can extract and apply styles from the video, ensuring that the generated UI matches the visual appearance of the original application.
• •Product Flow Maps: Visualize the user flow captured in the video, providing a clear overview of the application's functionality.

Tutorial: Integrating a Custom Date Picker from Video#

Let's walk through a practical example of how to use Replay to integrate a custom date picker component from a video tutorial.

Step 1: Upload the Video#

Upload the video tutorial to the Replay platform. Replay supports various video formats and resolutions.

Step 2: Analyze the Video#

Replay will automatically analyze the video, identifying the date picker component and tracking the user's interactions with it. This includes selecting dates, navigating between months, and applying custom styles.

Step 3: Review and Refine#

Review the generated code and make any necessary adjustments. Replay provides a visual editor that allows you to fine-tune the UI and interactions.

Step 4: Integrate into Your Project#

Download the generated code and integrate it into your React, Vue, or Angular project. Replay provides clear instructions and code snippets for seamless integration.

Here's an example of the code Replay might generate for a simple React date picker component:

typescript
// Generated by Replay AI
import React, { useState } from 'react';
import './DatePicker.css'; // Extracted styles

interface DatePickerProps {
  onDateSelect: (date: Date) => void;
}

const DatePicker: React.FC<DatePickerProps> = ({ onDateSelect }) => {
  const [selectedDate, setSelectedDate] = useState(new Date());

  const handleDateClick = (day: number) => {
    const newDate = new Date(selectedDate);
    newDate.setDate(day);
    setSelectedDate(newDate);
    onDateSelect(newDate);
  };

  // ... (Calendar logic and rendering) ...

  return (
    <div className="date-picker">
      {/* Calendar UI elements */}
      <button onClick={() => handleDateClick(1)}>1</button>
      {/* ... */}
    </div>
  );
};

export default DatePicker;

💡 Pro Tip: Use high-quality videos with clear demonstrations for optimal results with Replay.

Benefits of Using Replay#

• •Significant Time Savings: Automate the tedious process of manually transcribing video into code, freeing up your time for more critical tasks.
