TL;DR: Replay uses video analysis and behavior-driven reconstruction to generate a fully functional React CRM dashboard, complete with Supabase integration and dynamic styling, directly from a screen recording.
Recreating complex user interfaces has always been a bottleneck in software development. Screenshot-to-code tools offer a partial solution, but they often fall short when dealing with dynamic elements, intricate user flows, and multi-page applications. They capture the appearance but miss the intent. In 2026, the landscape has shifted. We're beyond static representations. We're talking about behavior-driven code generation.
Enter Replay.
Replay leverages advanced video analysis and Gemini's AI capabilities to understand user behavior as captured in screen recordings. Instead of simply converting pixels to code, Replay reconstructs the underlying logic, data flow, and user interactions. This means you can take a video of someone using a CRM dashboard and, with Replay, generate a working React application, complete with data connections and dynamic styling.
Understanding Behavior-Driven Reconstruction#
The core innovation behind Replay lies in its "Behavior-Driven Reconstruction" approach. Unlike traditional methods that treat UI elements as static objects, Replay analyzes the actions performed in the video. It identifies patterns, understands data dependencies, and infers the intended functionality.
Consider a user clicking through a CRM dashboard:
- •They navigate to a specific customer profile.
- •They update the customer's contact information.
- •They add a note to the customer's record.
A screenshot-to-code tool would only capture the visual state of each screen. Replay, on the other hand, understands the sequence of actions and the data being manipulated. This allows it to generate code that accurately reflects the user's intent.
Recreating a CRM Dashboard: A Step-by-Step Guide#
Let's walk through the process of recreating a complex CRM dashboard from a video using Replay.
Step 1: Upload and Analyze the Video#
The first step is to upload your screen recording to Replay. The platform supports various video formats and resolutions. Once uploaded, Replay's AI engine begins analyzing the video, identifying UI elements, user interactions, and data flows.
💡 Pro Tip: Ensure your video is clear and stable. Consistent lighting and minimal background noise will improve Replay's accuracy.
Step 2: Define the Scope and Data Sources#
Next, you'll define the scope of the reconstruction. This involves specifying which sections of the video should be converted into code and identifying the relevant data sources. In the case of a CRM dashboard, this might include specifying the customer list, profile details, and activity logs.
Replay seamlessly integrates with Supabase, allowing you to connect your generated application to a real-time database. You can define the data schemas and relationships within the Replay interface.
Step 3: Configure Styling and Theming#
Replay allows you to inject custom styles and themes into your generated application. You can use CSS, Tailwind CSS, or any other styling framework. This ensures that the reconstructed dashboard matches your desired look and feel.
📝 Note: Replay automatically detects and applies existing styles from the video, but you can always override them with your own custom styles.
Step 4: Generate the React Code#
With the video analyzed, scope defined, and styles configured, you're ready to generate the React code. Replay uses Gemini to create clean, well-structured code that is easy to understand and maintain.
Here's an example of the generated code for a customer profile component:
typescript// CustomerProfile.tsx import React, { useState, useEffect } from 'react'; import { supabase } from './supabaseClient'; // Assuming Supabase integration interface Customer { id: string; name: string; email: string; phone: string; } const CustomerProfile: React.FC<{ customerId: string }> = ({ customerId }) => { const [customer, setCustomer] = useState<Customer | null>(null); const [loading, setLoading] = useState<boolean>(true); useEffect(() => { const fetchCustomer = async () => { setLoading(true); const { data, error } = await supabase .from('customers') .select('*') .eq('id', customerId) .single(); if (error) { console.error('Error fetching customer:', error); } else { setCustomer(data as Customer); } setLoading(false); }; fetchCustomer(); }, [customerId]); if (loading) { return <div>Loading...</div>; } if (!customer) { return <div>Customer not found.</div>; } return ( <div> <h2>{customer.name}</h2> <p>Email: {customer.email}</p> <p>Phone: {customer.phone}</p> {/* Add more customer details here */} </div> ); }; export default CustomerProfile;
This code snippet demonstrates how Replay integrates with Supabase to fetch customer data and display it in a React component. The component is dynamically updated based on the
customerIdStep 5: Review and Refine#
Once the code is generated, you can review it in the Replay editor. This allows you to make any necessary adjustments, such as fixing minor errors or optimizing the code for performance.
⚠️ Warning: While Replay strives for accuracy, it's essential to review the generated code to ensure it meets your specific requirements.
Key Features of Replay#
Replay offers a range of features that make it a powerful tool for UI reconstruction:
- •Multi-page Generation: Replay can generate code for entire applications, including multiple pages and complex navigation flows.
- •Supabase Integration: Seamlessly connect your generated application to a real-time Supabase database.
- •Style Injection: Customize the look and feel of your application with CSS, Tailwind CSS, or any other styling framework.
- •Product Flow Maps: Visualize the user flows captured in the video, making it easier to understand the application's logic.
- •Behavior Analysis: Understand user intent and reconstruct the underlying functionality, not just the visual appearance.
