Replay AI: Build video with React scale and quality for a solid UI component.

TL;DR: Replay AI empowers developers to reconstruct fully functional React UI components from video recordings, enabling rapid prototyping and consistent user experience replication.

From Screen Recording to Production-Ready React: The Replay AI Revolution#

The traditional UI development process is often a bottleneck. Translating designs, user flows, and desired behaviors into code can be time-consuming and error-prone. What if you could simply record a user interacting with an existing interface and have that interaction transformed into a working, scalable React component? That's the power of Replay AI.

Replay AI isn't just another screenshot-to-code tool. It leverages Gemini to analyze video, understanding the intent behind user actions and translating them into robust, behavior-driven React components. This "Behavior-Driven Reconstruction" approach ensures that the generated code accurately reflects the desired user experience, leading to faster development cycles and more consistent UIs.

Why Video Analysis Matters: Beyond Static Images#

Screenshot-to-code tools often struggle with dynamic elements, animations, and complex interactions. They capture a single frame in time, missing the crucial context of how a user interacts with the interface. Replay AI, on the other hand, analyzes video, enabling it to:

• •Understand state changes and transitions
• •Replicate animations and dynamic styling
• •Capture user input and form interactions
• •Reconstruct multi-page flows

This deeper understanding translates into more accurate and functional code generation.

Replay AI in Action: A Practical Example#

Let's say you want to replicate a specific product flow from a competitor's website. Instead of manually recreating the UI from scratch, you can simply record a video of the flow using your browser and feed it to Replay AI. Replay will then generate the corresponding React code, complete with styling and event handlers.

Step 1: Capture the User Flow#

Record a video of the desired user flow, ensuring that all relevant interactions are captured. This could include navigating between pages, filling out forms, clicking buttons, and interacting with dynamic elements.

Step 2: Upload to Replay#

Upload the video to the Replay AI platform. Replay will automatically analyze the video and begin reconstructing the UI.

Step 3: Review and Refine the Generated Code#

Once the reconstruction is complete, Replay will present you with the generated React code. You can review the code, make any necessary adjustments, and integrate it into your project.

typescript
// Example of generated React code for a simple form
import React, { useState } from 'react';

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

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

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

export default GeneratedForm;

💡 Pro Tip: The quality of the generated code depends on the clarity of the video. Ensure that the video is well-lit and that the user interactions are clearly visible.

Multi-Page Generation and Product Flow Maps#

Replay AI goes beyond single-component generation. It can reconstruct entire multi-page flows, capturing the relationships between different components and pages. This is particularly useful for replicating complex user journeys, such as e-commerce checkout flows or onboarding processes.

Replay also generates "Product Flow maps" which visually represent the reconstructed user flow, making it easier to understand and modify the generated code.

Key Features of Replay AI#

• •Video Input: Analyzes video recordings to understand user behavior.
• •Behavior-Driven Reconstruction: Focuses on recreating the intent behind user actions, not just the visual appearance.
• •Multi-Page Generation: Reconstructs entire multi-page flows.
• •Supabase Integration: Seamlessly integrates with Supabase for data persistence and authentication.
• •Style Injection: Replicates the styling of the original UI, ensuring visual consistency.
• •Product Flow Maps: Generates visual representations of the reconstructed user flow.

Replay AI vs. Traditional Methods and Other Tools#

⚠️ Warning: While Replay AI can significantly accelerate the UI development process, it's important to review and refine the generated code to ensure that it meets your specific requirements.

Advanced Techniques: Style Injection and Supabase Integration#

Replay AI allows for advanced customization through style injection and Supabase integration.

Style Injection#

You can inject custom CSS or styling libraries into the generated components, allowing you to fine-tune the visual appearance of the UI. This is particularly useful for ensuring that the generated components match your existing design system.

Supabase Integration#

Replay AI can automatically generate Supabase client code for interacting with your database. This simplifies the process of fetching and updating data in your React components.

typescript
// Example of generated Supabase client code
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = process.env.NEXT_PUBLIC_SUPABASE_URL;
const supabaseKey = process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY;

export const supabase = createClient(supabaseUrl, supabaseKey);

export const fetchProducts = async () => {
  const { data, error } = await supabase
    .from('products')
    .select('*');

  if (error) {
    console.error('Error fetching products:', error);
    return [];
  }

  return data;
};

📝 Note: Ensure that you have properly configured your Supabase credentials before using the generated client code.

Benefits of Using Replay AI#

• •Accelerated Development: Reconstruct UIs in minutes instead of hours.
• •Improved Accuracy: Capture the intent behind user interactions for more accurate code generation.
• •Enhanced Collaboration: Share video recordings and generated code with your team for seamless collaboration.
• •Consistent User Experience: Replicate existing UIs with pixel-perfect accuracy.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited usage. Paid plans are available for higher usage and access to advanced features. Check the Replay pricing page for details.

How is Replay different from v0.dev?#

While v0.dev uses text prompts to generate UI components, Replay AI uses video recordings. This allows Replay to capture the dynamic aspects of user interactions and generate more accurate and functional code. Replay focuses on "Behavior-Driven Reconstruction" compared to v0's prompt-based generation.

What types of videos can Replay analyze?#

Replay can analyze any video recording of a user interacting with a website or application. The video should be clear and well-lit, with all relevant interactions clearly visible.

What frameworks does Replay support?#

Currently, Replay primarily focuses on React. Support for other frameworks is planned for future releases.
