Replay: The AI-Powered UI Solution for Every Project

TL;DR: Replay uses video analysis and AI to reconstruct working UI code, understanding user behavior for faster and more accurate development than screenshot-based tools.

Replay: The AI-Powered UI Solution for Every Project#

Tired of painstakingly translating mockups and user flows into functional code? The traditional process is slow, error-prone, and often misses the nuances of real user interactions. Screenshot-to-code solutions offer a slight improvement, but they only capture static images, not dynamic behavior. What if you could capture the essence of user intent directly from video and automatically generate working UI code?

That's the power of Replay.

Replay is a revolutionary video-to-code engine that leverages the power of Gemini to reconstruct working UI from screen recordings. Instead of relying on static screenshots, Replay analyzes video to understand user behavior and intent, leading to more accurate and functional code generation. We call it Behavior-Driven Reconstruction.

The Problem with Traditional UI Development#

The typical UI development workflow looks something like this:

1. •Design mockups in Figma or Sketch.
2. •Create interactive prototypes.
3. •Record user testing sessions.
4. •Manually translate prototypes and user feedback into code.

This process is fraught with problems:

• •Time-consuming: Manually coding UI elements is a significant time sink.
• •Error-prone: Human error is inevitable when translating designs to code.
• •Incomplete: Static mockups often fail to capture the dynamic nature of user interactions.
• •Difficult to iterate: Making changes based on user feedback requires significant rework.

Screenshot-to-code tools attempt to address some of these issues, but they fall short because they only capture a snapshot of the UI. They don't understand the why behind user actions.

Introducing Replay: Video as the Source of Truth#

Replay takes a different approach. By analyzing video recordings of user interactions, Replay can:

• •Understand user intent and behavior.
• •Reconstruct the UI with greater accuracy.
• •Generate functional code that reflects real-world usage.
• •Create multi-page applications from single video flows.

💡 Pro Tip: Recording clear, high-quality videos is crucial for Replay to accurately interpret user behavior. Minimize distractions on the screen and speak clearly while demonstrating the desired flow.

Key Features of Replay#

Replay offers a range of features designed to streamline UI development:

• •Multi-page Generation: Replay can automatically generate multi-page applications from a single video recording, understanding the flow of user interactions across different screens.
• •Supabase Integration: Seamlessly integrate your generated UI with Supabase for backend functionality, including authentication, data storage, and real-time updates.
• •Style Injection: Customize the look and feel of your UI with style injection, allowing you to apply your brand's unique aesthetic.
• •Product Flow Maps: Visualize the user journey with automatically generated product flow maps, providing valuable insights into user behavior.
• •Behavior-Driven Reconstruction: Replay understands WHAT users are trying to do, not just what they see. This leads to more accurate and functional code.

How Replay Works: A Step-by-Step Guide#

Here's a simplified example of how you can use Replay to generate UI code:

Step 1: Record a Video

Record a video of yourself interacting with a prototype or a similar application. Demonstrate the desired user flow, including clicks, form submissions, and page transitions.

Step 2: Upload to Replay

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

Step 3: Review and Refine

Review the generated code and make any necessary refinements. Replay provides a user-friendly interface for editing the code and adjusting the UI.

Step 4: Integrate with Your Project

Integrate the generated code into your project. Replay supports a variety of frameworks and libraries, including React, Vue.js, and Angular.

Code Example: Generating a Simple Form#

Let's say you record a video of yourself filling out a simple form. Replay can generate the following React code:

typescript
// Generated by Replay
import React, { useState } from 'react';

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

  const handleSubmit = (e) => {
    e.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 SimpleForm;

This is just a simple example, but it demonstrates the power of Replay to automatically generate functional code from video recordings.

Replay vs. Screenshot-to-Code Tools#

How does Replay compare to traditional screenshot-to-code tools? Here's a detailed comparison:

As you can see, Replay offers significant advantages over screenshot-to-code tools, particularly in its ability to understand user behavior and generate dynamic UI code.

Addressing Common Concerns#

Here are some common concerns about video-to-code solutions and how Replay addresses them:

• •Privacy: Replay prioritizes user privacy. Video recordings are processed securely and can be deleted at any time.
• •Accuracy: Replay uses advanced AI algorithms to ensure high accuracy in code generation. However, manual review and refinement may still be necessary.
• •Complexity: Replay is designed to be user-friendly, with a simple and intuitive interface.
• •Security: Replay uses industry-standard security measures to protect user data.

⚠️ Warning: While Replay significantly speeds up the development process, it's important to remember that it's a tool to assist developers, not replace them entirely. Manual review and refinement of the generated code are always recommended.

Supabase Integration: Building Full-Stack Applications#

Replay's seamless integration with Supabase allows you to quickly build full-stack applications. By connecting Replay to your Supabase project, you can automatically generate code that interacts with your database, handles authentication, and provides real-time updates.

For example, if you record a video of yourself creating a new user account, Replay can generate the following code to interact with Supabase:

typescript
// Generated by Replay - Supabase Integration
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = 'YOUR_SUPABASE_URL';
const supabaseKey = 'YOUR_SUPABASE_ANON_KEY';
const supabase = createClient(supabaseUrl, supabaseKey);

const createUser = async (email, password) => {
  const { data, error } = await supabase.auth.signUp({
    email: email,
    password: password,
  });

  if (error) {
    console.error('Error creating user:', error);
  } else {
    console.log('User created successfully:', data);
  }
};

// Example usage (replace with values from your form)
createUser('test@example.com', 'password123');

This code snippet demonstrates how Replay can automatically generate code that interacts with the Supabase authentication API.
