Replay AI: The Only Tool You Need To Convert Video To Pixel-Perfect UI

TL;DR: Replay AI leverages video analysis and behavior-driven reconstruction to generate fully functional, pixel-perfect UI code, setting it apart from traditional screenshot-to-code solutions.

The promise of AI-powered code generation has always been tantalizing: transform ideas into reality with minimal manual coding. Screenshot-to-code tools have made strides, but they often fall short, producing static interfaces that lack true interactivity and fail to capture the user's intended flow. Replay AI solves this problem by analyzing video of user interactions, understanding the behavior behind the clicks and taps, and reconstructing a fully functional UI.

Understanding Behavior-Driven Reconstruction#

Traditional screenshot-to-code tools treat UI as a static image. They can identify elements like buttons and text fields, but they don't understand the relationships between those elements or the intent behind user actions. This leads to code that might look right but doesn't work right.

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

• •Identify the sequence of user actions: clicks, scrolls, form submissions, etc.
• •Infer the user's intent: what they were trying to accomplish.
• •Reconstruct the UI with the correct event handlers and data bindings.

This "Behavior-Driven Reconstruction" is what allows Replay AI to generate code that is not only pixel-perfect but also fully functional and interactive.

Key Features of Replay AI#

Replay AI isn't just about converting video to code; it's about understanding the user experience and translating that understanding into working UI. Key features include:

• •Multi-page generation: Replay AI can analyze videos that span multiple pages or screens, reconstructing entire product flows.
• •Supabase integration: Seamlessly connect your generated UI to a Supabase backend for data storage and retrieval.
• •Style injection: Replay AI can extract and apply styles from the video, ensuring a consistent look and feel.
• •Product Flow maps: Visualize the user journey captured in the video, providing valuable insights into user behavior.

Replay AI in Action: A Practical Example#

Let's say you have a video recording of a user interacting with a simple to-do list application. The user adds a new task, marks it as complete, and then deletes it. Here's how Replay AI would handle this:

Step 1: Upload the Video to Replay AI#

Simply upload the video file to the Replay AI platform. The AI engine will begin analyzing the video, identifying UI elements and user interactions.

Step 2: Review the Generated Code#

Replay AI generates clean, well-structured code that you can easily customize and integrate into your existing project. For example, the code for adding a new task might look something like this:

typescript
// Example React component generated by Replay AI
import React, { useState } from 'react';

const TodoList = () => {
  const [todos, setTodos] = useState([]);
  const [newTask, setNewTask] = useState('');

  const handleAddTask = () => {
    if (newTask.trim() !== '') {
      setTodos([...todos, { id: Date.now(), text: newTask, completed: false }]);
      setNewTask('');
    }
  };

  return (
    <div>
      <input
        type="text"
        value={newTask}
        onChange={(e) => setNewTask(e.target.value)}
        placeholder="Add new task"
      />
      <button onClick={handleAddTask}>Add</button>
      <ul>
        {todos.map((todo) => (
          <li key={todo.id}>
            <input
              type="checkbox"
              checked={todo.completed}
              onChange={() => {
                // Toggle completion status
                setTodos(
                  todos.map((t) =>
                    t.id === todo.id ? { ...t, completed: !t.completed } : t
                  )
                );
              }}
            />
            <span>{todo.text}</span>
          </li>
        ))}
      </ul>
    </div>
  );
};

export default TodoList;

💡 Pro Tip: Replay AI allows you to fine-tune the generated code, specifying the target framework (React, Vue, etc.) and styling conventions.

Step 3: Integrate with Supabase (Optional)#

If you want to persist the to-do list data, you can easily integrate the generated code with Supabase. Replay AI can automatically generate the necessary API calls and data bindings.

typescript
// Example Supabase integration (requires Supabase client setup)
import { createClient } from '@supabase/supabase-js';

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

const TodoList = () => {
  const [todos, setTodos] = useState([]);

  useEffect(() => {
    fetchTodos();
  }, []);

  const fetchTodos = async () => {
    const { data, error } = await supabase
      .from('todos')
      .select('*');

    if (error) {
      console.error('Error fetching todos:', error);
    } else {
      setTodos(data);
    }
  };

  // ... (rest of the component)
};
