How to Recreate an Online Learning Platform from Video to Next.js with Replay (2026)

TL;DR: Replay leverages video analysis and AI to automatically reconstruct a fully functional Next.js-based online learning platform, including multi-page navigation, Supabase integration for user data, and dynamic styling, all from a simple screen recording.

The era of manual UI recreation is over. Traditional screenshot-to-code tools fall short because they only understand static visuals, not user behavior or intent. Imagine trying to rebuild an interactive learning platform from just images – you'd miss crucial details like navigation flows, form submissions, and dynamic content updates. This is where Replay changes the game.

Rebuilding an Online Learning Platform: The Replay Advantage#

Replay uses "Behavior-Driven Reconstruction." It analyzes video recordings to understand the actions taken within the UI, not just its appearance. This allows Replay to generate code that accurately reflects the intended functionality, resulting in a working application, not just a static mockup. We'll walk through how Replay can recreate an online learning platform from a simple video demo, leveraging Next.js, Supabase, and dynamic styling.

The Challenge: From Video to Functional Code#

Recreating a modern online learning platform involves several complex elements:

• •Multi-page Navigation: Courses, lessons, user profiles, and admin dashboards all require seamless navigation.
• •User Authentication: Securely managing user accounts and access control is critical.
• •Dynamic Content: Lesson content, progress tracking, and personalized recommendations need to be dynamically rendered.
• •Database Integration: Storing user data, course information, and progress requires a robust database solution.
• •Responsive Design: The platform must be accessible on various devices, from desktops to mobile phones.

Traditional methods require manually coding each component, setting up routing, configuring databases, and implementing authentication. This process can take weeks or even months. Replay automates this entire process, significantly reducing development time and effort.

The Replay Solution: Behavior-Driven Reconstruction in Action#

Replay analyzes video input and generates code based on observed user behavior. It identifies UI elements, user interactions, and data flows, and then reconstructs the application using Next.js for the frontend, Supabase for the backend, and dynamically injected styles for a polished look.

Step-by-Step Guide: Recreating the Learning Platform with Replay#

Let's walk through the process of recreating an online learning platform from a video using Replay.

Step 1: Recording the Demo Video#

The first step is to record a clear and comprehensive video demonstration of the online learning platform. This video should showcase all the key features and functionalities, including:

• •Navigating between different pages (courses, lessons, profile, etc.)
• •Creating and managing user accounts
• •Enrolling in courses
• •Completing lessons and quizzes
• •Viewing progress and statistics
• •Administering the platform (if applicable)

💡 Pro Tip: Ensure the video is well-lit and the UI elements are clearly visible. Speak clearly and explain the actions being performed.

Step 2: Uploading the Video to Replay#

Once the video is recorded, upload it to Replay. Replay will automatically analyze the video and begin the reconstruction process. This may take a few minutes, depending on the length and complexity of the video.

Step 3: Reviewing and Refining the Generated Code#

After the reconstruction process is complete, Replay will generate a Next.js project with all the necessary components, pages, and API endpoints. Review the generated code to ensure it accurately reflects the intended functionality.

typescript
// Example: Generated Next.js page for a course details page
import { useRouter } from 'next/router';
import { useEffect, useState } from 'react';
import { supabase } from '../utils/supabaseClient'; // Assuming Supabase setup

const CourseDetails = () => {
  const router = useRouter();
  const { courseId } = router.query;
  const [course, setCourse] = useState(null);

  useEffect(() => {
    const fetchCourse = async () => {
      if (courseId) {
        const { data, error } = await supabase
          .from('courses')
          .select('*')
          .eq('id', courseId)
          .single();

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

    fetchCourse();
  }, [courseId]);

  if (!course) {
    return <div>Loading...</div>;
  }

  return (
    <div>
      <h1>{course.title}</h1>
      <p>{course.description}</p>
      {/* Display lessons, quizzes, etc. */}
    </div>
  );
};

export default CourseDetails;

Replay will also generate Supabase schemas and functions based on the observed data interactions in the video.

Step 4: Customizing the UI and Adding Additional Features#

While Replay automates the core reconstruction process, you may need to customize the UI and add additional features to fully meet your specific requirements. This can involve:

• •Modifying the generated CSS styles to match your brand identity.
• •Adding new components or pages to extend the platform's functionality.
• •Integrating with third-party services or APIs.
• •Implementing more complex business logic.

📝 Note: Replay provides a solid foundation for your application. Customization allows you to tailor it to your exact needs.

Step 5: Deploying the Platform#

Once you are satisfied with the reconstructed platform, you can deploy it to a hosting provider like Vercel or Netlify. Replay generates a standard Next.js project, making deployment straightforward.

Key Features of Replay for Online Learning Platform Reconstruction#

Replay offers several key features that make it ideal for recreating online learning platforms from video:

• •Multi-Page Generation: Replay automatically identifies and generates all the necessary pages for the platform, including courses, lessons, user profiles, and admin dashboards.
• •Supabase Integration: Replay seamlessly integrates with Supabase, a popular open-source Firebase alternative, for user authentication, data storage, and real-time updates.
• •Style Injection: Replay dynamically injects styles based on the video, ensuring the reconstructed platform looks visually appealing and consistent with the original design.
• •Product Flow Maps: Replay generates visual maps of user flows, making it easy to understand how users navigate the platform and identify potential areas for improvement.

Addressing Common Concerns#

Concern: How accurate is the generated code?

Replay uses advanced AI algorithms to analyze video and generate code with high accuracy. However, it's essential to review and refine the generated code to ensure it accurately reflects the intended functionality.

Concern: Can Replay handle complex interactions and animations?

Replay is designed to handle a wide range of UI interactions and animations. However, extremely complex animations may require manual adjustments.

Concern: Does Replay support different UI frameworks?

Currently, Replay primarily supports Next.js for frontend development. Support for other frameworks is planned for future releases.

Frequently Asked Questions#

Is Replay free to use?#

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

How is Replay different from v0.dev?#

v0.dev focuses on generating UI components from text prompts. Replay, on the other hand, analyzes video recordings to reconstruct entire applications, including multi-page navigation, database integration, and dynamic styling. Replay understands behavior, not just aesthetics.

What type of videos work best with Replay?#

Videos with clear UI elements, well-lit environments, and spoken explanations of the actions being performed generally produce the best results.

Can I use Replay to recreate mobile apps?#

Replay is primarily designed for web applications. Support for mobile app reconstruction is under consideration for future releases.

What if the generated code contains errors?#

The generated code is a starting point. It's expected that developers will review and refine the code to ensure it meets their specific requirements. Replay significantly accelerates the development process, but it doesn't eliminate the need for human oversight.
