TL;DR: Replay uses video analysis to generate a fully functional news website UI, capturing user behavior from video tutorials and translating it into clean, maintainable code.
The future of UI development isn't just about pixels; it's about understanding user intent. Screenshot-to-code tools are a start, but they only capture static representations. What if you could extract the behavior driving a UI's creation, directly from video? That's the power of Replay.
The Problem: Bridging the Gap Between Tutorials and Code#
Learning new UI frameworks or design patterns often involves watching countless video tutorials. You see an expert build a news website, meticulously crafting components, styling, and interactions. But translating that visual knowledge into working code is time-consuming and error-prone. You're essentially re-implementing someone else's work, pixel by pixel.
The challenge is not just replicating the visual appearance, but also understanding the underlying logic and user flow demonstrated in the video. This is where traditional code generation tools fall short. They can't capture the nuances of user behavior or the intent behind each action.
The Solution: Behavior-Driven Reconstruction with Replay#
Replay solves this problem by analyzing video tutorials and reconstructing the UI based on observed user behavior. Instead of simply converting static images, Replay understands what the user is trying to achieve and generates code that reflects that intent. This "Behavior-Driven Reconstruction" approach results in more robust, maintainable, and user-centric UI.
Replay leverages powerful AI models, including Gemini, to process video data, identify UI elements, and infer the interactions between them. This allows it to generate multi-page applications, integrate with backends like Supabase, and even inject custom styles.
Building a News Website UI from a Video Tutorial: A Step-by-Step Guide#
Let's walk through how you can use Replay to generate a news website UI from a video tutorial.
Step 1: Preparing the Video#
The first step is to select a suitable video tutorial. Look for videos that demonstrate the creation of a news website UI, ideally covering multiple pages, components, and interactions. The clearer the video, the better the results.
💡 Pro Tip: Choose videos with clear screen recordings and minimal distractions. A well-structured tutorial will significantly improve Replay's accuracy.
Step 2: Uploading and Analyzing the Video with Replay#
Upload the video to Replay. The platform will then analyze the video, identifying UI elements, interactions, and overall structure. This process may take a few minutes depending on the length of the video.
📝 Note: Replay supports various video formats. Ensure your video is compatible before uploading.
Step 3: Reviewing and Refining the Generated Code#
Once the analysis is complete, Replay will present a generated code preview. This is where you can review the generated code, identify any areas that need refinement, and make adjustments.
typescript// Example: Generated React component for a news article card const ArticleCard = ({ title, description, imageUrl, link }: { title: string; description: string; imageUrl: string; link: string }) => { return ( <a href={link} className="article-card"> <img src={imageUrl} alt={title} className="article-image" /> <div className="article-content"> <h2 className="article-title">{title}</h2> <p className="article-description">{description}</p> </div> </a> ); }; export default ArticleCard;
⚠️ Warning: The initial generated code may require some manual adjustments. Review the code carefully and make necessary changes to ensure it meets your specific requirements.
Step 4: Integrating with Supabase (Optional)#
If the video tutorial demonstrates integration with a backend like Supabase, Replay can automatically generate the necessary code to connect your UI to the database. This includes setting up API endpoints, fetching data, and displaying it in the UI.
typescript// Example: Fetching news articles from Supabase import { createClient } from '@supabase/supabase-js'; const supabaseUrl = 'YOUR_SUPABASE_URL'; const supabaseKey = 'YOUR_SUPABASE_ANON_KEY'; const supabase = createClient(supabaseUrl, supabaseKey); const getArticles = async () => { const { data: articles, error } = await supabase .from('articles') .select('*'); if (error) { console.error('Error fetching articles:', error); return []; } return articles; }; export default getArticles;
Step 5: Injecting Custom Styles#
Replay allows you to inject custom styles into the generated UI. This can be done by providing a CSS file or using inline styles. This allows you to customize the look and feel of the UI to match your brand or design preferences.
css/* Example: Custom styles for the news article card */ .article-card { display: flex; flex-direction: column; border: 1px solid #ccc; border-radius: 8px; overflow: hidden; margin-bottom: 16px; } .article-image { width: 100%; height: 200px; object-fit: cover; } .article-content { padding: 16px; } .article-title { font-size: 1.2rem; margin-bottom: 8px; }
Step 6: Generating Product Flow Maps#
Replay can also generate product flow maps based on the user interactions observed in the video. This provides a visual representation of the user journey through the news website, allowing you to identify potential areas for improvement.
🚀 Pro Tip: Use the generated product flow maps to optimize the user experience and ensure a smooth and intuitive navigation through the news website.

Frequently Asked Questions#
Is Replay free to use?#
Replay offers a free tier with limited features. Paid plans are available for more advanced features and usage. Check the Replay pricing page for the latest details.
How is Replay different from v0.dev?#
v0.dev primarily uses text prompts and existing component libraries to generate UI. Replay, on the other hand, analyzes video tutorials to understand user behavior and reconstruct the UI from scratch. Replay focuses on capturing the process of building a UI, not just the end result.
What types of video tutorials are best suited for Replay?#
The best video tutorials for Replay are those that demonstrate the creation of a UI from start to finish, with clear screen recordings and minimal distractions. Tutorials that cover multiple pages, components, and interactions are ideal.
What frameworks and libraries does Replay support?#
Replay currently supports React, Vue, and Angular. Support for other frameworks and libraries is planned for future releases.
How accurate is the generated code?#
The accuracy of the generated code depends on the quality of the video tutorial and the complexity of the UI. While Replay strives to generate accurate code, some manual refinement may be required.
