TL;DR: Replay leverages video analysis and Gemini to reconstruct fully functional chatbot UIs directly from screen recordings of user interactions, saving development time and ensuring accurate representation of desired behavior.
The "screenshot-to-code" revolution is a mirage. Static images offer a glimpse, but they fundamentally fail to capture the dynamic essence of user experience. Building chatbot UIs, in particular, demands understanding user flow, contextual interactions, and subtle behavioral nuances. Screenshots simply can't deliver that. We need to move beyond visual imitation and embrace behavior-driven reconstruction.
Why Video is the New Source Code for Chatbots#
Chatbot UI development is often a tedious cycle of design, implementation, testing, and iteration. Replicating complex conversational flows based on static mockups leads to endless refinements and missed edge cases. What if you could capture a REAL user interacting with a chatbot and directly translate that interaction into working code? That's the power of video-to-code.
Video provides a wealth of information:
- •User Actions: Clicks, taps, scrolls, and form inputs are all clearly visible.
- •Contextual Awareness: The video captures the surrounding UI and application state, providing context for each user action.
- •Temporal Dynamics: The sequence and timing of events reveal the user's intent and decision-making process.
- •Edge Cases: Unexpected user behavior or error scenarios are naturally captured in the video.
Replay harnesses this rich data to reconstruct chatbot UIs with unparalleled accuracy and efficiency. It's not just about recreating pixels; it's about understanding why the user interacted the way they did.
Replay: Behavior-Driven Reconstruction in Action#
Replay employs a novel "Behavior-Driven Reconstruction" approach. It analyzes video recordings of chatbot interactions, leveraging the power of Gemini to understand user intent, extract UI elements, and generate working code. This approach offers several key advantages over traditional screenshot-to-code or manual development:
- •Accuracy: Replay accurately captures complex conversational flows and user interactions, reducing the risk of errors and missed edge cases.
- •Speed: Automated code generation significantly reduces development time, allowing developers to focus on higher-level tasks.
- •Flexibility: Replay can handle a wide range of chatbot UIs and interaction styles.
- •Maintainability: The generated code is clean, well-structured, and easy to maintain.
Understanding the Process#
Replay analyzes the video frame-by-frame, identifying UI elements (buttons, text fields, chat bubbles), user actions (clicks, taps, typing), and application state. This information is then fed into a Gemini-powered engine that understands the relationships between these elements and generates the corresponding code.
The engine considers:
- •UI Element Hierarchy: Understanding the structure of the UI allows Replay to generate semantic and maintainable code.
- •Event Handling: Replay automatically generates event handlers for user actions, such as button clicks and form submissions.
- •Data Binding: Replay infers data binding relationships between UI elements and the underlying data model.
- •Conversational Flow: Replay understands the sequence of interactions and generates code that accurately reflects the chatbot's conversational flow.

Building a Chatbot UI with Replay: A Step-by-Step Guide#
Let's walk through a simplified example of how you can use Replay to create a chatbot UI from a video recording.
Step 1: Record the Interaction#
Record a video of yourself interacting with an existing chatbot UI. This video should showcase the key conversational flows and user interactions you want to replicate. The clearer and more comprehensive the video, the better the results.
💡 Pro Tip: Narrate your actions while recording the video. This provides additional context for Replay and can improve the accuracy of the generated code.
Step 2: Upload to Replay#
Upload the video to the Replay platform. Replay will automatically analyze the video and extract the relevant UI elements and user interactions.
Step 3: Review and Refine#
Review the generated code and make any necessary refinements. Replay provides a visual editor that allows you to easily adjust the UI layout, modify event handlers, and fine-tune the conversational flow.
📝 Note: Replay's AI is constantly learning and improving. The more videos you upload, the more accurate and efficient it becomes.
Step 4: Integrate into Your Project#
Integrate the generated code into your existing project. Replay supports a variety of frameworks and libraries, including React, Vue.js, and Angular.
Example Code#
Here's an example of the type of code that Replay might generate for a simple chatbot UI:
typescript// React component for a chat bubble import React from 'react'; interface ChatBubbleProps { text: string; isUser: boolean; } const ChatBubble: React.FC<ChatBubbleProps> = ({ text, isUser }) => { return ( <div className={`chat-bubble ${isUser ? 'user' : 'bot'}`}> {text} </div> ); }; export default ChatBubble; // Example usage: // <ChatBubble text="Hello, how can I help you?" isUser={false} />
typescript// Example of handling user input and sending a message import React, { useState } from 'react'; import ChatBubble from './ChatBubble'; const ChatInterface = () => { const [messages, setMessages] = useState<Array<{text: string, isUser: boolean}>>([]); const [inputText, setInputText] = useState(''); const handleSendMessage = () => { if (inputText.trim() !== '') { setMessages([...messages, { text: inputText, isUser: true }]); // Simulate bot response (replace with actual API call) setTimeout(() => { setMessages([...messages, { text: `You said: ${inputText}`, isUser: false }]); }, 500); setInputText(''); } }; return ( <div> {messages.map((message, index) => ( <ChatBubble key={index} text={message.text} isUser={message.isUser} /> ))} <input type="text" value={inputText} onChange={(e) => setInputText(e.target.value)} /> <button onClick={handleSendMessage}>Send</button> </div> ); }; export default ChatInterface;
⚠️ Warning: The generated code may require some manual adjustments, especially for complex interactions or custom UI components. Always review and test the code thoroughly before deploying it to production.
