Use Case

Rebuild UI from Video Recordings

Upload a screen recording of any interface. Replay analyzes the UI behavior over time and reconstructs working code that matches layout, navigation, and interaction states.

The Problem

You need to rebuild an existing interface. Maybe it's a legacy internal tool with no design files. Maybe you're recreating a competitor's UI for reference. Maybe the original team is gone and all you have is the running application.

Traditional approaches fail here. Screenshots capture a single moment. Design files (if they exist) show intent, not reality. AI prompt-based tools generate guesses, not reconstructions.

What you actually need is a tool that can watch the interface work and understand its behavior over time.

How Replay Works

01

Upload or record a video

Screen record the interface you want to rebuild. Navigate through all the screens and states you need.

02

Select the relevant flow

Trim the video to focus on specific sections. Replay analyzes only what you select.

03

Replay analyzes UI behavior

The AI watches the video over time, detecting layouts, navigation patterns, and state changes.

04

Structure, flow, and code are reconstructed

Get working HTML/CSS/JS code that matches the interface shown in the video.

What Replay Copies 1:1

  • Layout hierarchy and component structure
  • Navigation structure and menu items
  • Screen-to-screen transitions
  • Interaction states (hover, active, focus)
  • Responsive behavior (if visible in video)
  • Typography, colors, and spacing

What Replay Does NOT Invent

  • Features not shown in the video
  • Screens that weren't navigated to
  • Business logic or backend functionality
  • Data that wasn't displayed
  • Animations not demonstrated

If it wasn't in the video, it won't be in the code. Trust over hype.

Real Use Cases

Modernizing Internal Admin Dashboards

Record your legacy admin panel and get a modern, responsive version. Replay captures all the data tables, filters, and navigation exactly as they work today.

Rebuilding Legacy CRM Interfaces

That old CRM your team has been using for years? Record the key workflows and get production-ready code that matches the UI your users already know.

Competitive Analysis for MVP

Need to understand how a competitor structured their product? Record a demo video and Replay will reconstruct the UI patterns and navigation flow.

If the UI exists on a screen, Replay can rebuild it from video.
