How To Use REA To Clone Any Software In Minutes

Summary

The video introduces Reverse Engineer Anything (REA), a toolkit that helps AI coding agents inspect existing software and gather evidence about how it works. The goal is to help agents build closer reproductions of desktop, web, mobile, and game applications.

How REA Works

REA is described as an AI-agent skill that coordinates tools for examining applications. For desktop apps, the video highlights Hopper for binary analysis and disassembly. Other tools or integrations may support browser-based and mobile-app analysis.

By gathering context from the application and its program files—not just a written specification—REA aims to help agents produce more accurate implementations.

Setup Guide

The presenter demonstrates the following setup process:

1. Check the installed Node.js version with node -v. The video says REA requires a version above 24.
2. If needed, upgrade Node.js with brew upgrade node.
3. Run REA’s installation command in a terminal.
4. Select an AI agent. The presenter chooses Claude Code and Codex, while noting that other agents may also work.
5. Install Hopper and approve the requested setup changes, including the analysis tools and agent skills.

The subtitles do not provide the full REA installation command.

Clone Demonstration: Wispr Flow

The presenter uses Claude Code and REA to inspect Wispr Flow, a desktop voice-to-text app, and create a smaller working recreation. The demonstrated version includes:

• A hotkey to start recording and transcription.
• Speech transcription, including an example mixing English and Chinese.
• A notepad view containing earlier notes, transcripts, or summaries.
• Local transcription, which the presenter says keeps audio from going online.
• Fast transcription in the demo.

The presenter describes the result as an exact copy, though the demonstration shows a working version rather than a detailed feature-by-feature comparison.

Broader Analysis

The presenter argues that AI-assisted reverse engineering could make software code less of a competitive moat, shifting the advantage toward brand, users, and real-world data.

The video also mentions a viral project said to recreate Adobe-style applications in Rust as an example of how quickly software interfaces and features may be reproduced.
