How to actually use REA (Reverse Engineer Anything), the viral GitHub repo that lets Claude Code or Codex look inside an app with no source code and work out how it's built. I pointed it at my own Mac app, HoverSpeech, had Claude rebuild its read-aloud feature as a web app, and put it online with the Hostinger Connector. At the end I share what it cost (about 56 million tokens, roughly $28.60 at API prices, or 2% of my weekly Claude plan) and what I think this means if you build or sell software.

🔍 KEY TAKEAWAYS: • REA connects your coding agent to reverse engineering tools like Ghidra and Hopper and lets it drive them in plain English. • It doesn't give you the original source code. You get the agent's best reconstruction of the logic, the evidence for each claim, and a list of what it couldn't work out. • Setup is one command, or one prompt in Claude Code or Codex. Native Mac apps need Ghidra (free) or Hopper. • Test it fairly: an empty folder, the same download a stranger gets, and no access to your source code. • From the findings, Claude rebuilt the read-aloud feature as a web app and Hostinger Connector put it online. • The whole run used about 56 million tokens, roughly $28.60 at API prices. • Your code isn't what protects your product anymore. Your servers, users, distribution and insights are.

📈 TIPS FOR USING REA: • Only point it at software you own or are allowed to examine. • Ask about one feature at a time, not "rebuild this whole app". • Keep the approval prompts on. REA runs with your permissions. • For simple jobs, a regular coding agent can often do the same work.

If you build apps with AI, the useful part isn't copying anyone. It's learning how good software works and shipping your own.
