So this came up in yesterday's VIP call with @Ry Mac . @Erick Holliday brought Reverse Engineer Anything (REA) up since there has been a lot of noise around this GitHub repo. My advice is to be careful with it. What REA is A repo that points an AI agent at any app (desktop app, Chrome extension, website) and explains how it works inside: what it calls, where it stores things, how a feature is built. Why I said be careful The first time, I ran it straight on my Mac, against Granola. That gave a package with a single maintainer full access to my computer, with my API keys sitting in the environment. Not a risk I'm taking again. The part most people miss You often don't need the tool at all. The value is the process: 1. Pick one feature you like ("how does Loom have the link ready the second I stop?") 2. Ask Claude to find the app's files on your computer and explain how that feature works 3. Ask it to show you where in the code it found that, so you know it's not guessing 4. Decide if it's worth building your own version A Chrome extension ships its code readable, so for Loom I didn't need a decomplier... plain Claude was enough. What I found: Loom cuts your recording into 4-second pieces and uploads them while you're still recording (that's why the link is ready instantly), and it quietly logs every click and page you visit, timestamped to the video. That log is exactly what you need to turn a recording into an SOP, so I built my own small recorder for my customers (screenshot below). I created this "Risks of REA" document in case you want to dig in deeper https://claude.ai/artifact/9mKjeLWoqpvSanoP4siMP5
