## Outline
### 0:00 REA Is Trending
- **0:00** REA ("Reverse Engineer Anything") is an MCP that lets you virtually rebuild any software: it decompiles the source app and hands your AI agent instructions for recreating its features.
- **0:12** Viral demos: alex funk reverse engineering a gen-1 Apple TV remote in ~45 minutes; someone on X reproducing the Photoshop suite.
- **0:25** Nick's plan: how REA works, why people are "missing the point", and what it means for software.
- **0:40** Reactions: Matthew Berman ("software is done"), "software is dead, long live software", Amjad Masad of Replit ("pretty much all software will soon be open source"), Jaden Williams ("God help us all").
### 1:08 How REA Works
![[images/I-Tested-The-Viral-Github-Repo-To-Reverse-Engineer-Anything-t0120.webp]]
- **1:08** Flow: you ask your agent how a feature works → the agent calls the **REA MCP** → REA drives a tool suite of **Ghidra** (2019), **Hopper** (~2011) and **IDA** (1990s).
- **1:40** The agent can also use **Chrome DevTools** and other services to poke around the app.
- **1:50** Results come back as pseudocode (high-level descriptions), proof of what's happening, and unknowns; the agent loops "like a fat merry-go-round" until the app is rebuilt.
- **2:05** Setup: just tell the agent "go download reverse engineer anything, REA, and let me know when you're done."
### 2:44 Rebuilding Preview
![[images/I-Tested-The-Viral-Github-Repo-To-Reverse-Engineer-Anything-t0220.webp]]
- **2:15** Nick works in **Orca**, a terminal manager that splits panes so he can run Claude in one and Codex in another.
- **2:45** New Claude session: "Use REA to rebuild the Preview app on my Mac." Preview's features: info button, zoom, markup (boxes, handwriting).
- **3:35** Control test in parallel: Claude rebuilds Preview *without* REA.
- **4:00** The REA run decompiles with Ghidra; the two race. Opus without REA finishes first, but its version feels laggy.
### 4:46 Matching the App
![[images/I-Tested-The-Viral-Github-Repo-To-Reverse-Engineer-Anything-t0450.webp]]
- **4:45** After 3–4 more minutes the REA version launches, self-testing by opening and closing tabs.
- **4:55** Side by side with the real Preview it's "virtually the same thing": info, zoom, share, drawing (faster than the non-REA build), rotate, annotate, save.
### 5:26 Not Exactly New
![[images/I-Tested-The-Viral-Github-Repo-To-Reverse-Engineer-Anything-t0540.webp]]
- **5:26** Not a new technology: Ghidra was released by the **NSA** in 2019, Hopper Disassembler's site "looks like it crawled out of the Stone Ages", IDA is older still.
- **5:55** REA's real contribution is a simple interface that gives agents access to these tools.
- **6:10** He hasn't seen strong demos; "the internet has probably gotten a little bit ahead of itself." Mashup game demos (Tony Hawk × Halo 3 × Modern Warfare × RuneScape; his own Minecraft × Attack on Titan game) are more a memetic moment than a breakthrough.
### 6:50 GitHub star hype
![[images/I-Tested-The-Viral-Github-Repo-To-Reverse-Engineer-Anything-t0650.webp]]
- **6:50** Nearly every REA video opens with a GitHub-stars-per-day graph: steady a week ago, explosive the last few days.
- **7:10** If all a video can show is stars, it probably lacks a better demo.
### 7:27 What It Means Next
- **7:35** Most software becomes effectively open source: we've moved up an abstraction layer to general intelligence (Claude, Codex) that rebuilds software on the fly.
- **7:55** Front ends and back ends become highly commoditized; the trend closes many business doors.
- **8:25** Wrapper apps around Claude/Codex (including his own explainer app) get swallowed by model updates; the value ladder has moved.
- **8:45** Selling reverse-engineered clones runs into IP problems; the real change is a lower barrier to recombining ideas (and to trending on X).
- **9:05** You don't need REA: an agent can study a feature from screenshots and replicate it, possibly more efficiently than the human original.
- **9:55** Within a month or two, Claude Code post-training will likely absorb most of this; REA's decompilers mainly add speed, while vanilla agents reach visual parity in maybe 2/3 the time or less.
- **10:30** "Get ready for the reverse engineer era."
