I installed it the safe way, then used it to build 3 of my own apps from 3 free, open-source tools: a screen recorder with a built-in editor, a screenshot markup tool, and a dictation + meeting-notes app. 🎁 The guide + prompts from this video (free Vibe Coding Incubator community): https://portal.vcinc.ai/communities/groups/vibe-coding-incubator/home/posts/6ad258488a4d7fc13cff8842 🛡️ Before you install ANY skill or repo, watch this: https://youtu.be/I3tOdyD45fs ⚙️ My Claude Code install video: https://youtu.be/lv1lQhcHWbI 🧰 6 Claude Code GitHub repos I use every day: https://youtu.be/L2JKgj7WzU4 🔧 What I used REA, Reverse Engineer Anything (free, MIT license; the ONLY official repo): https://github.com/morluto/rea App 1 started from ShareX (free, GPL-3.0): https://github.com/ShareX/ShareX App 2 started from Greenshot (free, GPL-3.0): https://github.com/greenshot/greenshot App 3 started from OpenWhispr (free, MIT): https://github.com/OpenWhispr/openwhispr Claude Code (in VS Code): https://claude.ai/download Lovable (builds the app for you): https://lovable.dev/?via=nuno-tavares 🤖 Join our Claude Code Workshop here: https://go.vcinc.ai/claudecode 🚀 Join the Vibe Coding Incubator community: https://vcinc.ai/ ⏱️ CHAPTERS 0:00 I built my own screen recorder with REA 0:23 Why everyone is talking about REA 0:51 What REA actually does (the locksmith idea) 2:20 Is software dead?

You get its best reconstruction plus the evidence, not the app's original source code. • Only github.com/morluto/rea is official. Copycat repos with "free download" pages keep popping up. Don't use them. • Install it into ONE project folder and have Claude scan it first. Don't run a setup that changes settings for your whole computer. • Check the license and the terms of use before you rebuild anything. I only studied free, open-source apps, and I built my own versions with new names. Rebuilding paid, closed software can break its terms. • These are first versions. Launching an app for real still means marketing, support and security work. • Leverage Listen uses cloud AI to transcribe and write the notes, so the audio and text leave your computer. #REA #ClaudeCode #ReverseEngineering 📣 Join Our Free Skool Community For HighLevel, Claude, n8n, AI & Automation. https://www.skool.com/automatedmarketer 🎓 GoHighLevel Masterclass + Plug-and-Play Templates.
