In this video, we set up REA (Reverse Engineer Anything), the open-source tool that went viral on GitHub. We connect it to Claude Code for free using 9Router, and then try to rebuild a full office suite (documents, spreadsheets, slides and paint) from just one prompt.

━━━━━━━━━━━━━━━━━━━━
⚠️ USE RESPONSIBLY
━━━━━━━━━━━━━━━━━━━━
Only inspect software you own or are allowed to analyze, and follow each app's license and terms of service. REA helps your AI understand how a feature works so it can write its own original version. It does not give you the app's source code. Never copy someone else's code, branding or paid content.

Free AI model limits change often, so check each provider for current limits.

Not affiliated with or endorsed by Microsoft, Anthropic, or the creators of REA or 9Router.
