Everyone's covering REA, the repo that lets Claude reverse engineer any app. I wanted to answer a different question: what have you actually cancelled? In this one I show the board of what I killed (Slack, Notion, Flex, Adriel and HypeAuditor, more than $2,000 a month) and the one app our team uses in their place. HypeAuditor alone was $1,500 a month, and it turned out to be a scraper with a dashboard. I also show where REA really earns its place: I pointed it at Ableton 12, and it told me why one person isn't cloning it. Plus the rule I use to decide what to rebuild and what to keep paying for, and the open-source Premiere I'm testing. The prompts I used are in the video description. Drop one app you're paying for below, and I'll tell you if I'd rebuild it or keep it.
