Alex Finn built Creator Buddy, an AI content coaching app, using Cursor without traditional coding experience and achieved $300K ARR within weeks of launch. The app analyzes Twitter content to provide personalized coaching advice. His success came from breaking down development tasks into micro-steps for AI, building in public for 6+ months, and leveraging his existing Twitter audience of hundreds of thousands of followers. The tech stack includes Windsurf/Cursor for development, Next.js, Supabase, and various AI APIs, with monthly costs around $5,300 generating 80% profit margins.

I expected clickbait, I wasn’t dissapointed.

“I have a dumb audience that I probably monetized with a crappy app that had no long-term user retention after that initial sale”
