Issue #9: 6 AI money cases, 4 payment-verified, grown through ads, SEO and YouTube creators

6 cases this issue. 4 come with payment-platform data on TrustMRR (rechecked 2026-10-21): Brawler, an AI boxing coach app, at $22,550 MRR; QR Code AI, AI art QR codes, at $14,827 MRR; Fiddl.art, several image and video models on one site sold via points, at $13,336 in the last 30 days (a window metric, not monthly revenue); and OpenTweet, an X scheduler a DevOps engineer first built for himself, at $4,006 MRR. The other 2 amounts are self-reported, unverified: the founder of Dropmagic, an AI store builder, says $120K MRR, and the maker of CountryTaxCalc, a multi-country tax calculator site built with AI by someone who couldn't code a year earlier, says about $1,000 a month in ad revenue. Each grew differently: Brawler through Meta ads and influencers, QR Code AI, Fiddl.art and CountryTaxCalc through search traffic, OpenTweet through the founder growing his own X account with it, and Dropmagic through YouTube creator partnerships.

Tool pick

Claude Code

Strong at long tasks and repo-wide refactors; the most frequently mentioned tool in our cases.

Takeaway

None of the 6 products is complicated; the difference is where the money comes from. Some pay for users with ads, some wait for Google to index them, some start as their own first user. QR Code AI and CountryTaxCalc both grabbed one search term first and built pages around it; Fiddl.art worked out the cost of each generation before pricing its points. Pick a channel you can keep feeding before you build.
