I test whether AI gives the right answer.
I'm Mark Johnson, and Rowset is my one-person data company in metro Atlanta. I build tests that catch AI models, and code written by AI, getting things wrong. I also run CompKitchen, a flavor-pairing engine built on sourced chemistry data. Most of what's on this site links to something you can check.
