Tinder for cows - the ChatGPT app breeding a 400-cow Waikato herd

A Waikato sharemilker swiped right on ChatGPT and built Tinder for his 400 cows - the spreadsheet never stood a chance.
Key takeaway the best AI wins start with a real problem, even if that problem moos.
A Waikato sharemilker explains the app he built with ChatGPT to replace the mating spreadsheets that kept failing him - pairing cows for breeding across a 400-strong herd. The “Tinder for cows” framing is a joke; the workflow underneath is a genuinely practical bit of on-farm AI.
The “how” is the story worth telling: no software background, a real recurring problem, and a working tool built by describing it to a chatbot. For NZ agri-tech, it's a neat proof that the most valuable AI wins often start in a paddock, not a lab.
