@openai: Someone claiming to be her grandson told her he was in trouble, and that he needed $5000 immediately. She rushed to the bank to wire the money. Then, at the last second, a bank teller stopped her—they realized she was getting scammed. @BetterWithAI, who’s worked in banking technology for decades, had already seen how pervasive scamming older folks had become. So he decided to take matters into his own hands and make an app to help them avoid the traps. The problem was he didn’t know how to code. So he asked ChatGPT to teach him how to build an app from scratch. ChatGPT interviewed him about his idea, and helped turn it into a detailed requirements document for a vibe-coding tool. ChatGPT also advised him on accessibility for elderly users, inspiring him to make the app black-and-white with big buttons for easy reading. After a week of tweaks with the coding tool, Matt had successfully created Scam Skeptic, a free app that teaches people to recognize common scams through bite-sized lessons and recurring quizzes. Scam Skeptic currently has thousands of users, including Matt’s parents. Matt says they now like to talk to him about fresh scams they’ve recognized and avoided, sounding like truly proud (and skeptical) parents. For more info on Scam Skeptic, go to www.scamskeptic.com
