A new dad on paternity leave built a full baby tracker with AI in a week, then opened it to other parents as a cheaper SaaS after finding existing trackers obscenely priced. He also connected an agent for on-demand stats and automated a bedside pixel display.
He let his daughter chat out loud with AI to make a game, and the AI gave her small kid sized coding lessons along the way. They put the game on his Raspberry Pi box with an Arduino joystick, so she can play it whenever she wants.
A fellow parent pointed him to the Tilt Parenting podcast, which has more than 500 episodes. He told his second brain in an AI app to search the archive for episodes relevant to his situation, and it picked 29 episodes, saved their transcripts, and wrote him a brief on what each one could teach him.
School news for his two kids comes through six Facebook groups as well as email. The AI watches all of them, asks him which events he wants to track, spots clashes like a field trip on the same day as a dentist appointment, and keeps his calendar updated, and it also pulls the Scouts dates together and, before a camping weekend at two different spots, told him the weather at each one and what the boys should pack to stay warm.
Used LLMs to build several apps and sites for his family and kids in evenings instead of months, including a shared drawing canvas his kids love.
His son is into Rubik’s cube competitions. Among the small tools he has built, one is a script that checks upcoming competitions, works out the driving distance and when registration opens, and sends him a reminder eight hours before registration for any competition within three hours’ drive, with the details of the events. He does not say yet whether it has caught one.
The AI whipped up an animated demo to teach his 5 year old why the sky is not black, a better explanation than existing ones he found.
He built an app that lets their nanny track her worked hours in it, so the family does not have to keep track so closely. The app holds their contract details with her, including the exceptions for vacation and sick days, and gives a total at the end of the week for payment reconciliation. It is one of several small apps he has built for family life.
After reading the AI’s summary of an embargoed PR pitch, Ulanoff had it draft a reply. The first draft overpromised a meeting, so he had it strip the meeting references to just agreeing to the embargo and getting images and details.
