The AI checks my Homey devices and flows and saves me a lot of handwork
He hardly touches a switch anymore, since everything that is not on a timer or presence runs by voice. Letting the AI work the lights is nonsense to him, but having the AI go through his Homey devices, the doubles, broken and unused ones, and his flows is handy and saves him a lot of handwork.
I built a morning checklist app with AI so my daughter forgets less
A mother built a morning checklist app with AI over about two weeks, running on a server at home. Her daughter checks it on a tablet each morning, and the usual items open on their own from her timetable, so she is less unsure about what to bring.

My agent found the fault on my combine that a paid mechanic missed
A farmer's John Deere combine had an electronics fault for days and a paid Deere mechanic could not find it.

They found two faulty controllers and the machine runs again.
My agent patched my home servers against a security hole and kept watch all day
A man who runs his own services at home sent his AI an article about a PHP security hole. The agent patched the services that had a fix, stopped the ones that did not, set up a watch for new fixes, and updated and restarted nearly everything as fixes landed through the day.
An LLM laid out my furniture in CAD from the boards I had
