Dozens of them. The most useful in the house are the grocery list and the status-panel iPad. I wanted those tools but was always too busy, AI turned them both into one-evening projects. They are done and good-enough faster than I could evaluate the existing market offerings.

And some tools for my investing maths.

I built a few Python scripts for my blog - one that builds a links page and adds metadata for the links, and one that adds metadata to youtube embeds. I'm working on a booklist script and a game script that link to the Open Library API and itch.io api respectively. I've started playing with tkinter layouts for these but I honestly still find just using shell scripts easier.

And I'm not using AI for any of it. I know it's implied in your question that anyone answering would be, and it's sad that I have to make that qualifier because HN is so AI pilled.
