I made an app for myself and the local MTB community for keeping track of rain and soil moisture for nearby trails so it's easier to decide when a trail will likely be open. Much more reliable than waiting for the official (volunteer led) organization to update the status. I never would have made it without an LLM to speed things along.

A good friend of mine helped his mom keep track of Meals On Wheels (or a similar volunteer org) orders, deliveries, cancellations, etc. They were managing all of this via paper before.

I compiled a list of online recipes. Then I had an LLM typeset them for me into a printable PDF and build a companion website with links to the original recipes and complete ingredient lists for shipping. had the LLM encode links for the companion site into QR codes so the printed copy of the cookbook would bring me immediately to a shopping list, making trying a new recipe soooo much less daunting.

There are so many little things like this that you can make that just take too much effort to justify otherwise. I have other ideas for personal projects that I'll probably get to some day.
