First off, this is a super cool project. Kudos to getting it started and up and running. Family history, and memorabilia and organizing all that stuff is super challenging, and just having a proper site to look at is worth its own effort.
Unlike some of the comments herein, I find this as a perfect use of technology in service of users. (Yes, with some limits). I liken this to Maggie Appleton's Home-cooked Software model [1], wherein barefoot developers use technology (AI-driven or not) for writing apps for their own purposes, nominally for a user base of 1 (or very few), with possibilities of expanding to a few dozen.
In that vein, I'm a barefoot developer, and much of the software I have written in the past few months (with help from Claude, ChatGPT) is very much for that tiny user base of a few dozen (=mostly me, if I'm honest). And that is perfectly fine by moi.
I wrote a utility to organize roughly 100K+ photographs (and videos) neatly into dates/location, both for backup, as well as to maintain the memories in an organized fashion. Asked Claude to lookup location by EXIF; haven't yet asked it to "guess the location by photo" when no GPS info existed in the EXIFs. But I think I might do that.
(no, I haven't asked Claude to go thru my Uber trips or bank statements! I draw a line there!)
That is why the OP's personal wiki made me so excited - because the whole output resonates with me.
Like a few commenters mentioned their journaling experiences. I've started doing that with some of our trips (mostly post pandemic), both to remember our experiences better, and to come back to them as needed. The simple act of writing down places visited, experiences had (mostly hikes, mountains climbed, meals consumed in distant foreign places, weird/quirky experiences) causes them to be fresh in one's memories.
Thanks, this was a great project, and a great reminder as well.
