Capturing data was the main bottleneck I ran into years ago when I tried something similar with a little MS Access database. I spent lots of time making it pretty and defining fields and data types, but actually typing stuff in? I lost interest quickly.

It's possible the friction could be reduced here by having some kind of Generative AI try to help capture data, but then you'd have to verify that it was being done correctly... honestly, I think it's simply not practical for most people to do this.

Real life is messy. How much time you want to spend on recordkeeping to make it seem less messy or make you feel like you have more control is up to you. But sometimes it's better to embrace the mess and let go of control, in my opinion. Chances are, no one's going to care about whatever you do here in 100 years. YMMV as always.
