I actually spent a weekend last yr doing something similar. Went through a box of old photos with my dad and wrote things down before the stories were lost. Never thought to structure it as a wiki though. Way better than the Google doc I ended up with.

The bank transaction + location cross referencing to figure out which restaurants you went to is pretty cool. Would be great if this could pull in social media exports too. Point it at your X, IG, FB archives, let it draft pages/content from that.

Any plan for a timeline view? Wiki format works well for depth but sometimes you just want to scroll through a year.
