https://hydrusnetwork.github.io/hydrus/ Are you familiar with Danbooru, if so it's a local version of that. If not, it's like using Ao3 tags but for describing art. It's kinda complicated to set up at first, and it's probably overkill if you have a small collection, but it can do things like download art automatically from your favorite artists, and you can search your art based off of not just who's in them but what they're doing. Here's a picture straight from the official page to show what it looks like. I'm pretty shit at explaining, sorry.
