The stack isn't anything too interesting right now, it's a pretty standard web stack. The architecture is a lot more distributed than I would prefer mostly because of the data ingestion pipeline. There's a lot more manual work that goes into this than it looks on the surface because many of the web fiction/fan fiction sites don't have proper APIs/RSS feeds. The big ones do but a significant percentage are just random WordPress sites where stuff can break at a moment's notice.

I will probably set up a Discord group for it if there's more interest, I have been getting a lot of requests for one from the user base (they don't particularly like email support, I suggested IRC or Zulip but I don't think most of them cares enough).
