Blessfrey.me uses LazyWiki, personal wiki software with lazy linking. All wiki links are automatically generated, meaing this wiki is so lazy, it doesn't insert the links until that exact moment you are loading the page. This takes some processing power, but it enables a single person to maintain a wiki while worrying only about article writing, not the links.
It's pretty slow! Maybe EagerWiki wouldn't be so bad. It would be slower for me to use, but you could load new articles more quickly.
It only matches partial words right now, but eventually, it will only match full words and synonyms.
Originally developed by my husband in Bottlepy for me while we were dating. :) I've used it consistently in some form since 2017-ish and hosted it online since 2023-ish.
