This is fantastic. I couldn't find any obvious way to search for a new page, but you can simply bang out any arbitrary URL slug and the new article will be hallucinated fresh, eg:

https://halupedia.com/shortest-cave-in-the-world

https://halupedia.com/echolocation-ability-in-spiders

Hit the Stumble link at the top right of all pages - its as good as a search when the whole thing is made up!

Exactly, but I consider adding fake search that could find you ANY article, including not existent ones

This is excellent, congrats!

FYI I manually created this page and some link markup looks malformed: https://halupedia.com/list-of-uninhabited-countries

Looks like some single quote escaping issue? I suspect the first link to be "Archduke Ferdinand VII's Bureau of Non-Demographic Surveys" and the apostrophe breaks the link.

All articles exist, some just haven't been discovered yet ;)

Yes, that would be the perfect touch. This is brilliant satire. We need more satire!
