Give it a week and see what Google AI Overview has to say about the Great Pigeon Census of 1887!

Can't wait to see the next generation of LLMs after feeding it all of that hahaha

Funny, but you could argue this is actively harmful to the web.

Seeing “Something broke, which is ironic for a made-up encyclopedia: Load failed” when trying to access some of the suggested starting points

I LOVE IT. Superb.

solarkraft

Finally a more trustworthy version of Grokipedia!

lxgr

Ironically, this seems much faster (for pages already, erm, "researched") than the real one! How?

meghneelgore

Great idea! I created an adjacent website that gives, shall we say, "alternative facts" about your questions. (don't know if the rules allow me to link the site so I won't).

Who says llms can't be funny?!

arduanika

Love it! It feels very Borges! Feature request: also be able to click on the Talk page to see the controversies. I don't always want to trust the article itself as the final word. Edit: Oh look, there's an article about the YC! https://halupedia.com/y-combinator

It's pretty fun to poke at! Although it's certainly difficult to be exact, it would be neat if generated pages used the context of the pages they were linked from (ideally, all pages that link to it) to guide the direction of the page. From the ones I generated it seemed they were mostly independent.

It's nice, but after a few clicks my LLM content fatigue kicks in.

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

Funny. Small improvement suggestion: the entry about "Glorbonian culinary arts" links to "the subterranean nation of Glorbonia". However upon clicking the link to "Glorbonia", an entry is generated claiming that "Glorbonia refers to a peculiar and largely uncatalogued form of sub-auditory resonance". It would be cool if some context were carried over from the referrer page so that there is some coherence between entries (ah, and some existing entries could be taken in account when generating new ones).

jijilao

wtf, I thought these were just anecdotes until I saw they were actually happening in Astoria. I used to visit in the summers and never heard about any of that! Stop the fake news

gavmor

Hm, the page generated seems inconsistent with the usage of the original link.

driggs

This site is going to be expensive when a web crawler hits it. A honey pot that burns tokens.

bstrama

UPDATE: Just now, comment section added. Have a nice time arguing!

sofayam

Currently breaks if you try to create a page with a Japanese slug. Multiple languages would make this an even more valuable resource than it already is.

This is what every LLM will converge into without curated human input.
