The Sanderson wiki [1] has a time-travel feature where you read a snapshot just before a publication of a book, ensuring no spoilers.
I would like a similar pre-LLM Wikipedia snapshot. Sometimes I would prefer potentially stale or incomplete info rather than have to wade through slop.
But you can already view the past version of any page on Wikipedia. Go to the page you want to read, click "View history" and select any revision before 2023.
Have you personally encountered slop there? I tend to use Wikipedia rabbit holes as a pastime and haven’t really felt a difference.
The easiest way to get this is probably Kiwix. You can download a ~100GB file containing all of English Wikipedia as of a particular date, then browse it locally offline.
I'm not sure if it's real or not, but the Internet Archive has a listing claiming to be the dump from May 2022: https://archive.org/details/wikipedia_en_all_maxi_2022-05
