Xikipedia is a website that presents Wikipedia content as a doomscrollable social media feed, using a non-ML algorithm to suggest similar content based on user engagement. The algorithm runs locally on the user's device, and no data is sent to the server. The website requires a 40MB download to function, which has led to loading issues for some users. The creator of the website aims to demonstrate how a basic algorithm can learn user preferences without relying on machine learning or user data.
