Tangent
A Wikipedia rabbit hole you can scroll.
The idea
Everyone has lost an evening to Wikipedia, and nobody can say afterwards how they got from one article to the next. Tangent keeps that trail. Pick something to start from and the feed keeps going — every card labelled with why it followed the one above it, whether it was linked from it, related to it, or a deliberate tangent.
Our approach
The connection is the product, so it's the thing that gets stated out loud rather than left implicit. Choosing the next article is a scoring problem: lean toward what you've shown interest in, penalize a feed that circles the same subject, and hold back a little room for surprise. That last part is front-loaded — a first session should show you what the thing is before it settles into your taste.
What it doesn't do
There's no dataset to download and nothing shipped with the app — articles come from Wikipedia live and are cached hard, so the feed stays current. It doesn't ask you to sign in either — what you like is kept in your own browser, and an account exists only to carry that between devices.
How it's built
A SvelteKit app on Cloudflare, reading the Wikipedia API through a cached proxy, with the feed engine written as pure functions and tested on its own.
