An app like Wikipedia, but fun

By the edgi team Updated October 23, 2026 Facts checked October 23, 2026

edgi is the app like Wikipedia, but fun. Every one of the 105,000 ideas on edgi's Map is matched to a Wikipedia article, and more than 44,000 of them are a 60-second Lesson you play: you guess, tap and test your way through the idea, answer a question at the end, and keep a card. Follow one idea to the next and your rabbit hole stays on a Map instead of disappearing into closed tabs. It's free on iPhone.

We make edgi, and we built it for people who love the Wikipedia rabbit hole and wish it felt like a game.

Why Wikipedia isn't fun on a phone

Wikipedia is one of the best things people have ever made. It's built to be complete, and complete is the opposite of fun on a phone screen. The article on octopuses opens with taxonomy. The good part, that most of an octopus's neurons sit in its arms, is a long scroll down, between two citations.

Fun needs three things an encyclopedia leaves out: an end, so you feel you finished something; a question, so you find out whether you got it; and a pull toward the next thing, so the rabbit hole drags you along instead of leaving you to search.

edgi has all three. A Lesson starts on the strange part, takes about a minute, and ends with a question. Then edgi asks "Where to next?" and offers a few connected ideas, each marked with why it's there (Zoom in, Bigger picture, Something different), plus Surprise me for a random one. The idea you finished becomes a card, and the card lights up on your Map next to the ideas it connects to.

Wikipedia app features from Wikimedia's release notes and June 2026 coverage; Wiki Rabbit and The Wiki Game from their App Store listings, checked October 2026.

Every road used to lead to Philosophy

Wikipedia has a famous game hidden in it. Click the first link in an article, then the first link in that one, and keep going. In February 2016, 97% of English Wikipedia articles ended up at Philosophy that way. Then editors kept changing opening links, and after a round of changes in July 2026 Wikipedia's own page on the game says almost no articles lead there anymore.

edgi's Map has its own center of gravity. We measured it: of the 400 most-connected ideas, the one the rest reach fastest is Thermodynamics, 5.4 steps away on average. Any two ideas are typically seven steps apart, and Dinosaur gets to Black hole in four. The routes are on our rabbit-holes page.

Here's the Lesson on where every road used to end:

Philosophy Philosophy is a loop: take a stand, find the case that breaks it, and build a better rule.

A rabbit hole that adds up

Two hours on Wikipedia ends in twenty open tabs. An hour on edgi can end in twenty cards, each on your Map beside what it connects to, and the trail is still there tomorrow. Cards turn foil and then gold as you come back to an idea. Sets give a rabbit hole a finish line: How Gothic Cathedrals Got Their Windows is seven cards, and so is Why the Sky Is Empty of Aliens. One Lesson a day keeps your streak.

When a Lesson raises a question edgi hasn't covered, type it in and make your own Lesson on it, or a quiz, or a longer Explainer you can listen to.
