How it works
Every subject is a trail of chapters, and every chapter is a run of cards. Here is a real one, from Basketball, card by card.
Basketball · Where the game is now
Moment
17 January 2003
Yao Ming, a 7-foot-6 center from Shanghai, meets Shaquille O’Neal, the Lakers’ center, on court for the first time. A reported 200 million people watch in China. Yao, the first pick of the 2002 draft, turns the NBA into a Chinese broadcast staple.

Most chapters open on a date and a scene, written the way someone who was there would tell it at a bar. Specific beats general: a year, a street, a number of people in a room.

Numbers are ammunition. Three figures, each with the one-line context that makes it worth saying out loud, instead of a paragraph that buries them.

Guess first
Why did the league impose a 65-game rule?
RevealedBecause broadcasters were paying for stars who were sitting out nationally televised games while healthy. It is a television problem solved with an awards rule.
3 of 4 · Guess first
Guess first, then tap. The question is one people actually ask, and the answer lands a fact worth repeating rather than restating the obvious.

Quick check
How many games must a player appear in for award eligibility?
Nailed it. Introduced in 2023 to counter load management. Joel Embiid, the reigning MVP, missed the cut in its first season.

The wrong answers are written to be plausible. Get it right and Vee cheers; get it wrong and the explanation hands you a bonus fact instead of a scolding.
There is one canonical spine, from why it matters to how to talk about it. World War II has 13 chapters; Crypto has 9. That asymmetry is honest, and the app says so out loud.
XP is a ledger, not a counter: replay a chapter you have already cleared and it honestly reads +0 XP. Quiz answers are first-answer-wins. Completion counts once.
The daily goal has four tiers, counted in cards. The top one is a real commitment.
A name or a term you don’t recognise is usually a link. Tap it and a sheet opens with just enough to keep reading, plus every other chapter that mentions it. The reader who came for Formula 1 leaves wanting the 2008 crash next.
Moment · 1 August 2024
The first comprehensive AI law anywhere, in force across the European Union from 1 August 2024. It sorts uses by risk. The worst-rated uses are banned, high-risk ones carry duties, and the rules phase in over several years.
