One idea per card.

A moment, a number, a reveal, a quiz. Twelve real cards from the library; there are 4,606 where they came from.

    A teenage agreement that outlived the band

    Lennon and McCartney agreed as teenagers to credit every song to both of them, whoever wrote it.

  • Guess first · Basketball

    2.5Mmen landed through one artificial harbor

  • Guess first · The iPhone

    What is the difference between a priori and a posteriori?

  • Taylor Swift · What people still argue about

    Most arguments about her end at a public record

    Critics say album variants inflate her charts. Billboard counts every copy, and K-pop did it first.

  • By the numbers · The Roman Empire

    8 yearsto build the Colosseum

    100 daysof games to open it

  • Guess first · Money

    What stops banks creating money forever?

    RevealedReserves do not run out, so no vault limits them. What stops them is price, risk and rules. Every loan is a bet that has to be priced above its expected losses.

The bar test

Every chapter has to pass it. Here is what passing sounds like.

A stranger

The internet is dead. It was better back in the old days.

You, one chapter later

Because every wave of newcomers looks like the end to the people already there. In September 1993 AOL connected its users to Usenet, the discussion boards, and the old hands called it Eternal September.

From The internet “How to talk about it”

After one chapter, you can say something true, specific and slightly surprising to a stranger. That is the whole product.

+0 XP on a chapter you already cleared. Replays are free; they are not progress.

Five minutes, not five hours.

  • One idea per card

    A moment, a number, a photograph, a reveal. Never a wall of text you scroll past.

  • Wrong answers are real traps

    The pleasure of a good quiz is nearly falling for option B. Nobody writes option C as a joke.

  • A streak that doesn’t lie

    XP is a ledger, not a counter. Replay what you’ve cleared and it honestly reads +0.

What we collect

Versed measures how the app is used, and says so here. Which screens and chapters you open, how your quizzes go and whether a purchase went through are reported to PostHog; crashes are reported to Firebase Crashlytics. No ads, nothing sold, no tracking across other apps. The reports are on by default, and Settings › Account turns them off. You can read without an account.
