Knowledge Factory

Knowledge Factory borrows the idle-game design behind Cookie Clicker and AdVenture Capitalist and points it at studying. Every question you answer correctly earns Knowledge Points. KP buys upgrades. Upgrades raise how many KP each correct answer earns. You watch the earnings curve climb the way you would in any tycoon game, except the work driving the curve is reviewing your material.

Streak multipliers are the heart of how it feels. Answer several in a row correctly and your KP-per-answer rate compounds, which rewards staying accurate instead of guessing your way through the deck. Miss one and the streak resets. Losing a 20-question streak genuinely stings, and that small artificial stake is what makes the review feel like it matters. The setup rewards consistency over speed, which is also what the research recommends.

Upgrades come in tiers and play off each other. Some boost base KP, some raise the streak multiplier ceiling, some smooth the difficulty curve on harder questions. The optimization is fun if you're the kind of student who likes a spreadsheet-y game, and the time you spend planning the next upgrade is time you're not spending procrastinating on the material. A useful trade.

Progress saves automatically, so Knowledge Factory works as a tool you come back to across sessions. The factory grows over days the way a real idle game does, except that growth depends on you showing up and answering questions. That long-tail progression is rare among study tools, and it's a big part of why the students who like it keep coming back.
