QuestLearner AI

Type any subject and play it as an arcade run — then see the day you'll forget it, and what one replay today is really worth.

Type any subject. Play it. Find out when you'll forget it.

QuestLearner AI turns whatever you want to learn — the French Revolution, coffee brewing, Spanish past tense, quantum physics — into an arcade run you actually play. Your champion advances down a neon lane, blocks of ignorance come at you, and every one is a real question. Answer it and a light bar shatters the block.

THE FADE LINE This is the part no quiz app gives you. QuestLearner AI measures how fast YOU forget a subject from your own answer history, then draws the curve: where your recall sits today, the day it drops below your bar, and how much a replay right now is actually worth at the date you're aiming at. It goes down while you're away, because that is the honest thing for it to do.

BUILT ON PUBLISHED RESEARCH, NOT VIBES The forgetting curve, the spacing schedule and the difficulty controller all come from published work on how memory actually behaves — and the app shows you its arithmetic instead of asking you to trust a black box.

DIFFICULTY THAT HOLDS THE LINE Learning is fastest at about 85% correct — hard enough to be worth something, easy enough to keep going. The app watches your rolling accuracy and picks the next question to hold you in that band, and it tells you where you are in it.

A WRONG ANSWER COSTS YOU NOTHING No lives. No timers. No waiting nine minutes to play again. No ads, in any tier. Missing a question is how learning works, so it costs you nothing at all.

BOSS OF IGNORANCE Every quest ends in a boss made of exactly what you haven't mastered yet. It only falls to a chain of correct answers — so it tests real retrieval, not luck.

EARN YOUR CHAMPION Skins, emblems and titles come from things you actually did: a boss cleared, a quest at 80%, a chain of eight, two weeks at your target. Nothing cosmetic is for sale, in any tier.

NO DAILY STREAK TO BREAK Progress is measured in rolling weeks against a target you chose. A quiet day costs you nothing.

FREE FOREVER Playing and replaying every quest you own, boss battles, the arcade run, the difficulty controller, mastery, the weekly rhythm, the whole Champion Forge, the Fade Line for your three most at-risk quests, and 3 new AI-written quests a day.
