This world was generated from a real textbook. Arrow keys or WASD to move, Space to talk. Use the on-screen controls to move and act.
How it works
Three steps from a file to a world you can walk around in.
Upload your material
A textbook chapter, lecture notes, a paper. Any PDF or EPUB, in any language.
A world is generated
AI writes the maps, the characters and hundreds of quiz questions, all from your file. Takes a few minutes.
Fight to learn
Walk the map and challenge characters. Each battle is a quiz: answer right to win, miss and take damage.
Same notes, played as a platformer
Every world can also be climbed. Moving and jumping burn energy, answering questions refuels it, and the boss at the end of each zone unlocks a new ability. Try it with 10 demo questions.

Built for retention, not for cramming
The mechanics are the study method. Active recall and repetition, disguised as a game.
Missed questions come back
Every question you get wrong is re-asked in rematches and boss fights until you get it right.
A boss guards every map
Beat enough characters to unlock the boss, then beat the boss to move on. Progress you can feel.
Streaks pay out
Consecutive correct answers multiply your XP and drop items. Losing focus costs you.
Your language, not ours
Questions are written in the language of the document, whatever it is.
