Boss Battle

Boss Battle is an RPG-style duel where the only way to deal damage is to answer questions from your own study notes. Upload a PDF, DOCX, image, or paste text. The AI pulls out the key concepts and turns them into multiple-choice questions. A correct answer attacks the boss in front of you. A wrong answer chips away at your own health bar. Having HP on the line gives review some real stakes, and that tends to help things stick.

Bosses are themed and get harder as you go. You start against simpler opponents, then work up to stylized characters like The Architect, The Destroyer, and Quantum Sage. Each one has its own art, attack pattern, and difficulty, so a long study session doesn't blur into one repetitive screen. Hint potions let you peek at the answer when you're stuck. They help on a first pass through new material, less so when you're trying to lock in recall before an exam (which is the point).

The mechanics here are active recall and immediate feedback, the two things cognitive science backs most strongly for long-term retention. The XP layer on top is borrowed from RPG progression, mostly so the loop feels rewarding instead of like a chore. You spend the same time on review, but it's easier to start and easier to stay with.

Adaptive difficulty nudges the challenge up or down based on how you're doing, so the boss stays beatable without turning into a pushover. That keeps you in the productive middle zone, between bored and overwhelmed, longer than a plain quiz screen usually manages.
