You memorize answers, not concepts. You see duplicates for years. Difficulty labels are meaningless. And when the exam format changes, your prep doesn't.
AI generates questions in real-time. A 4-stage quality pipeline catches duplicates, validates difficulty, fixes formatting, and reviews diagrams before anything reaches you.



ARENA MODE — TIMED ROUNDS WITH LIVES, DIFFICULTY LEVELS, AND COMBO SCORING
Every question passes deduplication, difficulty scoring, markdown validation, and diagram checks before reaching you.
The same algorithm behind Anki. Easy, Got It, Hard, Don't Know — each rating schedules your next review.
100+ exams with dedicated quiz pages. USMLE vignettes. FMAA chapters. LSAT logic games. Each exam, its own format.
Questions get harder as you improve. The difficulty label is validated by AI scoring against exam-specific rubrics.
Gamified rounds with lives, combos, and a deck that never runs out. Mastered cards are replaced by fresh AI-generated ones.
A draggable AI assistant available on every page. Ask questions mid-quiz. Context-aware, theme-aware, always there.




Every answer comes with a step-by-step breakdown — why the right answer is right, why the distractors are wrong, a mnemonic you'll actually remember, and a real-world case.
When anatomy or a process matters, Hikari draws you a validated diagram. No more flipping to a textbook.


The Exam Readiness Score combines your coverage, accuracy, and recency into one number. No guessing. No surprises on exam day.




30 days free. Charged only after day 30. Cancel anytime.
