We turn your PDFs into decks worth studying
Spaced repetition is the most reliable way to retain hard material — but making good cards is slow, and most decks never get finished. GuruOwl removes that bottleneck so you spend your time reviewing, not building cards.
Upload a PDF — lecture notes, a textbook chapter, a review guide — and GuruOwl reads every page, finds the testable facts, and writes cloze-first flashcards with the source kept on each one. It’s built for serious exam prep: medicine, law, languages, and the sciences.
It is the first-draft engine, not a black box. Every card is editable before it reaches your deck, the output is a real Anki package you own, and nothing is locked behind a subscription.
What makes it different
Structured, not flat
Cards carry the mechanism and context where it helps — the depth premade decks are known for, generated from your own material instead of a generic catalog.
Image occlusion
Labeled diagrams in your PDF become masked recall cards automatically — the highest-yield card type for anatomy, pathways, and any visual subject.
Board-checked
Medical decks are audited against board standard, so a textbook oversimplification gets flagged for you to verify instead of silently shipped.
How we think about it
You stay in control
Every card is a draft you review and edit before it reaches your deck. Nothing is final until you say so.
Credits never expire
Web top-up packs do not expire and do not require a subscription. iOS subscriptions, feature access and any included-credit expiry follow the app purchase terms.
