## What is DeckShift?

Turn any PDF, lecture, or note into a deck in about 30 seconds. DeckShift uses FSRS spaced repetition to schedule only the cards due today, and shows you the forgetting curve so you study what you are about to forget. Make cards, review, remember.

MAKE
Paste text or import a PDF and DeckShift drafts clean question-and-answer cards for you. Edit anything before you save it to a deck.

REVIEW
Each session surfaces only the cards due today. Rate how well you recalled each one and FSRS reschedules it for the moment you are most likely to forget.

REMEMBER
Watch the forgetting curve for every deck. See what is fading, what is solid, and where to spend your next ten minutes.

IMPORT
Bring your existing Anki and Quizlet decks with you. Your cards, your schedule, one place.

TRACK
Daily streaks and per-deck progress keep the habit going without turning study into a chore.

Free to start. Sign in with Apple, build your first deck, and review whenever you have a few minutes.
