How it works
Cards on a schedule, not a stack
Add the material
Upload a lecture PDF, paste notes, or use a guide Sparky already wrote. The cards come from your set.
Sparky writes the cards
Terms, cloze, and the other formats you drill. Missed cards return soon. Known cards wait.
Rate each card
Mark what still slips. The next session is the hard ones, not the whole packet.
See the cards again when they fade
Missed cards come back first
Rate a card after you flip it. The ones that slip return sooner than the ones you already know.
Open FlashcardsThe card types you actually use
Classic, cloze, and more. Pick the mix that matches how you study.

Mastery by topic, so you spend the next session on the weak parts of the deck.
Open FlashcardsStart from the notes, not a blank deck
Typed notes, a PDF, or the guide Sparky wrote from lecture. The cards read that file.
Open AI NotesNotes
Same cards. Different ways in.
Build the deck from a PDF, from notes, or follow the Leitner loop.
Start from somewhere else
A file conversion, a named method, or a subject how-to.
Spaced repetition questions
You add your lecture or notes to StudyFetch. Sparky writes flashcards, then shows a missed card again soon and a known card later, so you stop rereading material you already know.
After you flip a card, you rate how well you knew it. Cards you miss come back in the next sessions. Cards you know wait longer.
Your material. Upload a PDF, paste notes, or use notes Sparky already wrote. The deck is built from that set, not a generic pack.
Leitner is the named method: boxes and a review loop. This page is the app that writes the cards from your files and runs that schedule.
You can start for free. Sign up, add a lecture or notes, and generate your first deck without paying up front.
