No separate deck to maintain — your notes are the source material.
Turns highlighted lines and note headers into question-answer pairs automatically.
An adaptive scheduler resurfaces cards right before you'd naturally forget them.
Every card links back to the note or paper it came from, in one tap.
Cards group themselves by topic tag, so review sessions stay focused.
See retention trends per deck so you know what actually needs more review.
Study sessions work fully offline and sync progress once you're back online.
Anything flagged in Euclid Notes or Euclid PDF Reader becomes card material.
Euclid Flashcards drafts question-answer pairs — edit any of them before your first review.
A short daily session keeps everything scheduled by the spaced-repetition algorithm.
See which topics are sticking and which need a deeper second pass.
