What it does

Users create cards to store notes, language vocabulary, concepts, reading highlights, or passing ideas. 氢刻 then organizes these cards into a Personal knowledge base.

A review system recommends what to study based on your progress, drawing on the Ebbinghaus forgetting curve to space repetitions.
