Texts worth keeping

People have always carried texts in memory — poems, prayers, speeches, lines for a play, the periodic table before an exam. What they haven't had is software that treats a continuous text with the same care flashcard apps give isolated facts.

ByHeart schedules every line of your text with modern spaced repetition (FSRS), and adapts how much of each line is hidden as your memory strengthens — from first-letter cues to a fully blank page. The highlighter lifts; the words stay.

We're a small team that cares about typography, latency, and the feeling of finally reciting something whole. Your library is private by default, exportable always.
