Margin Cues
Turn raw lecture, reading or meeting notes into a cue-column study page, then cover the notes and test yourself. Free in the browser: the notes split into parts, definitions and the spots you marked unclear found, a draft cue per part on a ruled page, a covered-notes self-test and Markdown/CSV/print exports. Two metered runs: rebuild the page (cue questions beside condensed notes, a summary, key terms and gaps - ready / patchy / thin, using only your notes) and check the answers you wrote from memory (solid / partial / gap / wrong per cue on a report card). Built on @szeyu/study-notes-creator and @neurofoo/feynman.
