Ask HN: How do you remember what you've learned? I've been using google keep to take notes and remind myself to review them with spaced repetition (more about spaced repetition https://apps.ankiweb.net/docs/manual.html) Nice things about using keep for this: - access from any device - nice UI - supports images - reminders to review a note - half decent text editor - searchable - categories - free cons: - mixed in with other notes in the default view - hard to export for review in other formats - have to manually set the interval (e.g. using reminder tool to set 3 days from now, then 1 week, then 1 month ect). This is tedious - not suited for larger documents - not really suited for flashcard style of studying Other things I've tried: - folders with text files - ankiweb |
