What to check before you trust Anki flashcards

Are Anki flashcards safe? For most people studying alone with their own cards, the risk is low. The main questions are whether a shared deck contains wrong or unwanted content, and whether an add-on you install can run code on your computer.

  • Check who made a shared deck and read several cards before you rely on it.
  • Install Anki add-ons only from sources you trust, since they can run code.
  • Review exported files before you share them with classmates.
  • Making your own cards from your notes keeps the content under your control.
