Memorisers who make their own cards get a free spaced-repetition tool, except the iPhone app at £24.99, and it is not really AI.

Kenning's take

What it does

A free, open-source flashcard program that uses spaced repetition: after each card the learner rates how well they remembered it, and Anki schedules the next review for just before it would be forgotten. Cards can hold text, audio, images and video, and a free AnkiWeb account syncs decks across computer and phone.

  • spaced repetition scheduling (SM2 and FSRS)
  • free AnkiWeb sync across devices
  • audio, images, video and scientific markup on cards
  • shared decks made by other users
  • add-ons to extend features
  • handles decks of 100,000+ cards

Who it suits. Students and self-learners who want to memorise large amounts of material and are happy to make or import their own cards.
