When each card comes back.
FSRS turns your Again, Hard, Good and Easy ratings and the time since your last review into each card’s next due date.

for lasting knowledge.
Paivio is a learning engine. Several algorithms read your ratings, the structure of your notes and your exam date, and decide what you see, in what order, in what form, and when.

Inside the engineSeveral algorithms.
Several algorithms.
One study session.
What form each card takes.
Outside the research comparison, on your own decks, a card’s starting format follows how strong your memory of it is, from multiple choice up to typed recall, and no format runs more than twice in a row.
How your ideas connect.
Paivio maps the concepts in your notes and the prerequisite links between them. When the format your account is assigned uses the graph, on your own decks it orders reviews by prerequisite links within the due cards. It never adds a card or changes a due date.

A few useful answers.
Can I bring my Anki decks?
Yes. Paivio supports .apkg imports, including review history. Import your deck to continue working with your own material.
What does it cost?
Paivio is free during beta, with no credit card needed. There is no paid plan to choose during beta.
How does Paivio build on spaced repetition?
FSRS provides the scheduling foundation. Paivio adds its own concept-mapping, review-ordering and retrieval systems around the material you study.
Will every account see the same study features?
Study mechanisms depend on the fixed format assigned to the account. Review timing, ratings and due dates are the same across the comparison formats.
Can I trust every AI-generated card?
AI can make mistakes. Check generated questions and answers against your own course materials and edit them when needed.
