Adaptive spaced repetition

Learning evolved for lasting knowledge

Paivio builds a knowledge graph of what you know, then puts the right card in front of you on the day you were about to forget it.

How it works

It learns how you learn.

01

A graph, not a deck

Concepts connect. When you finally understand preload, everything downstream of it is rescheduled too, because the graph knows what depended on it.

02

The format is a decision

Recognition is not recall. Paivio chooses cloze, free recall, or a diagram based on how you have failed that concept before.

03

Timed to the edge of forgetting

Reviewing too early wastes the session. Too late and you relearn from scratch. The schedule aims at the moment retrieval is still just possible.

Early access

Join the waitlist before your next exam block

We are onboarding college and pre-med students in small groups so the scheduler gets real feedback. Pro is $9 a month after beta, and early members keep that rate.
