Memory is not
permanent by default.

Newly learned information begins fading within hours unless it is revisited at precisely the right moments. A century of cognitive science has documented exactly how and when this happens. Almost none of it has reached the classrooms where it could make the most difference. That gap is what this work is about.

The Core Problem

Students don't forget because they're not trying.

Over a century ago, Hermann Ebbinghaus demonstrated what is now called the Forgetting Curve: without deliberate reinforcement, most newly learned information disappears within days. This is not new knowledge. What is surprising is how little it has changed classrooms.

In most learning environments, especially those with limited resources, the structure remains unchanged: information is delivered, briefly practiced, tested, and then forgotten. The system assumes learning has happened, but memory rarely agrees.

Cognivia began with a single question: what if we designed learning around how memory actually consolidates, not around how teaching is conveniently organised?

What the science settled

Three findings the field settled decades ago, and almost no classroom acts on.

Every feature in Cognivia maps directly to one of these mechanisms in the cognitive-science literature, nothing else.

01

Spaced Practice

Distributing practice over increasing intervals exploits the spacing effect. Each successful retrieval strengthens the memory trace and extends the optimal review window. Cognivia implements the full adaptive review algorithm: a personalised ease factor and interval per card per student, updated after every response using a 1–5 quality rating. Struggling items return the next day; mastered items in weeks.

The review algorithm ease factor adjusts continuously per student per card, creating a schedule that is individualized, not uniform.

02

Active Recall

Forcing reconstruction of an answer from memory, rather than passive re-exposure, produces substantially deeper encoding. Roediger and Karpicke (2006) found retrieval practice outperformed re-study by ~50% on one-week delayed tests, even when re-study groups spent more total time. The generation effort is the encoding event.

Every Cognivia session is structured retrieval. The correct answer is revealed only after the student attempts a response. No passive exposure mode exists.

03

Desirable Difficulty

There is a well-documented gap between what feels like effective studying and what actually produces lasting memory. Re-reading notes feels productive because the material looks familiar. But familiarity is not the same as genuine recall. The methods that feel harder in the moment, trying to remember without looking, testing yourself before you feel ready, reviewing material that has already started to slip away, consistently produce better long-term retention because of that difficulty, not in spite of it.
