Engram schedules what you study with a state-of-the-art model of memory — difficulty, stability and retrievability. And unlike every other app, it shows you the model: the exact chance you'd recall each card, right now.
People pour hours into revision and keep almost none of it — because the methods we reach for by default are the ones cognitive science has shown barely work, and the tools that do work hide the one thing that matters: how likely you are to remember.
Highlighting and re-reading give a feeling of fluency, but little durable memory. The effort that builds memory is recall, not review.
New material can lose half its strength within days without reinforcement — the forgetting curve. Massed study fights that curve instead of using it.
Even the best tools never show you why a card is due, or how firmly you hold it. Engram puts the memory model on the surface.
Engram's scheduler is built on the DSR model — difficulty, stability and retrievability — the approach behind FSRS, the current state of the art in spaced repetition. For every card it predicts your chance of recall right now, and times the next review for the exact moment that chance falls to your chosen target. You set the target; you see the model.
Add cards by hand, paste a whole set at once — or let the built-in AI draft recall cards from your notes.
A short daily session. You retrieve each answer from memory before you see it — the act that actually builds it.
Each rating updates the card's stability and difficulty, and sets the next review from your target retention.
Your dashboard shows retention holding high instead of decaying — the science, in your own data.
Memory lasts longer when study is spread over time instead of crammed. Engram sets each card's next review for the moment just before you would forget it.
See the library →Actively recalling something strengthens the memory far more than re-reading it. Every card is a recall test, never a re-read.
See the library →Memory decays predictably after learning. The DSR model fits a curve to each card, so stability — how slowly it fades — grows with every success.
See the library →Built honestly, in order — each step turns the prototype into something more people can rely on.
Difficulty, stability and retrievability — the model behind FSRS — running live, and made visible on every card.
Paste your notes or a topic and Engram drafts the recall cards for you — removing the biggest point of friction.
Your decks on every device, backed up, so study follows you from laptop to phone — the login that will gate the app.
Fit the memory model to your own review history, so the timing gets more accurate the more you use it.
