You learned it.
Then your brain
quietly deleted it.
knojo turns your notes into a daily five-minute review queue and brings each idea back the moment before it fades. Show up for a few focused minutes. Actually keep what you learn.
Question
What does the spacing effect say about memory?
Answer
We remember more when reviews are spread out over time than when they're crammed together.
Your memory has a leak. We patch it on schedule.
Without review, you lose roughly half of what you learn within a day. Each time knojo resurfaces a card right as it's about to slip, the memory resets stronger and the next gap gets longer.
That's spaced repetition — and it's the whole game.
Three moves. Then let the queue do the thinking.
Feed it anything
Paste notes, an article excerpt, or a lesson recap. knojo's AI turns raw text into clean question-and-answer cards in seconds — or write your own.
Review what's due
Each morning knojo hands you only the cards about to fade — usually a five-minute stack. Not your whole deck. Just the ones that need you today.
Rate it, forget the scheduling
Tap Forgot, Hard, Good, or Easy. knojo picks the exact day to bring each card back so it lands right before you'd lose it. You never plan a thing.
Everything you need to make it stick.
AI card generation
Messy notes in, review-ready cards out. Turn a lecture or an article into a deck without typing a single question.
Learning goals
Run the biology final, React interview prep, and Dutch vocab side by side. Every goal keeps its own queue.
AI quiz mode
Turn today's material into a tricky multiple-choice check while it's fresh — then see exactly which concepts you missed.
Streaks & belts
Daily streaks, 100-day milestones, and a wall of achievements that reward showing up — not cramming.
Smart reminders
One daily nudge, timed to when cards are actually due, hard, or about to slip. No spam.
Your daily memory coach
A plain-language read every morning on what's due, what's hard, and what's about to slip — so you always know the smallest next step.
