From Messy Notes to Flashcards, Automatically: How knojo Works
TL;DR
knojo is a spaced-repetition learning app that turns your notes into flashcards automatically. Paste notes or an article, and its AI writes clean question-and-answer cards in seconds. Each morning knojo hands you a five-minute stack of only the cards about to fade, then reschedules each one based on how well you knew it — so you remember what you learn without planning a thing.
knojo is a spaced-repetition app that turns your notes into flashcards automatically and schedules them so you actually remember what you learn. Instead of writing cards by hand and guessing when to review, you paste in raw notes, knojo's AI turns them into question-and-answer cards, and a spaced-repetition engine decides when each card comes back.
The problem it solves is the one every learner knows: you understand something today and it's gone next week. That's the forgetting curve at work — without review, we lose roughly half of new material within a day. knojo closes that gap with a five-minute daily habit.
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.
How knojo works, step by step
- 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 you can 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.
- 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.
The core idea
You bring the raw material and a few minutes a day. knojo handles the card-writing and the scheduling — the two chores that make people quit flashcards.
What makes knojo different
Most study tools make you choose between writing every card by hand (accurate but slow) or generic decks (fast but not yours). knojo's AI card generation gives you cards from your own material without the typing, and the spaced-repetition scheduler means you never plan a review session.
| Manual flashcards | knojo | |
|---|---|---|
| Creating cards | Type every question and answer | AI turns your notes into cards |
| Scheduling reviews | You decide when to study | Automatic spaced repetition |
| Daily session | Your whole deck, or you guess | Only what's due — about 5 minutes |
| Multiple subjects | Separate decks to juggle | Parallel goals, each with its own queue |
| Staying consistent | Willpower | Streaks, milestones, and one smart reminder |
Run several goals at once
Learning goals keep each subject in its own queue. You can run a biology final, React interview prep, and Dutch vocabulary side by side, and knojo blends what's due across them into one short daily stack.
A daily read on what needs you
Every morning knojo gives you a plain-language summary of what's due, what's hard, and what's about to slip — so you always know the smallest next step instead of staring at a wall of cards.
Getting started with knojo
You start free with your first learning goal, manual and AI-generated cards to try it, the daily spaced-repetition queue, and one daily reminder. When your queue outgrows the free limits, Pro unlocks unlimited cards and goals, more AI generation, AI quiz mode, and smart due-card reminders.

Frequently asked questions
What is knojo?+
knojo is a spaced-repetition learning app that turns your notes into flashcards automatically with AI and schedules reviews so you remember what you learn. It's designed around a five-minute daily habit and is launching soon on iOS and Android.
How does knojo turn notes into flashcards?+
You paste in notes, an article excerpt, or a lesson recap, and knojo's AI converts the text into clean question-and-answer cards in seconds. You can review and edit the generated cards or write your own from scratch.
Does knojo use spaced repetition?+
Yes. After you rate each card as Forgot, Hard, Good, or Easy, knojo schedules the next review using spaced repetition, bringing each card back just before you'd forget it so reviews stay short and effective.
How much does knojo cost?+
knojo has a free plan that includes your first learning goal, AI and manual cards, the daily review queue, and one daily reminder. Pro is €3.33/month billed yearly (€39.99/year) or €5.99 month-to-month, and adds unlimited cards and goals, more AI generation, AI quiz mode, and smart reminders.
Can I study more than one subject at a time?+
Yes. knojo uses learning goals so each subject keeps its own queue. You can run several goals in parallel — for example an exam, an interview prep deck, and a language — and knojo combines what's due into one short daily session.
