Active Recall and Spaced Repetition
Recall utilizes two learning techniques, Active Recall and Spaced Repetition, to help you remember the content that you save to your knowledge base. This system prompts you with questions generated from your saved content, following a schedule that adapts to how well you know the material.
What is Active Recall?
Active Recall is a learning method where you try to remember information without referencing the material. This technique has been shown to significantly enhance long-term retention compared to passive reading. Actively retrieving information helps strengthen neural pathways, thereby improving recall and promoting the transfer of knowledge to long-term memory.
What is Spaced Repetition?
Spaced Repetition involves reviewing information at progressively increasing intervals. This method leverages the psychological spacing effect, where revisiting material just before it is forgotten enhances memory retention. By strategically timing reviews, Spaced Repetition helps cement information in memory.
Generating Questions
To add a card to your review schedule:
- Open any card and go to the Quiz tab
- Click Generate Questions. The AI will create questions in various formats from the card’s content.
- Toggle Schedule for review in the generate modal to add them to your spaced repetition cycle
You can also create questions manually using the Create button if you want to test yourself on specific concepts.
Repeat this for any card you want to remember long-term. The more cards you add to your review schedule, the more comprehensive your study sessions become.
Knowledge Stages
Every question progresses through five stages based on your answers. Each stage determines how frequently the question appears:
| Stage | Criteria | Review Interval |
|---|---|---|
| New | Not yet reviewed | Immediate |
| Learning | Last answer was incorrect | ~1 day |
| Practiced | 1-2 correct in a row | 3-7 days |
| Confident | 3-4 correct in a row | 14 days - 1 month |
| Mastered | 5+ correct in a row | ~3 months |
If you get a mastered question wrong, it drops back to Learning so you can reinforce it.
Reviewing a Card
After generating questions for a card, you can quiz yourself on that card right away from the Quiz tab. This is useful for an initial review of new material before it enters the spaced repetition cycle.
The Review Dashboard
All scheduled questions across your cards are grouped into your Recall Review, accessible by clicking the Review icon in the left sidebar. The review dashboard gives you an overview of your entire review schedule: how many questions are ready for review, what’s coming up this week, and your overall progress across all cards.
From the dashboard you can browse all your questions, filter by status or tag, track your streak, and monitor how your knowledge is progressing over time.
Click Start Review to begin a session with your most-due questions. Questions appear one at a time in a full-screen quiz session.
Question Types
Recall supports seven question formats: Multiple Choice, True/False, Fill in the Blank, Short Answer, Matching, Ordering, and Flashcard. You choose which types to include when generating questions.
Challenges
You can share your quiz questions as a challenge: a shareable link that lets anyone take the same quiz and compete on a leaderboard. No sign-up is required for participants. Challenges are separate from your personal review schedule.
