How to Use Spaced Repetition
The Review tab implements the SuperMemo-2 (SM-2) spaced repetition algorithm to schedule when you should re-read each captured node. The more confidently you remember something, the longer the interval before it appears again.
Starting a Review Session​
- Navigate to the Review tab in the dashboard.
- If you have nodes due today, a review card appears.
- If there are no nodes due, the tab shows an empty state with your current streak.
The Flashcard Flow​
Each review session works as a flashcard:
- The card shows: The node's title and source URL.
- Click "Reveal": The AI-generated summary is revealed.
- Rate your recall: Choose one of four ratings:
| Rating | Meaning | Effect on Interval |
|---|---|---|
| Forgot | I had no memory of this. | Resets interval to 1 day. |
| Hard | I remembered but it was difficult. | Short interval increase. |
| Good | I remembered with some effort. | Moderate interval increase. |
| Easy | I remembered effortlessly. | Large interval increase. |
SM-2 Algorithm Details​
The interval and ease factor are updated after each rating according to the SM-2 formula:
- Ease Factor starts at 2.5 and adjusts based on your ratings.
- Interval grows exponentially for "Good" and "Easy" ratings.
- Forgot resets the interval to 1 day and lowers the ease factor.
The next_review_date for each node is stored in the reviews table and queried daily.
Review Streak​
The dashboard shows your current review streak — the number of consecutive days you have completed at least one review. Maintaining a streak helps build a consistent habit.
Tips​
- Capture frequently: The more nodes you have, the more valuable the review system becomes.
- Be honest with your ratings: Over-rating yourself defeats the purpose of spaced repetition.
- Review daily: Even 5 minutes per day is enough to make steady progress.
How Reviews Are Created​
When you capture a new node, a reviews entry is automatically created with:
interval = 1(day)ease_factor = 2.5next_review_date = today
The node will appear in your review queue on the same day it is captured.
