What is Spaced Repetition for Knowledge Management?

Spaced repetition schedules reviews at increasing intervals. It works well when the goal is recall and the material can be tested, as with a flashcard.

Knowledge management has a broader problem. A saved article, Note, quotation, or decision is not always something to memorize. It may need to support current work, connect to another idea, remain searchable as reference, or disappear from attention while staying in the archive.

Use spacing for memory, relevance for knowledge

A fixed interval can remind you that an item exists. It cannot explain why the item matters today.

A useful knowledge review considers more than elapsed time:

• an explicit link to active work;
• a recurring concept across recent material;
• a Note that has gained new backlinks;
• a visible gap in collected evidence;
• an older source that may now answer a current question.

The reason should be visible. “Related to three recent Notes” is more actionable than an unexplained score.

How Arivu supports learning

Home leads to recent material and ordinary dated notes. Review is an optional secondary view, not a study queue.

At /learn, an optional three-question quiz uses fixed passages you preview before consenting to the configured AI destination. Answers remain hidden until you submit all three choices.

This is not a universal spaced-repetition scheduler. It is a way to revisit material because it may be useful, then inspect why it returned.

Graph can guide a review

Focus Graph around one Note, concept, entity, or source. Inspect the relationships, provenance, and confidence, then open the underlying material. A list alternative is available when exact relationships matter more than the visualization.

Add an explicit link if the review reveals a meaningful connection. That records your judgment for the next visit.

Where optional AI fits

An optional provider can improve summaries, embeddings, explanations, and synthesis. Embeddings may reveal similarity relationships between differently worded items.

None of that is required for explicit links, local full-text Search, graph structure, or Review. Source chat and quiz generation do require a configured provider.

A lightweight review habit

Once a week:

1. Open one saved source relevant to current work.
2. Recall its main point, then check the text.
3. Search for a related phrase in the Library.
4. Focus Graph around the strongest item.
5. Write or update one durable Note.
6. Try a source quiz if you want to check your recall.

Use flashcards when you need tested recall. Use a knowledge review when you need sources and ideas to become relevant again.

Continue with Review and the daily workflow.
