How to Use Spaced Repetition for Reading
Spaced review can help reinforce ideas from reading. Focus on useful units such as definitions, key claims, quotations, and glossary terms, then review at a sustainable cadence. Here is a practical workflow.
- · A recall or spaced-review tool, such as Summio Companion or Anki
- · The books or articles you want to retain
Read first, summarise second
Read the book at the depth you actually need (short for triage, detailed for study). The reading does the work; the cards are for not forgetting it. Summarise after reading — the summary surfaces the units worth turning into cards.
Pick the right card units
For non-fiction: definitions, the strongest claim per chapter, a memorable quote, or a key statistic. For history: dates and causes. For technical books: key formulas or concepts. Choose a small set you can review consistently; the useful amount varies by material and learner.
Use active recall prompts
Turn an idea into a prompt that requires retrieval, then reveal and check the answer. Summio Companion can prepare recall questions and review cards from saved summaries; other spaced-review tools offer their own card formats.
Review on a sustainable schedule
Review the material due in your chosen tool, then adjust the cadence to a workload you can sustain. Scheduling behavior differs by product and may change over time.
Don't over-add
Every new card adds future reviews. Start with a small daily amount, watch the backlog, and adjust it to a pace you can sustain.
- Prompts from material you read carefully may be easier to recall because you have more context than a summary alone can provide.
- Don't make cards for everything interesting. Make cards for what you want to remember in 6 months.
- Scheduling and card formats differ between products. Choose a workflow you can maintain and check the current product documentation for algorithm details.
Common questions
Does spaced repetition work for fiction?
Less well than non-fiction. Fiction works through cumulative experience, not discrete facts. Use SRS for things you want to recall verbatim — quotes, key plot points, character names — but most of fiction's value is in the reading itself.
How long until I see results?
Regular review reinforces long-term recall compared with leaving material unreviewed. Results vary by person, material, and review schedule.
Is Summio Companion the same as Anki?
No. Summio Companion builds recall, review, and practice from saved Summio summaries, while Anki is a separate configurable flashcard system. Compare their current card and scheduling behavior for your workflow.
