Anki FSRS Explained

TL;DR: Quick Start to FSRS in Anki

Short on time? Here's how to quickly enable FSRS for your Anki flashcards:

  1. Adjust Learning Steps for New Cards
    • Go to your deck options in Anki (click the gear icon → Options), and in the New Cards section, ensure the learning steps are set to be under 1 day.
    • Tip: Avoid using 23-hour steps to make sure all steps are completed within the same day.
    • If your default learning steps are 1 minute and 10 minutes, no changes are necessary.
  2. Open the FSRS or Advanced Section
    • Navigate to the "Advanced" section in your deck options, or directly access "FSRS" if you're using Anki 24.04 or later.
  3. Optimize FSRS Settings
    • Click on the "Optimize" button in the FSRS section to automatically adjust settings based on your review data.
    • If an error occurs, it usually means you have fewer than 1000 reviews (or 400 if using Anki 24.04). In this case, use the default parameters.
  4. Set Your Desired Retention Rate
    • Adjust the retention rate to balance recall effectiveness with review frequency.
    • Recommended: Aim for a retention rate between 80-95%, with 90% being optimal for most users.

 

What Is FSRS? 🧐

FSRS, short for "Free Spaced Repetition Scheduler" enhances your Anki flashcards by personalizing review schedules for improved memory retention.

 

How FSRS Works 🌟

  • Retrievability: Indicates your ability to recall information at any moment.
  • Stability: Measures the duration your memory retains information before it starts fading.
  • Difficulty: Assesses how challenging it is to learn and remember content.

FSRS optimizes your study sessions by adjusting review times based on these aspects of memory.

 

FSRS Habits: Avoiding Common Pitfalls ❗

FSRS adapts to most study habits, except for incorrectly using the "Hard" button. If you press "Hard" by mistake when failing to recall, FSRS extends review intervals, thinking you've recalled with difficulty. This misjudgment disrupts your study efficiency. Always choose "Again" for failed recalls to keep review intervals properly aligned with your learning pace.

 

FSRS vs. SuperMemo: A Detailed Comparison 🔍

  FSRS SuperMemo
Personalization Adapts uniquely to individual learning patterns. Uses a fixed algorithm with some adaptability based on user performance.
Review Efficiency 20-30% fewer reviews needed for similar retention rates. More reviews may be required to achieve similar retention.
Adaptability to Breaks Efficiently adjusts schedules after breaks without overwhelming the user. May require more time to re-adjust and can result in review backlogs.
User Control Allows setting desired retention rates directly affecting review intervals. Retention rate adjustments are indirect, based on algorithmic calculations and user feedback.

To activate FSRS, ensure you're using Anki version 23.10 or newer and ensure all of your Anki clients are Anki(Mobile) 23.10+ or AnkiDroid 2.17+. For an enhanced experience, consider the FSRS4Anki Helper add-on for insights and optimal retention settings.
