About This Website
This website is designed to help you master anything through spaced repetition — a powerful learning technique based on reviewing information at increasing intervals to optimize memory retention.
You can:
- Create and manage your own list of terms or concepts.
- Quiz yourself using different algorithms, including smart ones that adapt to your strengths and weaknesses.
- Track your learning progress over time.
The platform is ideal for students, language learners, test preppers, or anyone who wants to improve their memory and long-term learning.
What is Spaced Repetition?
Spaced repetition is a learning method that helps you retain information long-term by reviewing it just before you’re likely to forget it. Each time you successfully recall a term, the system increases the interval before it’s shown again — starting with hours, then days, then weeks or longer. If you miss a term, the interval shortens so you can review it again sooner. This technique leverages the brain’s natural forgetting curve, making your study sessions more efficient by focusing on what you’re close to forgetting and gradually reinforcing what you already know.
Why this Spaced Repetition Algorithm is Better
- Similar to other software, this site increases the duration between review sessions by a factor of 1.5 each successful attempt.
- However, when you fail and have to restart, it fast tracks your progress so that the duration increases by a factor of 2.5 each successful attempt until you reach your previous high.
- This makes it less frustrating to forget a word - you know you aren't totally "restarting" since your progress will be fast tracked until you reach your previous state.
- To my knowledge, this is the only site that does this.
Multiple Types of Algorithms
Also, unlike other websites, I provide a variety of different algorithms for review. This is designed for users preparing for imminent exams who will need to review all of their cards in one session.
- Spaced Repetition - the algorithm only shows terms that are "due" meaning a sufficiently long time has elapsed since they were last reviewed. The time in between review sessions of course will increase with each successful attempt and will decrease with failed attempts.
- Fail in Last 3 Attempts - the user goes through each card until the consecutive last 3 attempts were all successes, at which point the quiz is over.
- Highest Proportion Failures (Infinite) - the site selects the term with the highest proportion of failures (which only looks at the last 10 attempts, with more recent terms weighted higher than the older terms). This is repeated forever, therefore always focussing the user on the terms they have the hardest time on.
- Worst Success Streak (Infinite) - this selects the term that has the lowest streak of successful attempts. It loops infinitely doing this.
- Random - this selects random cards and loops infinitely.
Repeating Terms: for all these algorithms, users can select the number of cards they have to see before a term repeats.
