Is it because I'm not smart...?

No, that's not it. The cause lies in 'how the brain works'

Why do we forget?

Why forget?
Because we don't review
Why don't we review?
Because we think 'I understood it once, so I'm fine'
However...
The brain distinguishes between 'understanding' and 'memory retention'

How memory works according to neuroscience

  • Memory at the moment of understanding is 'short-term memory'
  • Information that isn't repeated is judged 'unnecessary' and deleted
  • When the same information is input repeatedly, the brain judges it 'important'
  • Synapses (neural connections) are strengthened and become 'long-term memory'

...therefore

Review is essential.

※Based on Ebbinghaus's forgetting curve and synaptic plasticity research

Why do we think we're 'fine' without reviewing?

Feeling like you've 'already memorized it' right after studying is a brain illusion proven in cognitive psychology.

In other words, the feeling of being 'fine' is the biggest reason people don't review. Recognizing this illusion is the first step to effective learning.

Why does the brain judge unrepeated information as 'unnecessary'?
▼ Learn more

The reasons why the brain actively erases memories have been revealed by recent neuroscience research.

  • 1. Prevention of Cognitive Overload:The hippocampus selectively erases unnecessary information to improve the storage and retrieval of relevant memories. This prevents cognitive overload. Davis RL (2017) The Biology of Forgetting
  • 2. Behavioral Flexibility:Being bound by old information prevents adaptation to new situations. Forgetting enables 'relearning' and enhances adaptability to environmental changes. Anderson MC (2021) Active Forgetting
  • 3. Goal Achievement Efficiency:Processes controlling goal-oriented behavior actively forget memories that interfere with behavioral goals. This is a mechanism for maintaining concentration. Bekinschtein P (2018) Nature Communications
  • 4. Emotional Regulation:Remembering unpleasant memories vividly for a long time is mentally distressing. Forgetting is also a function that protects mental health. Nørby S (2015) On the Adaptive Value of Memory Loss

つまり、忘却は脳の「欠陥」ではなく「設計」です。だからこそ、復習によって「これは重要だ」と脳に認識させる必要があるのです。

Can 'understand' but
can't 'use'?

'Understanding' and 'Using' are different

※ Especially in language learning

?
Receptive vocabulary (understand)
However
Productive vocabulary (can't use)

5 Levels of Vocabulary Knowledge (VKS)

Level ❶ Never seen it
Level ❷ Seen it but don't know meaning
Level ❸ Can answer if given choices
→ Receptive vocabulary = Can read/listenMost Japanese stop here
Level ❹ Can explain meaning accurately
Level ❺ Can use correctly in sentences
→ Productive vocabulary = Can speak/writeMost Japanese can't 'use' (speak/write)

💡 In simple terms...

Memory has levels.

Even if you think you've 'memorized' it, whether you stopped at ❸ or reached ❺ makes a huge difference in test and practical results.

Even if you get the 'correct' answer on multiple choice, it's meaningless if you can't actually use it.

Ankimo uses a 'see the question, recall the answer yourself' format.
We support vocabulary acquisition at a 'usable' level.

Easy to Use

Start learning right away with simple Q&A format input.

Just enter what you want to remember in a Q&A format (with an optional hint) to get started. This simple design produces two independent learning effects: ① Creating your own questions and answers deepens memory retention through the 'Generation Effect' (Slamecka & Graf, 1978); ② Recalling answers in Q&A format at each reminder further consolidates memory through the 'Testing Effect' — students who studied via self-testing had only a 13% forgetting rate after two days, compared to 56% for those who only re-read (Roediger & Karpicke, 2006). Simple input, backed by two independent scientific principles. You can also attach images or audio files to questions, answers, and hints.

Reminder notification arriving at the optimal timing

Support Until You Remember

A learning app focused on memory retention. Using scientifically proven spaced repetition, it ensures reliable memory retention.

We forget about 74% of what we learn within a day (Ebbinghaus, 1885). However, reviewing at the right intervals can dramatically prevent forgetting (Cepeda et al., 2006). Ankimo applies this principle, reminding you at optimal intervals to convert short-term memory into long-term retention.

Review intervals adapting to memory level

Boost Learning Efficiency

Optimize review intervals based on how easily you remember, mastering more content in the same time.

This system is based on the 'box system' devised by Leitner in 1972. Items that are hard to remember are reviewed frequently at short intervals, while well-remembered items are reviewed at longer intervals. By automatically adjusting review frequency to your memory level, it maximizes the effect of limited study time. This experience of expanding review intervals also creates a game-like feeling of leveling up — making it easier to stay motivated and keep going.

Reviewing on a smartphone during commute

Make Use of Spare Time

Review easily anytime, anywhere.

Review during commutes, waiting times, or short breaks. Just like checking emails, even a few minutes of spare time can become learning time. Small daily accumulations lead to big learning results.

Accessible on PC, tablet, and smartphone

Use Anywhere

Continue learning seamlessly across any device.

With any internet connection (WiFi, mobile data, etc.), you can access from any device - PC, tablet, or smartphone. Register new items on your home PC and review on your smartphone while out. No app download required.

Managing many learning items in a list view

Easy Management

Efficiently manage many learning items and ensure memory retention.

When learning large amounts (e.g., 1,000+ English words), it's not easy to judge what you've memorized, what still needs review, and how much time to spend on each item. Ankimo automates this complex process with self-assessment and reminder features. Just focus on learning for efficient memory retention. For those with existing study data from other tools or wanting to manage separate accounts, TSV import/export is available from the posts list menu.

Using hints to recall answers step by step

Try Creating Hints

Creating your own hints deepens memory retention further.

Hints provide two independent benefits: ① The benefit of creating hints yourself — self-generated memory cues support recall more powerfully than cues created by others, and this effect persists for up to 3 weeks after learning (Tullis & Qiu, 2021). ② The benefit of recalling through hints — thinking through a hint rather than simply seeing the answer deepens processing and improves retention. According to Craik & Lockhart's (1972) Levels of Processing theory, the more you engage with meaning and connect it to existing knowledge, the stronger the memory formed.

Expert

Enable deeper learning

Example of output-focused Q&A design

Try Designing Q&As

Output-focused Q&A design elevates knowledge to 'usable' level.

Go beyond simple memorization - design Q&As that help you actually use what you've learned. For example, 'Make a sentence using this word' or for history, 'Explain the impact of this historical event on modern society.' Output-type questions lead to more practical, deeper understanding.

Example of creating applied questions for deeper understanding

Create Questions for Deep Understanding

Create Q&As that help you grow, like challenging a study rival with quizzes.

The key is creating questions that dig into 'why' rather than just memorizing. By understanding not just facts but also relationships and context, you develop applicable knowledge. See input tips
