The most powerful spaced repetition system available! Scientific memory scheduling that adapts to your personal learning patterns for maximum retention.

The Science of Memory: Why Anki Works

Active Recall Testing

Active recall is the process of actively stimulating memory during learning. Instead of passively reading or reviewing material, you force your brain to retrieve information from memory. This retrieval process strengthens neural pathways far more effectively than passive review.

The Testing Effect

Research shows that retrieving information from memory improves long-term retention by 50% compared to passive review. Each successful recall strengthens the memory trace, making future recalls easier and more automatic.

Desirable Difficulties

The slight struggle to recall information is actually beneficial. This "desirable difficulty" forces deeper processing and creates stronger, more durable memories. Easy reviewing feels productive but creates weak memories.

Spaced Repetition Algorithm

Spaced repetition leverages the psychological spacing effect - we remember information better when reviews are spaced out over time rather than massed together. Anki's algorithm calculates optimal review intervals based on your performance.

The Forgetting Curve

Hermann Ebbinghaus discovered that memory retention decreases exponentially over time. Without review, we forget 50% of new information within an hour, 70% within 24 hours, and 90% within a week. Spaced repetition interrupts this curve at optimal moments.

First Review:1 day (before 50% is forgotten)
Second Review:3 days (reinforces at 80% retention)
Third Review:1 week (strengthens long-term memory)
Fourth Review:1 month (moves to permanent memory)

Efficiency Maximization

Review only when you're about to forget, not before (waste) or after (relearning). This minimizes time while maximizing retention.

Adaptive Intervals

Easy cards get longer intervals, hard cards shorter ones. The algorithm adapts to each item's difficulty for you personally.

Compound Growth

Each successful review increases the next interval exponentially, eventually reaching months or years between reviews.

Applying Anki to Chinese Learning

Character Cards Best Practices

Front: Character only

Show just 学 - force recall of pronunciation and meaning

Back: Complete information

Pinyin (xué), meaning (study), audio, example sentence

Use multiple card types

Recognition (character→meaning) and production (meaning→character)

Tone Training Cards

Audio on front

Play native pronunciation, recall character and tone number

Minimal pairs

Create cards contrasting mā/má/mǎ/mà for tone discrimination

Sentence Mining

Instead of isolated words, use sentences from real Chinese content. Highlight the target word but keep the full context. This builds natural usage patterns and collocation knowledge alongside vocabulary.

Technical Configuration

Key Algorithm Settings

Interval Modifier: 100%

Default is optimal for most learners. Decrease if forgetting too much.

Starting Ease: 250%

How quickly intervals grow. Lower for harder material like Chinese.

New Cards/Day: 10-20

Sustainable pace prevents review avalanche. Quality over quantity.

Maximum Interval: 365 days

Prevents cards from disappearing forever. Annual review maintains knowledge.

Card Types for Chinese

Basic (Front/Back)

Simple recognition cards for characters and vocabulary

Basic (and reversed)

Creates both recognition and production cards automatically

Cloze Deletion

Fill-in-the-blank for grammar patterns and sentence structures

Image Occlusion

Hide parts of character stroke order diagrams for practice

Avoiding Common Pitfalls

Don't add too many new cards daily - reviews compound quickly

Don't make cards too complex - one piece of information per card

Don't skip difficult cards - use "Hard" button, not "Again" repeatedly

Don't review when tired - poor performance skews the algorithm

Advanced Anki Techniques for Chinese Mastery

Morphological Analysis

Break compound words into components. For 电脑 (computer), create linked cards for 电 (electric) and 脑 (brain) to understand the logic behind word formation.

Leech Management

Cards failed 8+ times become "leeches" - they waste time. Rewrite them with better mnemonics, add more context, or break into smaller pieces.

Media Enhanced Cards

Add audio from native speakers, character stroke animations, and contextual images. Multi-sensory encoding creates stronger memories.

Progressive Difficulty

Start with recognition cards, add production cards after mastery, then cloze deletions for usage. Build complexity gradually.

Contextual Clustering

Group related vocabulary by theme or usage situation. Learning 买/卖/购/售 together shows the relationships between buying and selling concepts.

Review Optimization

Review at the same time daily for habit formation. Morning reviews have better retention. Keep sessions under 30 minutes for sustained focus.

'Anki' means 'memorization' in Japanese, but it's perfect for Chinese learning - systematic repetition has been the foundation of Chinese education for millennia!

Expert Assessment

For disciplined learners seeking mastery, this tool follows the ancient Chinese principle: '温故而知新' - review the old to learn the new.

"温故而知新" - Review the old to learn the new. Anki embodies this ancient Chinese wisdom through modern science.
