Love hearing the pronunciation and getting context explanations!

Recalling vocabulary is hard

You have to learn ~2k words to hold 90% of conversations

📚

Spend hours reading and listening to new words

😮‍💨

You forget them all after a few days

😔

You get discouraged and give up

Stop wasting hours building flashcards manually

Before

  • ❌ Spending hours searching for audio files
  • ❌ Manually looking up translations one by one
  • ❌ Building decks from scratch takes forever
  • ❌ No idea when to review cards optimally
  • ❌ Stuck with generic, boring content
  • ❌ Getting confused with no way to get explanations
  • ❌ Forgetting cards just after you thought you knew them

After

  • ✅ Built-in text-to-speech for instant audio
  • ✅ AI creates cards just by describing what you want
  • ✅ 100s of pre-built decks with common phrases
  • ✅ FSRS algorithm shows cards just before you forget
  • ✅ Access to 20 different languages instantly
  • ✅ Ask AI to explain any confusing card
  • ✅ Smart spaced repetition maximizes retention

The Science Behind Spaced Repetition

Backed by decades of research, spaced repetition transforms how your brain retains information

Memory Boost

200%

Improvement in long-term retention vs cramming

Recall Rate

85-90%

Success rate per review session with SRS

Effectiveness

89%

More effective than traditional cramming methods

Research Studies

259+

Experiments confirming SRS superiority

📊 Cramming vs Spaced Repetition

Typical Review Session

Without SRS
With SRS
85-90% recall

Short-term (few days)

Without SRS
20-40% retention
With SRS
80-90% retention

Long-term (months/years)

Without SRS
<10% retention
With SRS
Significantly higher

Vocabulary (9 years)

Without SRS
Poor retention
With SRS
Strong retention

Memory + Mnemonics (158 days)

Without SRS
With SRS
77% retention

🧠 How It Works

1

Testing Effect

Active recall strengthens memory pathways

2

Spacing Effect

Strategic timing optimizes retention

3

Retrieval Effort

Difficulty enhances synaptic consolidation

🎯 The Bottom Line

2-4x

Better retention than cramming

Transform 30-40% recall into consistent 80-90% retention with scientifically-proven spaced repetition
