Features

Everything You Need to Learn

From smart flashcard creation to advanced spaced repetition algorithms — all in one platform.

📥

Smart Import

Paste TXT, CSV, DOCX files or Google Docs links — AnkiFlow automatically separates terms and definitions. Even works with word = translation format.

🧠

Spaced Repetition (SRS)

Based on SM-2 algorithm. Shows what you don't know more often, what you know less frequently. Saves your time, increases efficiency.

📋

Bulk Paste

Paste multi-line text at once — each line becomes a separate card. Import 20+ cards instantly.

🔊

Text-to-Speech

Learn by listening. Hear pronunciation in any language — ideal for language learning.

☁️

Cloud Sync

All your cards are automatically saved. Create on computer, study on phone — synced everywhere.

📊

Statistics

Daily goals, streaks, review history, accuracy percentage — track your progress.

Scientific Foundation

SM-2: Science-Based Memory Algorithm

Developed by scientist Piotr Woźniak in 1987. Based on Ebbinghaus's forgetting curve.

🧪 Problem: The Forgetting Curve

After learning something, without review:

After 1 hour
50% forgotten
After 1 day
70% forgotten
After 1 week
90% forgotten

✅ Solution: Optimal Repetition

SM-2 algorithm shows cards before you forget:

1
New card1 minute → 10 minutes → Graduate
2
1st reviewAfter 1 day
3
2nd reviewAfter 6 days
4
3rd reviewAfter 15 days
5
4th reviewAfter 38 days...

How Do Rating Buttons Work?

Again

Couldn't remember at all

→ Restarts after 1 minute
→ Returns after 3-8 cards in session
Hard

Remembered with difficulty

→ Reviews sooner
→ Returns after 5-12 cards in session
Good

Remembered normally

→ Moves to next step
→ 1 day → 6 days → 15 days...
Easy

Very easy

→ Graduates faster
→ Interval increases with 1.3x bonus
Why?

Not Just Repetition, Smart Repetition

⏱️

Save Time

Only see cards you're about to forget. Don't waste time on what you already know.

📈

95% Efficiency

Research shows people who learn with SRS retain 95% of information over the long term.

🎯

Personalized

Ease Factor adapts to each card individually. Words you find difficult repeat more often, easy ones less frequently.

🌍

For Any Subject

Languages, medicine, programming, history — any field that can be learned with flashcards.
