FlashLearn — Free Flashcard Maker with Spaced Repetition

How to Use FlashLearn

1. Create a new deck or use the included starter decks (Spanish Basics, JavaScript Concepts).
2. Add cards with a front (question/term) and back (answer/definition).
3. Start a study session and flip each card to reveal the answer.
4. Rate your recall: Easy, Good, Hard, or Again — the SM-2 algorithm schedules the next review.

Why Spaced Repetition Beats Cramming

Spaced repetition is the most scientifically proven method for long-term memorization. Instead of reviewing everything every day (wasteful) or cramming the night before (forgettable), you review each card at the optimal moment — just as you are about to forget it. FlashLearn uses the SM-2 algorithm, the same algorithm behind Anki, to calculate the perfect interval for each card.

The result is dramatic: studies show spaced repetition requires 40% fewer reviews to achieve the same retention as massed practice. For vocabulary, medical terms, historical dates, or coding concepts — anything where memorization matters — FlashLearn's system gets material into long-term memory efficiently.

Frequently Asked Questions

• What is the SM-2 algorithm?
  SM-2 (SuperMemo 2) calculates the optimal review interval based on your rating. Easy cards get longer intervals; difficult cards get reviewed sooner. The algorithm adjusts each card's "ease factor" over time.
• Can I import my own decks?
  Yes. Decks can be imported and exported as JSON files. You can also create decks manually using the deck editor.
• Will my progress be saved?
  Yes. All decks and study progress are saved in your browser's localStorage and persist between sessions.
