What is spaced repetition?

Spaced repetition is a study technique that schedules reviews based on how well you know each item. Cards you rate as Easy are shown less often, while cards you rate as Hard or Wrong are shown again sooner. This concentrates your study time on the material you actually need to practice, making learning more efficient than rereading everything at the same pace.

Will my flashcards be saved if I close the browser?

Yes. All decks, cards, and study progress are saved automatically in your browser's localStorage. Your data persists across sessions as long as you use the same browser and do not clear site data. For long-term backup or use on another device, use the Export button to download your decks as a JSON file, then Import on the other device.

How many cards and decks can I create?

There is no hard limit imposed by this tool. The practical limit depends on your browser's localStorage quota, which is typically 5-10 MB. For most learners, this comfortably holds thousands of cards across many decks.

Can I share my flashcard decks with others?

Yes. Click "Export" to download your selected deck as a JSON file, then share that file with anyone. They can import it using the Import button on their own device. The JSON format is plain text, so you can also inspect or edit it in any text editor.

Summary

This free flashcard maker lets you build study decks in your browser and review them with spaced repetition. Add question-and-answer cards, run study sessions, flip each card, and mark it Easy, Hard, or Wrong so the tool schedules difficult cards more often. Every deck is saved locally in your browser, so there is no signup and no data leaves your device.

How it works

Create a new deck by typing a name in the Deck Name field and clicking "Create Deck". Your deck appears in the deck selector.
Select your deck, then enter the front and back text for a card and click "Add Card". Repeat for each card you want to study.
Click "Start Studying" to enter study mode. Click the card (or press Space) to flip it and reveal the answer.
After seeing the answer, rate it Easy, Hard, or Wrong. The rating changes how frequently that card is included in upcoming study sessions.
Review your progress in the Stats panel — track mastery percentage, today's study count, and your current streak.

Use cases

Language learning: build vocabulary decks with the foreign word on the front and the English translation on the back, then drill with spaced repetition until words stick.
Exam preparation: convert lecture notes into question-and-answer cards, then work through the deck daily in the weeks before a test to consolidate knowledge.
Professional certification: create topic-based decks for definitions and concepts, use the Hard and Wrong ratings to surface weak areas automatically.
