Online Flashcards for Creating and Reviewing Study Cards
Flashcard Study Tool
What is flashcard learning?
Flashcards are a learning method that divides knowledge into a question or prompt on the front and an answer on the back. The front can contain an English word, concept, question, or hint, while the back can contain a definition, answer, or additional explanation. During practice, try to recall the answer from the front before flipping the card to check the back. This makes it easier to identify knowledge you have not fully mastered.
How to create study cards
Enter the front and back of a card in the deck management area and click Add to create a flashcard. When creating many cards, you can paste multiple lines at once, using a vertical bar to separate the front and back, such as “apple|apple in Chinese”. You can also import a TXT file directly, which is useful for organizing vocabulary lists, terminology, and course notes.
Four study modes
The tool provides four modes: New Cards, Today's Review, All Cards, and Review Incorrect. New Cards are used for content that has not been reviewed yet. Today's Review handles cards that are due for review. All Cards lets you browse the entire deck, while Review Incorrect focuses on cards with lower mastery.
Know, Unsure, and Don't Know
After revealing the answer, choose Know, Unsure, or Don't Know based on your actual level of mastery. Cards marked Know leave the current practice round. Unsure cards appear again later, while Don't Know cards return to the end of the current queue for another attempt. The tool also records review counts, correct and incorrect attempts, memory level, and the next review time for future practice.
Keyboard shortcuts for faster review
On desktop devices, press Space to flip the current card. Number keys 1, 2, and 3 correspond to Don't Know, Unsure, and Know. Left and right arrow keys can also be used for quick ratings. On phones and tablets, simply tap the card to flip it and then tap the rating button.
Import, export, and manage decks
Decks support adding, editing, copying, and deleting cards individually, as well as bulk pasting and TXT import. When random order is enabled, the current practice queue can be shuffled. The export function saves the deck as a TXT file, with one card per line containing its front and back, making it easy to back up or migrate your cards.
Where is study data stored?
Flashcards, review counts, and memory status are stored in the current browser's local storage. No account is required, and card content is not uploaded to a server. Saved cards and review status remain available after refreshing the page. The current practice queue itself is not saved as progress; when you reopen the page, a new queue is created according to the selected mode.
How to organize a flashcard deck
When you have many cards, organize them by course, chapter, subject, or knowledge topic. Try to put only one recallable concept on each card. Keep the front concise and provide an accurate answer or necessary explanation on the back. This makes the cards easier to review quickly and continuously.
How do you use the flashcard study tool?
Create study cards with a front and back. During practice, recall the front content before flipping the card to check the answer, then choose Know, Unsure, or Don't Know based on your mastery. The tool uses your ratings to manage cards in the current round and saves review counts and future memory status.
