Cards and Flashcards

On the journey of knowledge review, everyone has their own rhythm. To make memorization more scientific and effortless, we’ve designed a card system that combines flexibility with deep optimization capabilities. It not only seamlessly transforms your notes into review tools but also grows alongside your memory curve.

📝 From Basic to Advanced, Covering All Learning Scenarios

We don’t just offer simple “front-and-back” flipping; based on real learning and exam needs, we provide a rich variety of question types:

Basic Flashcards

• Single-sided flashcard: A flashcard with only one side, suitable for rapid recitation.
• Double-sided flashcard: The classic front-and-back flashcard — front side is the question, back side is the answer, perfect for concept memorization.
• Cloze deletion: Hides key words in a sentence; you fill in the blanks based on context, great for contextual memory.

Advanced Cards

• More multiple-choice question types: Simulates objective exams realistically, helping you distinguish confusing distractors.
• More fill-in-the-blank types: Supports multiple cloze deletions in one card, ideal for memorizing complex formulas, legal provisions, or multi-step processes.
• More foreign language-specific types: Designed for language learners, supports structured deconstruction of words, phrases, and long difficult sentences, and provides clear pronunciation support to help you overcome “mute foreign language”.

🔒 Privacy and Security

We deeply understand that your learning data and notes belong to you alone. Throughout the entire card creation and review process:

• Your local notes and card content remain stored on your device at all times.
• The server-side parameter optimizer only requires anonymized pure review history records (e.g., on which day a card was reviewed, and whether the rating was “recalled” or “forgotten”), and will never touch your specific note texts or sensitive content, ensuring your data is safe and worry-free.
