Cards and Optimization

Everyone has their own pace when reviewing knowledge. To make memory tracking more scientific and effortless, we designed a flashcard system that combines flexibility with deep optimization. It not only seamlessly converts your notes into review tools but also grows alongside your memory curve.

📄 One-Click Note-to-Card Conversion for Frictionless Review

You don’t need to dedicate extra time to “crafting” flashcards. While taking daily notes or structuring outlines, simply click to generate a flashcard directly from a note paragraph (or a specific block) whenever you encounter a key point.

Maintain Contextual Links: Flashcards remain linked to their source notes. If you forget the context during review, you can jump back to the original note with a single click to see the full background.
Eliminate Duplicate Work: When you update note content, the associated flashcards sync automatically, eliminating the need for double editing.

🧠 Dual-Algorithm Support: Trusting the Science That Suits You Best

Different types of knowledge require different memory rhythms. With two built-in algorithms, you can switch freely based on your needs:

TSRS Algorithm: Perfect if you are a new user or prefer a more straightforward, intuitive approach to learning.
FSRS Algorithm: Ideal for knowledge requiring long-term, stable retention (such as foreign languages, professional certification exams, and underlying principles). It optimizes intervals based on your review history, extending the gaps and minimizing unnecessary repetition.

A Smarter “Parameter Optimizer” An algorithm’s effectiveness depends on how well it understands you. As your review history grows, the system performs anonymous data analysis on the server side (without consuming your phone or computer’s processing power and battery) to automatically fine-tune algorithm parameters, making your review schedule increasingly tailored to your unique memory profile.

📝 From Basic to Advanced, Covering All Learning Scenarios

We offer far more than just simple “front-and-back” flipping. Designed around real-world learning and exam requirements, we provide comprehensive question-type support:

Basic Flashcards

Standard Q&A Cards: The classic front-and-back format, ideal for memorizing definitions and concepts.
Cloze Deletion: Hide keywords within a sentence to fill in the blanks based on context, perfect for contextual memory.

Advanced Flashcards

Single & Multiple Choice: Simulates objective exam questions to help you differentiate between confusing distractors.
Multi-Blank Cloze: Supports hiding multiple pieces of key information within a single card, ideal for memorizing complex formulas, legal statutes, or multi-step processes.
Language-Specific Cards: Tailored for language learners, supporting the structural breakdown of words, phrases, and complex sentences with clear audio support to help you break past the “silent language” barrier.
More Types: Offers an even wider array of card formats, which can even be configured for practice exams.

🔒 Privacy & Security

We firmly believe that your learning data and notes belong solely to you. Throughout the card creation and review lifecycle:

Your local notes and card contents are always stored exclusively on your device.
The server-side parameter optimizer only reads anonymized, purely numerical review history (e.g., the day a card was reviewed, and whether the rating was “Remembered” or “Forgotten”). It never touches your actual note text or sensitive content, ensuring your data remains absolutely secure.
