Master FSRS-6 Spaced Repetition & 6 Interactive Study Modes
Combine algorithmic memory scheduling with active recall, handwriting practice, audio immersion, and customizable quiz settings.
FSRS-6 Smart Review (Spaced Repetition)
Powered by the Free Spaced Repetition Scheduler (FSRS-6), Smart Review models each card's Memory Stability (S), Difficulty (D), and Retrievability (R). Rate your recall after flipping each card (Again, Hard, Good, Easy) to schedule your next review right before you would forget.
Basic Flashcard Review (Flip Mode)
Flip through your deck at your own pace with keyboard shortcuts (Space to
flip, arrow keys or 1–4 to grade), star difficult cards for targeted cram
sessions, and toggle front/back orientation.
Writing Review (Typed Recall)
Type the exact answer from memory before seeing the back of the card. Ideal for foreign language spelling, technical terminology, statutory citations, and chemical or mathematical formulas.
Audio Review (Listening Mode)
Listen to terms and definitions spoken aloud sequentially with configurable pauses and playback speeds—perfect for commuting, walking, or auditory pronunciation drills.
Drawing & Handwriting Canvas
Practice stroke order and visual recall on an interactive scratchpad before revealing the answer—built for Japanese Kanji, Chinese Hanzi, Korean Hangul, Arabic script, and structural diagrams.
