  "Description": "R bindings for the fsrs-rs Rust library implementing the\nFree Spaced Repetition Scheduler (FSRS) algorithm. FSRS is a\nmodern spaced repetition algorithm based on the DSR\n(Difficulty, Stability, Retrievability) model of memory.\nIncludes parameter optimization to train custom parameters from\nyour review history, achieving better scheduling accuracy than\ndefault parameters or traditional algorithms like SM-2.",
