open-spaced-repetition/fsrs4anki
A modern Anki custom scheduling based on Free Spaced Repetition Scheduler algorithm
Comprises a dual-component system: a scheduler that replaces Anki's built-in algorithm with FSRS-based card sequencing, and an ML-powered optimizer that analyzes review history to fine-tune scheduling parameters to individual memory patterns. Natively integrated into Anki 23.10+, with backward compatibility via standalone addon; carefully curated add-on compatibility matrix to prevent interval-modification conflicts.
