Anki's scheduler is better. That is not the question
It is worth saying plainly: for long-term retention of a mature deck, Anki's spaced repetition is the strongest thing available and NoteLinkAI does not claim to beat it. Med students who have maintained a deck for two years are getting real value from an algorithm tuned over a decade, and no auto-generated alternative changes that. The question a student actually faces is different. It is not 'which scheduler is better', it is 'will the deck exist at all', and for most people carrying five courses the honest answer over a full term is no.
