Gnosis is a spaced repetition system-like that enhances memory retention through active recall. It employs a Q&A format, where each gnosis consists of a question, answer, and explanation. Gnosis algorithm is highly adjustable, allowing users to set specific values not just for note decks but for tags as well. Gnosis' adjustability allows users to fine-tune settings not only for entire note collections but also for specific tagged topics, thereby creating a personalized learning environment for each topic.
