Yuhimo's answer
Yuhimo started from my own experience preparing for exams and learning programming topics. I often needed to understand concepts, systems, and how different processes fit together — not just memorize isolated facts or definitions.
Traditional flashcard workflows did not fit that well. I wanted to keep notes of different sizes, from short concepts to larger explanations, and use those pages themselves as units of learning instead of creating thousands of separate cards for every fact.
That idea became Yuhimo: a notes-first learning system where you can organize knowledge, choose which pages are worth remembering, and review them over time using spaced repetition. During each review, the user evaluates how well they remembered the page, and Yuhimo’s internal scheduling algorithm uses those ratings to calculate when that page should be reviewed again.
The goal was to combine understanding, note-taking, and long-term retention in one system without forcing complex subjects into hundreds or thousands of isolated flashcards.
