Yuhimo

Yuhimo combines lightweight note-taking with optional learning and spaced repetition. Notes are organized as pages in a tree, and any page can be added to learning without converting it into flashcards. During review sessions, users can use questions and answers for active recall, reveal the original note, rate how well they remembered the material, and let Yuhimo schedule the next recommended review. Yuhimo also includes AI-assisted tools for generating questions and creating draft study material from a topic, pasted text, PDF, or DOCX. Generated material can be reviewed and edited before it is saved to the user's notes. Other features include scoped learning sessions, import and export, backups, reminders, offline read-only access, learning statistics, and light and dark themes. The product is designed for students, self-learners, developers, and anyone who wants to keep useful knowledge organized while selectively reviewing what they want to remember long term.
