Yuhimo is a lightweight notes and learning app for people who want to keep useful knowledge and actually remember it.
Create normal notes and organize them into a knowledge tree. When something is worth remembering, add that page to learning. Yuhimo schedules future reviews using spaced repetition, while you assess your own recall with Forgot, Barely, Remembered, or Easily.
Unlike flashcard-first tools, Yuhimo lets you learn entire notes and topics without converting everything into isolated cards.
You can also use AI to generate questions for existing notes or create draft study material from a topic, pasted text, PDF, or DOCX. You stay in control of the material and decide what is worth learning.
