Hey Product Hunt! 👋

I'm the solo developer behind Yuhimo.

I built Yuhimo around a simple problem: saving notes is easy, but actually remembering what you've learned is much harder.

Most note-taking apps focus on storing information, while spaced repetition tools often expect you to turn everything into flashcards. I wanted something in between.

With Yuhimo, you can:

Organize your knowledge in regular notes and nested pages.
Choose which pages you actually want to remember.
Review them through spaced repetition and active recall.
Generate editable study materials from a topic, text, or PDF.

The idea is simple: not everything you save needs to be memorized. But for the things that matter, Yuhimo helps you come back at the right time.

I'd especially love feedback on the learning workflow. Would you find reviewing entire notes more useful than creating individual flashcards?

Thanks for checking it out!
