Built a personal knowledge management system demo based on the previous Japanese Kanji manager. It’s something you can store all your ideas, favorite links, notes and manage your projects. It’s a little bit hard to introduce it in several sentences but if you’re interested in notes taking/info managing/daily scheduling/second brain building you can send me a dm for more discussions! Especially I think it would be great for language learning like you can store those minimal semantic units with your own understanding.
