Carolie Renée asked: I am looking for good apps, ideally not linked to google, open source and ethical would be fantastic as well... Only thing though, the app has to have a good UX/UI and not appears like it is an old app. The languages I want to learn, for now, are Spanish (I am not a beginner anymore, but I still have to improve) and Korean.

And I answered: if i had a lot of spare time, i would write a community website where people would register and say their language(s), and then they (or other users) would start collecting small texts in that language, and every text would become a lesson, with vocabulary entries. And all that data would be free for everybody to use. Money would come from subsidies or from premium users. You, Coralie, might help me as a tester. I suggest that we make a brainstorming video meeting in ca 2 weeks. Time for me to finish my current project and time for you to maybe find some existing solution.
