I tried the best I can to test specially Japanese and Chinese without speaking those languages myself.
the app uses real human content (audio and text) for the most part, so hopefully it comes natural enough. there is still some AI though
I have been using Babbel, and while it's nice to have mini lesson to take each day... they offer no option to write out notes, or to look at the grammar and get some context, no extra examples and flashcard system is just awful.
I really enjoy the concept behind the app focusing on subjects rather than structured lessons. I enjoy going on learning rabbit holes so this would fit me better than structured lessons.
Lastly a video or demo of the app would help as the UI is quite complex. It's not clear how I would go from importing a web page to using the cards for example.
Feel free to ping me if you have updates - happy to help support another indie dev!
I am the opposite, I always prefer local/offline if there is the option, I use 0 web apps.
On the video, yes, I totally need a video.
Good luck to you as well!
I'm not really sure what to do with this -- I thought you wanted someone to take a look at some Japanese content, but I can't find any in the app/tutorial.
