This is great, I just went through the first lesson. As someone trying to learn Spanish I have been putting off getting Claude to write a short story for me daily, but this is better with the repeated repetition and built in translate/clues.

I wish you could highlight multiple words to translate them though, because sometimes it's not just one word that gives the meaning, but the combination.

Might be nice to make the quiz easier to find on the main page. It took me some scrolling and looking before I saw it, and, and maybe make it accessible without creating a user account. I'd definitely do the free quiz, but seeing a sign in screen so early on is kind of off putting.
