I tried out a bunch, including Babbel, Busuu, Language Transfer, Mango, and Memrise. I didn’t like them for one reason or another. I finally landed on Lingodeer. It’s similar to Duolingo, but it is a paid app. (You can try level 1 of any language for free.)

The regular subscription price is definitely not worth it. It’s okay (not great, but not awful) when they do their sales. But I felt okay about paying human workers.

This kind of learning is a great start, but will only get you so far. If your local library has access to Kanopy, look for the Great Courses series on Spanish. I thought that was an excellent series after a little bit of Duolingo.

Duolingo got me enough vocabulary in Spanish to put the simplest sentences together, and then follow more robust lessons. I still think it was a good starting point, but I won’t use it anymore on principle.

I had to tell a bunch of librarians that LLMs are literally language models made to mimic language patterns, and are not made to be factually correct. They understood it when I put it that way, but librarians are supposed to be “information professionals”. If they, as a slightly better trained subset of the general public, don’t know that, the general public has no hope of knowing that.
