Wanted to use AI to give feedback on the answers, any tips?

I want to make a deck with the front being the word, and you have an input to make up a sentence with it, conjugate it if necessary, and on the back call OpenAI API to judge how good it is.

Does this sound like a good idea?

Any tips to make this work?

Is there something like “env vars” on the Anki deck to store the API key if I were to share the deck?
