Very cool! I made something similar a while ago for learning Mandarin Chinese. Unfortunately more basic than your Spanish version: https://dailychinesestories.com.
I miss working on language learning tools. My attempts were all in the ~2024 era of LLMs.
Thanks! And you're website looks pretty cool.
You should try working on language learning tools again. The models now are pretty good especially since you don't always need the frontier model to generate good stories. I would love for this project to get solid traction so I could distill my own models that are better at meeting my story creation requirements.
