Always good to see more activity in the language learning space. I wish you luck now that you've moved past Anki.

A piece of feedback: one of the common issues I've found with AI-generated questions & answers based on an article is that they will often hone in on testing values. It looks like incontextlearning.com often suffers from this same issue (over half my comprehension questions were "how many"-style). I can easily answer these types of questions even if I don't know what the content is about.
