AI Tutors: How do we ensure they teach, not just "solve"?

We are launching Owlvera SAT Prep in less than 2 days! As we fine-tuned "Nester" (our AI tutor), our biggest obsession was making sure he doesn't just hand out answers but actually teaches the underlying concepts—like a human tutor would.

I’d love to hear from this community: What is the #1 feature or trait you look for in an AI educational tool? Do you prefer Socratic questioning or direct explanations?
