Most AI tutors are a chat box: you ask, it answers, and nobody can say what was learned.
Skolvio is a course. Grades 4-8 Math, English, Science, where every question is tagged to a concept, so mastery is measured rather than guessed at.
That's what keeps humans in the loop. Parents get a weekly report whose numbers are computed, never AI-generated. And a child's own tutor plugs in free: sees the shaky concepts, assigns the next lesson, reports to you under their own name.
