The biggest difference isn't a feature — it's philosophy. Khanmigo is deliberately Socratic: rather than give the answer, it nudges the student with questions until they get there. That's excellent for building independence, and it's a considered design choice by Khan Academy.
But when a child is genuinely stuck — the night before a test, or on a concept they've never seen — many families want the concept taught, clearly and completely. That's what Reva does. It works the problem on a live whiteboard, narrates each step by voice, ties it back to the underlying concept, then sets targeted practice so the method sticks. Your child can interrupt and ask "why?" at any point, and Reva explains again a different way.
