How Khan Academy can use Orb Platform

Verified vocabulary infrastructure for Khanmigo

The Scenario

Khanmigo, Khan Academy’s GPT-4 Socratic tutor, guides a 7th grader through world history. The student encounters “civilization.” Instead of generating a definition that might be wrong or off-level, Khanmigo fetches a verified, age-calibrated definition from Orb Platform — then a structured lesson to teach the word in historical context, and a quiz to verify the student understood. The fact base is deterministic. The Socratic interaction is Khanmigo’s job.
