The AI tutor that
teaches children to think
Spark is a personal AI tutor that guides children through problems with questions and hints — never by giving answers. Real understanding, not just completed homework.
Meet Spark
A personal AI tutor for children ages 7–14. Instead of giving answers, Spark asks the right questions — helping children discover solutions themselves. Built on Claude by Anthropic, the safest AI available.
