Picture a learner with a tireless guide at their side. One that answers any question without judgement, explains a tricky idea in three different ways until it lands, follows curiosity wherever it leads, and never runs out of patience. Picture what that could mean for a student in a classroom with too few teachers, for an adult finally opening a subject they thought was out of reach, or for a child who asks the questions no one ever has time to answer.
That is what AI in learning could one day unlock: a world where no learner is left alone with a question, and no subject is too big to step into. It is a possibility we take seriously, and it is the promise we want to build toward.
The early evidence is encouraging. A 2025 meta-analysis of 228 studies found large positive effects of AI on cognition, with generative AI showing the largest effects among AI types.1
Dr. Ying Xu's experimental work at the Harvard Graduate School of Education has repeatedly shown that children who dialogue with a well-designed AI character comprehend stories better and learn more science vocabulary than children without it, in some contexts with gains comparable to human partners.2 The biggest beneficiaries are often children with the least access to a knowledgeable conversation partner at home.
Taken together, the positive evidence points to a consistent pattern: tightly scoped content, supervision by a trusted adult, and AI used to deepen human learning rather than replace it. That is the shape of the promise as we understand it today, and it is the pattern every AI-driven experience we build is designed to support.
