We’re developing tools that connect instructional evidence across sessions, suggest relevant practice, and help an educator prepare with a clearer picture of the student’s recent learning.

Educator-led tutoring is our established service. AI-supported preparation, personalized problems, and feedback workflows are under internal evaluation, rather than generally available family features.
