What it is

Synthesis Tutor teaches the K–5 maths curriculum and beyond through interactive lessons with digital manipulatives. Micro-assessments in every lesson check understanding, and children move on only once they show mastery; flashcards adjust difficulty in real time. Synthesis says it uses AI where appropriate alongside educator-designed lessons, and it is not an open chatbot.

What the AI does

Interactive digital tutor with step-by-step guidance
Micro-assessments that move children on only after mastery
Adaptive flashcards that adjust difficulty in real time
Read-aloud and adjustable voice speed for younger children

Pros and cons

Mastery-based lessons rather than just practice drills
Structured tutor, not an open chatbot
Family plan covers up to seven children
Works on iPad, Android tablets and computers, including Chromebooks

Expensive monthly; best value only on the annual family plan
Maths only, and the iOS app runs on iPad, not iPhone
Outcome claims rest on testimonials; no independent privacy certification named
