THETAS.AI

AI knows what to teach.
We tell it who you are.

ThetasAI gives every student a learning brain: what you know, concept by concept, built from everything you do. Your AI tutor teaches from it, with a hint instead of the answer.

Your learning brain.

Behind every lesson and question sits a profile of you that keeps growing: what you know, how well, and what is slipping. It is how ThetasAI knows who it is teaching.

A live voice lesson with a whiteboard your tutor draws on. It asks for your first step, gives a hint when you are stuck, and marks your answer against the mark scheme. Here is one, replayed.

    Hints, not answers.

    In a randomised study of about a thousand high school maths students, those who practised with plain ChatGPT did 48% better in practice and 17% worse in the exam. So when you are stuck, ThetasAI gives you the next small step and leaves the working to you. Bastani et al., PNAS, 2025
