THETAS.AI

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

ThetasAI is a private learning feed built on your learning brain: what you know, concept by concept. Home shows what moves you forward today, from your tutor’s lesson notes and homework to questions on your weak spots. Learn with Theta, your assistant, and the Thetas tutor, or connect your own AI to it.

ThetasAI is in closed beta, starting with IB Maths AA SL and HL students, so students join by invitation. Have a code from your school, centre or tutor? Join with it and you are in straight away.

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.

Your weeks, planned to the exam.

Open the app and you know what to do today. If you are in a class, your teacher’s focus sets the starting point, and Theta, your assistant, can change your plan when you ask.

Lessons you talk through.

A live lesson with a whiteboard your tutor draws on. Type, or talk it through if you prefer. It is prepared before you start, with diagrams and pictures found for your own course. 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

    The Feed is short questions and flashcards, one swipe at a time. Every answer goes back into your learning brain, and the next question comes out of it. Stuck? Ask Theta about the question, or send a photo of your working.

    Questions

    What is ThetasAI?

    ThetasAI is a private learning feed built on your learning brain: a record of what you know, concept by concept, from your lessons, practice and tests. Home shows what to do today, including your tutor's lesson notes and homework. Around it sit a study plan to your exam, the Feed, Test mode and a workspace of notes, questions and flashcards. You learn with Theta, your assistant, and the Thetas tutor, or connect your own AI to it.

    How is it different from using ChatGPT or Claude on their own?

    A general AI does not know what you know. ThetasAI does, from evidence: answers marked against the mark scheme, explanations you gave, checks over time. Its tutor gives you a hint instead of the answer, and when you connect your own AI it can read your learning brain too.

    Which courses does it cover?

    It is built first for IB Maths Analysis and Approaches, SL and HL: the full syllabus, a question bank and study plans to the May exams. Other courses, including IB Maths AI, IGCSE Maths, some HKDSE subjects and IELTS, have their syllabus in place with less practice material so far. You can also add your own course from your slides and papers.

    Can I connect my own AI?

    Yes, in beta. Make a token in Profile and settings, Connect your AI, and add ThetasAI to Claude Code, Claude Desktop, Cursor or another app that supports MCP. It can read your learning brain and make notes, questions, flashcards, lessons and board slides in your workspace. It cannot mark you as knowing something. The docs are at thetas.ai/developers.

    How much does it cost?

    Free for students during the closed beta, by invitation or with a code from your school, centre or tutor. The advanced tutor is part of Pro, with two lessons to try it. Schools, centres and tutors get a quotation.
