Genius’s notes to itself
1Possible slip: using “product = 0” on 7. Not sure yet.
2Move: let her test it. Do not correct it.
3She sees 91 is not 7 and crosses it out herself. Ask what would work.
4After “9”: step back and let her lead.

The same question
“Why does the quadratic formula work?”
AaravKnows the formula, not where it comes from
Genius noticedHe can run the formula but cannot say where it comes from.
GeniusLet us build it together. Take x² + 6x = 7. What number turns the left side into a perfect square?
MeeraFluent with algebra, ready for the full proof
Genius noticedShe handles symbols easily and is ready for the general case.
GeniusWhat is your first move?
RohanGets stuck on squares
Genius noticedExpanding (x + 3)² is shaky, and the formula rests on it.
GeniusBefore the formula, one smaller step. What is (x + 3)² when you expand it?
What it is like to learn with Genius.
A teacher always by your side, who wants you to understand, not just to finish.
Explains first, quizzes later
A new idea starts with a clear explanation and a worked example. Then it is your turn.
Your problem stays yours
On your own practice problem, Genius guides you with questions and hints. Full solutions are for worked examples.
Why it matters, first
Before the maths, a short real-world reason to care. Learning sticks when you know what it is for.
Start where you are
Genius checks the skills a topic rests on as you go. A small gap is fixed on the spot. A bigger one sends you back a lesson.
A different way in
When an explanation is not landing, Genius changes the example, the picture or the size of the step.
See it, do not just read it
Live graphs, figures and neatly written maths, right in the conversation.
Side questions welcome
Ask something off to the side. Genius holds it and comes back to it.
Calm and honest
No empty praise. Genius talks to you like a good mentor: short, warm and direct.
A pause when it gets hard
If you seem very frustrated, Genius slows down and offers support.
The same depth for everyone. A different start for each.
No student is reduced to one score or a label like weak or strong.Genius keeps track of what you have shown it, and changes its mind when you surprise it.
Depth for everyoneEvery student gets the real idea, not a shortcut. A first-timer starts with an explanation and an example. A confident learner starts with the proof and a new problem.
Gaps fixed in placeA small missing skill is taught on the spot. A bigger gap sends you back one lesson first, then returns you to where you were.
Help that fadesGenius steps back as your own work shows you can manage, and comes back when you need it.
- Old ideas, new teacherGenius draws on classical Indian thinking about how knowledge is built and learnt.
- Proof before promisesWe plan to test Genius against other ways of teaching, in a randomised trial with Karnataka students. Until the results are in, we make no claims about what students will learn.
How it is built
AI where it helps. Rules where it must be exact.
Genius uses AI for what only AI can do, and plain rules for everything that has to be right every time.That keeps it trustworthy, easy to check and ready to grow to new subjects.
The AI
- Understands what you wrote, even when it is messy.
- Writes the explanation, the example and the next question.
- Never gives marks and never decides a lesson is complete.
The rules
- Decide what counts as done and what you unlock next.
- Mark your work from rubrics, not from the AI’s opinion.
- Control who can see what.
Teachers write the lessonsSubject experts shape each topic, and every lesson is reviewed before a student sees it.
New subject, new lessonsAdding a subject means adding reviewed lessons. The tutor itself does not have to be rewritten.
The model can changeThe AI model behind the tutor can be swapped for a better one. The rules and the lessons stay the same.
Where Genius starts
Karnataka first, with Grade 10 mathematics.
We start with one syllabus and one subject, and do it well before adding more.
Karnataka SSLCThe first syllabus for Genius, starting with Grade 10 mathematics.
English and KannadaMade for both languages from the start.
Learners, then schoolsWe start with individual learners, then bring in schools and institutions.
