CBSE classes 6–12
You deserve more than a one‑shot video. You deserve more than to be one of 25 in a class that moves on without you. Your marks matter to you, so they matter to us. Samajha isn’t a chatbot; it’s the teacher you deserve.

What would happen to the trachea if its cartilage rings were absent, and when would you notice it most?
These lessons are written, not improvised. Each moment, each question, each analogy, curated by people who know that teaching needs planning.
Every great teacher has a whiteboard. Samajha writes definitions, equations and diagrams on a whiteboard, and they stay there afterwards as your notes for that chapter.
You suck at exponents. You’re great at balancing equations. You had a tough week. Square pegs don’t fit in circular holes, so Samajha molds classes around you.
A great tutor knows when your exams are, how you are doing on question types, and how many marks each concept is worth, to decide what to prioritise and what to skip. So does Samajha; it plans your week. Press a button and watch the week rebuild.
What it reads
Not a mock‑up of a promise. The reason under every block is a real field in the database. The scheduler is not permitted to place a class it cannot explain, and a plan with an unexplained block is rejected before anyone ever sees it.
First
Around school, around cricket, around dinner.
Then
Teaching, practice, doubt sessions, practice exams. You never choose the topic.
An hour before
We hold you accountable.
And if you skip it
Our algorithm self‑corrects to maximise your marks.

Lines of syllabus
Every topic and subtopic of your board, entered by hand with its exam weighting and what it depends on.
Anyone can point a chatbot at a syllabus and have every board and every subject by the evening. An ocean an inch deep. We would rather go a mile down on fewer things.
Everyone else
Every board, every subject. An afternoon per class.
Samajha
One board, maths and the sciences. Weeks per chapter.
So: CBSE, classes 6 to 12, maths and the sciences, chapter by chapter. English, Hindi, Social Science and Computer Science are being written, in the order our families ask for them.
what about my board?
If it is not on this list we have not written it yet. Message us and we will tell you where it sits in the queue.
You are not buying explanations. You already know your child can look up an explanation. You are buying what a good tuition teacher actually sells: someone else decides what gets studied, someone else notices when it does not, and it is no longer your job to ask at nine o’clock whether the homework is done.
You get your own account, not a second job. A place to look when you want to look, and peace of mind when you do not.
so I have to check a dashboard now?
No. That would just be your old job with a nicer screen. The point is that the chasing has an owner, and it is not you. Look when you feel like looking.
Which classes she attended, and which she did not.
The exact chapters and subtopics covered, not “worked on Physics”.
Homework set against homework done.
What she is weak at, before the exam finds it.
Whether she is on pace to finish the syllabus in time, and by how much she is not.
A question box. Ask “how is she doing in chemistry?” and get an answer.
Not her transcripts. What she tells the tutor when she is struggling stays between her and the tutor. A child who knows every word goes home stops telling the truth, and a tutor who is not told the truth cannot teach.

That is the right question, and it is why there is a time and a reminder rather than an icon on a phone. Five free classes so you can find out before you pay anything. If she does not turn up for them, do not pay us.
No. That is the entire product. If you still have to sit there, we have failed and you should get your money back, which you can, within ten days.
ChatGPT answers the question she asks. It does not decide what she should be studying in August, notice that she has not opened trigonometry, set her homework, mark it, or turn her three wrong answers into Wednesday’s class. You are not buying answers. You are buying a teacher.
Her classes are hers. We use them to teach her better and for nothing else. Parents cannot read her transcripts, and that restriction is enforced in the code rather than in a policy document.
Full refund within ten days of a billing month, no conversation required. Cancel from the account page. You never have to phone anyone to stop paying us.
