In the revision

A wrong answer never gets the solution. It gets a better explanation.

Tattvik finds the exact misconception and explains it a different way — an analogy, a worked example, a step-by-step — and asks again. The concept is only mastered once every checkpoint is genuinely understood.

C2 / 4Diffusion
ConceptDiffusion is just particles spreading from where they're crowded to where there's room — like the smell of food drifting across a kitchen.
QuestionSo why does a drop of ink slowly colour a whole glass of still water?
Your answerBecause we stirred it?
A better explanationNo stirring needed — that's the surprising part. The ink particles move on their own, from the crowded drop into the empty water, until it's even. So: why does the colour spread without stirring?
Your answerThe particles spread out by themselves until they're evenly mixed.
Mastered ✓Exactly. That's diffusion — locked in.

The exam practice

Sit the whole paper — timed — before the real one.

When the topics are revised, Tattvik builds a full practice exam from the question bank — questions spanning every chapter, a running clock, flag-and-return, and a question map. The dress rehearsal for exam day, as many times as you want.

After the paper

See exactly where you stand — and what to revise next.

Not a bare score. Tattvik breaks the paper down topic by topic across every chapter, names the ones dragging you down, and points you straight back to revise them — while there's still time before the exam.

Questions

The things people ask us first.

Straight answers on how Tattvik teaches, what it costs, and how we treat your child's data.

For parents

What is Tattvik?

A personal AI tutor for Grades 8–12 that does at home what a good teacher does in class — only one-to-one, with unlimited patience. It follows exactly what school is teaching: the same board, the same syllabus, the same chapter, at the same point in the term. It re-explains each concept as many times, in as many ways, as your child needs, and checks through practice that it genuinely stuck before moving on. The pilot is live today for CBSE Grade 8 Science; more grades and subjects follow.

What happens when my child gets stuck?

Tattvik doesn't hand over the answer. It explains the idea a different way — a new analogy, a worked example — and asks again. Only after three genuine attempts does it walk through the answer properly, and then it asks a fresh question on the same idea. A concept counts as mastered only when your child gets there themselves.

How is this different from ChatGPT?

Most chatbots will scaffold an answer if you ask them to — that isn't the difference. Tattvik teaches to a method, on your child's actual syllabus, and it remembers. It follows your board's sequence and what the class has already been taught, keeps a running picture of which concepts are solid and which are shaky, and comes back to the weak ones day after day. A chat session ends and forgets; this is the same tutor every evening, still holding the thread.

Will it just give my child the answers to homework?

No. Bring it schoolwork and it behaves like a tutor, not an answer key — it won't write the essay, and it guides your child to their own answer. You can also turn on a stricter mode if you'd rather it held the line harder.

Does it work in हिन्दी or தமிழ்?

Tattvik teaches in English. Where a concept has been translated, your child can flip the explanation into हिन्दी or தமிழ் to help it land — questions and answers stay in English, the way the exam will be.

Why does the pilot start with Grade 8 Science, CBSE?

On purpose. We'd rather get one subject genuinely right — taught properly, measured honestly — than list thirty on a landing page. More grades and subjects follow once this one has earned them.

What does it cost?

Nothing, permanently. Families who join during the pilot keep Tattvik free for good — not a trial, not a year. We're keeping the pilot deliberately small: it's the number of families a small team can support well.

How do I know if it's helping?

You can see what your child is working on and where they're getting stuck — without having to sit beside them every evening. Your parent dashboard carries a weekly read: days studied, concepts learnt, which subjects are on track, and the one topic worth a gentle nudge this week. No grades to decode, no panic.

Is my child's data safe?

This is where we're strictest. Data is encrypted in transit, access is locked down by role, and we keep only what we need — old data is deleted once its retention window is up. We ask a parent to consent before your child gets going and record it with real proof: the exact policy version accepted, by whom, and when. You can withdraw that consent and have your child's data erased. We don't show ads, and we never sell data.

What do I need to get started?

A browser on a phone or computer — there's nothing to install. Sign up at app.tattvik.ai; it takes a few minutes. The pilot is open in India for now.

For schools & teachers

How does Tattvik work with schools?

It follows exactly what you're teaching — the same board, the same syllabus, the same chapter, at the same point in the term. It isn't a parallel course competing with your classroom for a child's attention: it picks up where the lesson left off. Teachers mark topics as taught; those open for revision with the tutor, concept by concept, consolidated with timed practice papers. And every child in the class gets the same tutor — the same patience, the same attention, for all of them.

Does it replace teachers?

No — it reinforces them, and the loop runs both ways. What you teach in class gets reinforced at home, instead of the two pulling in different directions: Tattvik gives every child the personal teaching a full classroom can't — meeting each student where they are, re-explaining as many times and in as many ways as it takes, on the topics you've actually taught, until it holds. And what a child struggles with at home comes back to you as a signal, not a judgement: this concept didn't land, and here is where — so you can address it in the next lesson instead of discovering it at the next test.

What visibility do we get into student progress?

Concept-level signal, not surveillance. Teachers see which ideas the class is finding difficult — the misconceptions several students share, the ones worth reteaching to the whole room — and where each student stands, topic by topic. It's built from real revision and practice, not scores alone, and it is not a record of every conversation a child has with the tutor. Leadership sees the same picture rolled up across classes.

How do you handle student data and consent?

Deliberately conservatively. Encryption in transit, role-based access control, and retention windows that prune data on a schedule. We ask for parental consent at sign-up and record it verifiably — the policy version, the guardian, the timestamp — and log erasure when consent is withdrawn. No ads inside the product, and we never share your child's personal or learning data with third parties — we measure our own ad performance without sharing your data. We're happy to walk your data-protection lead through the details.

What does it cost for schools?

Start with a free three-month trial — run it with real classes, no commitment. What it costs after that depends on what you need: how many grades, which subjects, how you want to roll it out. We'll work that out with you.

How do we get started?

Your school can be live in five minutes. No implementation project, no customisation phase, no advance or implementation payments — that era is over. Sign up, and you're ready to support your students on the free three-month trial. Run it with real classes — no commitment, no payment — then decide. It's as easy as setting up Gmail for your organisation, and it's the same five minutes whether you start from a demo or sign up directly.
