CBSE Grade 8 · ScienceLive now · limited free pilot

The tutor that doesn't give up until you  get it.

Tattvik meets your child where they are and never runs out of energy or ideas. However long it takes, it finds another way in: a fresh angle, a new analogy, a worked example, until it clicks. Guided revision, graded practice and exam prep, concept by concept.

Grade 8 Science is live today. More grades and subjects are coming — register to get early access. Teaching a class? See Tattvik on your smart board.

Inside a lesson

One small idea at a time — seen, moved, tried and checked.

Every Grade 8 Science lesson is built from a few short ideas. Each idea comes with a picture, most with something to do, and the lesson ends with questions that show the idea has stuck.

Heat makes the particles move more

Warm a block of ice and its particles vibrate harder. Keep heating and they break out of their places, then slide past each other, then fly apart.

One small idea at a time

A lesson is a few short ideas, not a wall of text. Each one has its own picture and its own example.

Pictures they can move

Moving visuals play stage by stage, then hand over the slider — warm the ice and watch what the particles do.

A path they can see

The revision path shows every step and the one they are on, so a session has a clear end.

Lessons that connect

Connections lists what this lesson builds on and leads to. One tap looks back at an earlier idea, then returns.

A task after the idea

They don't just read it. They sort it, match it, label it.

A quick task follows an idea, so a child uses it while it is fresh. If they are stuck, Help with this gives a clue that points the right way — then one more try before the answer is shown.

The checks that finish a lesson

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. A concept is revised only when every check question is answered with real understanding.

Check 1 of 2Why does a drop of ink slowly colour a whole glass of still water?
Your answerBecause we stirred it?
A different 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.

Our teaching approach

Understanding where your child is stuck changes how we teach.

A wrong answer is information. We read what it shows, then choose the help that fits it.

01Listen to the child’s answer02Understand the difficulty03Give focused help04Check understanding again
An idea misunderstoodExplain it from a different angle

Two tricky tasks in a rowSlow down: explain it more simply, look back, or take a short break
Looking back: Particles of matterBack to my lesson

Look back opens the earlier lesson's idea and one small task, then returns to the same step — so a gap gets filled without losing the place.

The same care. Different ways of teaching each subject.

Ways to learn

Built for how your child learns — not the other way around.

Languages

Read it in their language

English is the main learning language. Lessons can be read in हिन्दी, தமிழ் or ಕನ್ನಡ, and tapping an underlined key word shows what it means. Questions and answers stay in English, the way the exam will be.

Reading & speaking

Listen, or dictate a reply

Press Listen and the card is read aloud, each part highlighted as it is read, in a voice and speed they choose. Children can also dictate an English reply, check the transcription, then send it. Dictation needs microphone access and a supported browser.

Their pace

A pace they choose

Tattvik suggests a weekly pace from their study days and time; your child adjusts and confirms it. Classroom coverage informs revision but doesn't by itself mark them behind — and the plan has no peer rankings.

Ask Tattvik

Type what they want, and go there

Ask in ordinary words — "show me my schedule" — and open the matching page. Ask Tattvik is typed navigation, separate from the tutor chat.

Tools

A cheat sheet and a scratchpad

Every topic has a one-page cheat sheet to print for quick revision. The scratchpad for rough work stays on their device — the tutor doesn't read or mark it.

For the curious

Lessons beyond the textbook

Extra Science lessons sit below the chapters for children who want more. They are optional: never planned, never due, and never counted against the syllabus.

The weekly plan

Their pace, a steady plan, and a clear line to the syllabus.

Your child sets a weekly pace they can keep, and Tattvik turns it into one steady week of goals — what school has set, what you have set, what comes next, and what is starting to fade. Progress is measured against their own plan, not the class.

Assessment that teaches

A test isn't the verdict. It's the next lesson.

Marks earned — with partial credit where it's awarded — and performance topic by topic, with Strong, OK and Weak tags that name what to revise. Review the questions, model answers and feedback, then revise weak topics and try again.

Quick Test starts straight away; a planned practice exam lets them prepare towards a date. Both use timed practice papers. A test can come from your child, from you, or from their teacher — and each one shows in their list marked with who set it.

The pilot

Free, for good — for a limited pilot. Starting with CBSE Grade 8 Science.

We're taking a limited number of pilot sign-ups — join now and Tattvik stays free for your family, permanently. More grades and subjects are coming; sign up and we'll open them to you first.

For schools & teachers

Your smart boards are ready. Now the lessons are too.

Schools have put a smart board in every classroom — and teachers are still left to make the content and load it into an LMS before they can use it. Tattvik is plug and play: open the topic on your teaching board and the whole lesson is there, so a teacher can give the period to teaching.

Nothing to prepare

No slides to build, no content to upload, no LMS to set up. Every lesson arrives ready and reviewed: the ideas, the pictures, the moving visuals, worked examples, tasks, questions and a summary.

Plug and play on your board

It runs in the browser on the interactive panel or projector your classrooms already have. Sign in on the board, open the topic, tap Teach — and you are teaching in minutes.

Your attention stays on the class

The teacher sets the pace with Back and Next, or a clicker. Play reads each idea aloud and stops where the class must think, so the teacher teaches the room rather than operating a screen.

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. Lessons are built from small ideas, each with a picture — many of them pictures your child can move — and a quick task to try. 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. On a task inside a lesson, Help with this gives a clue that points the right way, then one more try. If a couple of tasks in a row are hard, it offers to slow down: explain the idea more simply, look back at the earlier lesson it builds on, or take a short break. On the questions that finish a lesson, 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.

Is the tutor an AI — and can it be wrong?

Yes, and it says so. At the start of a lesson Tattvik tells your child that it is an AI tutor and can make mistakes — and to ask about anything that looks wrong, or tell a teacher or parent. The lessons themselves are written and approved in advance, not made up on the spot; what is generated live is the tutor's reply to your child's own answer.

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, தமிழ் or ಕನ್ನಡ?

Tattvik teaches in English. Lessons can also be read in हिन्दी, தமிழ் or ಕನ್ನಡ to help an idea land, and tapping an underlined key word shows what it means — 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 weekly report shows the days they signed in, the concepts they learnt and the topics they revised, alongside progress against their own plan. You can also set a test on any topics and see their score and their answers.

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. Teach the lesson from your smart board, finish the topic, and it opens 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 work on our smart boards?

Yes — it is plug and play. The Teaching screen runs in the browser on the interactive panel or projector your classrooms already have, so there is nothing to install. A teacher signs in on the board, opens the topic and taps Teach. The lesson fills the board as large cards the teacher steps through with Back and Next, or a clicker.

What do teachers have to prepare?

Nothing. Schools have smart boards, but teachers are usually still left to make the content and load it into an LMS. Tattvik arrives with the lesson ready — the ideas, the pictures and moving visuals, worked examples, tasks with their answers, and a short re-teach for each common mix-up. A teacher can start teaching in minutes and give the period to the class rather than to setting up a screen.

Can teachers set tests and question papers?

Yes. A teacher can set a dated test for a class— choose the class, the topics and the day. Students get a plan to prepare and a practice paper, and the teacher sees each student's topics revised, papers taken, best score and answers. For printed exams, one click drafts a full question paper from the exam's setup; add or remove questions, then download it as a Word file to finish offline.

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. For a demo, write to contact@tattvik.ai — a live session, the class reporting, and how onboarding works.
