What students actually ask

Every one of these is a real question against a chapter that exists. Open one to see the shape of an answer before you type your own.

Questions about the tutor

Is it free? Do I need an account?

Yes, it’s free. Searching and reading any answer already on the site never needs an account. Your first new question is free too — after that, logging in (also free) lets you keep asking and see your answer attributed to you.

Where do the answers come from?

The tutor first searches the NCERT chapters for your class and subject, so the rule and the definition match your book, and it links the chapters it used. Then it adds what a good teacher would: the story behind the idea, real-life examples, pictures and a quick self-check.

Are the answers saved?

Yes. Every good answer becomes its own page, so the next student who asks the same thing gets it instantly, and you can share the link. The newest answers are on this page; all of them are at "See all answers". Questions with personal details are never published.

What if my question is not in NCERT?

You still get an answer, but it is labelled "General knowledge" instead of "From NCERT", so you always know whether the book backed it up.

Which classes and subjects are covered?

Class 1 to 12, every NCERT subject — Maths, Science, Physics, Chemistry, Biology, Social Science, English, Hindi, EVS, Computer Science, Accountancy and Business Studies.

Can I ask in Hindi?

Yes. Ask in Hindi and the answer comes back in Hindi. Every chapter page also carries notes in both languages.
