Stuck on an NCERT doubt? Ask it the way you’d ask a friend.
Teengro answers from the NCERT textbook for your class and subject, so the explanation matches what your teacher and your exam expect.
What you get
- Answers grounded in the NCERT chapter for your class — every Class 11 and 12 Physics, Chemistry and Maths chapter is covered.
- Each formula explained symbol by symbol, with units, and a worked example with real numbers.
- The common mistake students make on that topic, named so you avoid it.
- Photos of textbook questions and PDFs are read and solved.
- Follow-ups like “explain simpler” or “another example” whenever it doesn’t click.
How it works
- Choose your class and subject.
- Type your doubt or send a photo of the question.
- Ask follow-ups until it makes sense.
What an answer looks like
Why does a projectile follow a parabola?
Horizontally nothing acts on it, so x grows steadily: x = (u cos θ)t. Vertically gravity slows it at g, so y = (u sin θ)t − ½gt². Put t = x/(u cos θ) into y and you get y = x tan θ − gx²/(2u² cos²θ) — a quadratic in x, which is a parabola.
Questions
Does it give NCERT exercise answers?
Yes — type the question or send a photo and it solves it step by step. It won’t guess a question from just an exercise number, because numbering differs between NCERT editions.
Which subjects are covered for Class 11 and 12?
Science (Physics, Chemistry, Maths, Biology, Computer Science), Commerce and Humanities subjects from NCERT.
How much does Teengro cost?
You can start free. The Plus plan is ₹49 a month and includes 2,000 Sparks, the credits each question uses. A normal answer costs around 20 Sparks.
Can I send a photo of a question?
Yes. Snap the problem from your book or worksheet and Teengro reads it and solves it step by step. PDFs work too.
Does it answer in Hindi?
Yes. You can pick Hindi or other Indian languages for replies in Settings; formulas and technical terms stay in English.
