NCERT class 11 and 12
AI tutor for NCERT where every IIT and AIIMS story starts.
Ask a doubt from any NCERT chapter in physics, chemistry, maths or biology, in English, Hinglish or Hindi. Niera answers from your own books and notes, NCERT included once you add it, and opens the page each answer used. It is free while it is in beta.
It is 1 a.m. You have read the same NCERT line six times, it still does not make sense, and the unit test is tomorrow.
Your doubt doesn't have to wait till morning.
- 4subjects: physics, chemistry, maths and biology
- 3languages you can talk in, Hinglish included
- 1,372ideas on the chemistry concept map
- 32labs that run in the browser
Every answer says where it came from.
A sentence drawn from your own books or notes is marked as coming from your sources, and it opens the page it leaned on. Add the NCERT books as PDFs or photos and they count as yours.
When your books do not cover the question, the answer is marked as coming from the knowledge base, and a number calculated from a formula the answer cites is marked as worked out here. The labels stay visible, so you can always tell your own book from anything else.
See it drawn.
Organic mechanisms are drawn arrow by arrow inside the answer, and you can scrub through the steps back and forth. A molecule named in the answer opens in 3D, and 669 of them are ready to turn with a finger.
When a chapter will not make sense.
The trouble is often in an earlier chapter. Niera's chemistry concept map links 1,372 ideas through 1,222 prerequisites, so a wrong answer can be traced to the idea it rests on, and your next steps on Home point at that chapter. The three steps here are one path through it.
Chemistry notes are written topic by topic, and each opens with the questions you got wrong before, with the AI tutor beside the page.
- The mistakeTaking n from one half-reaction in ΔG = -nFE, so ΔG and K come out wrong by a whole-number factor
- What it rests onBalancing by half-reactions until the electrons cancel, from redox reactions in class 11
- Where that comes fromTelling which species is oxidised and which is reduced
Ask it out loud.
Say the doubt the way it comes out. The call already knows your class, your exam and the subjects you take, so you never start from zero.
- VoiceTalk in English, Hinglish or Hindi, or type if the house is asleep.
- PhotoPhotograph a question from your book or a test paper and it is read and answered.
- Your booksAdd NCERT, coaching modules, PDFs and your marked answer sheets. They are used only for you and never shown to another student.
