JEE Main and JEE Advanced
AI tutor for JEE from a 1 a.m. doubt to an IIT seat.
Ask a physics, chemistry or maths doubt in English, Hinglish or Hindi, out loud or typed. Niera answers from your own books and shows you the page it used, sets you real JEE papers marked the way the exam marks them, and keeps every question you got wrong coming back until you have it. It is free while it is in beta.
It is 1 a.m. The module skips a step, the teacher is asleep, and the paper is in three days.
Your doubt doesn't have to wait till morning.
- 359JEE past papers, marked the way the exam marks them
- 22,000+practice questions, sorted by chapter
- 669molecules you can turn in 3D
- 32labs that run in the browser
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 module or a past paper and it is read and answered.
- Your booksAdd coaching modules, PDFs and your marked answer sheets. They are used only for you and never shown to another student.
Your book, open at the page.
Niera answers from the books you upload, a coaching module photographed page by page included. A sentence that leans on your book carries a marker. Press it and the page opens with the region the answer used highlighted.
Every answer is labelled with where it came from: your sources, the knowledge base when your books do not cover it, or worked out here when a number is calculated from a formula it cites. A confident guess cannot pass as a fact.
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.
Labs that end in a question.
32 labs run in the browser. The physics practicals go from the simple pendulum to the metre bridge, and the chemistry you can watch goes from Rutherford's gold foil to Le Chatelier's principle.
Run the experiment, change what you like, then answer a question about what you saw. In the one here, hydrogen's electron falls back from n = 4, and the question asks which series the red line at 656 nm belongs to.
Practise on the real exam.
359 past papers, 355 JEE Main sittings and 4 JEE Advanced, open on an exam-style screen with a timer and the question palette, each marked by the scheme its sitting used, negative marks included.
- Full papers, chapter tests, or a paper you describe, such as organic, 30 minutes, past papers only
- In study mode, the AI tutor sits beside each question while you work
- A wrong answer comes back under Revise today until you have got it right twice
Find what is behind the mistake.
A mistake in class 12 electrochemistry often starts in class 11 redox. 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.
Spotting habits under time pressure, such as dropping a sign when the clock is short, is rolling out through the beta.
- 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
Class 11 to IIT, in one place.
Doubts for every chapter of the JEE Main syllabus in physics, chemistry and maths, 359 past papers, more than 22,000 practice questions, 32 labs, and Courses: lectures drawn on a board as they are spoken, in Hinglish, that stop at checks and take your doubt by chat or by voice. The first course is simple harmonic motion for JEE physics.

Questions JEE students ask
01Does it cover JEE Advanced as well as Main?
Yes. You can ask doubts from either syllabus, and the past papers include 355 JEE Main sittings and 4 JEE Advanced.
02Can I ask in Hindi or Hinglish?
Yes, by typing or by talking. Voice works in English, Hinglish and Hindi.
03Can it use my coaching material?
Yes. Photos of a coaching module work, and so do PDFs and your own marked answer sheets. What you upload is used only for you and is never shown to another student.
04How is it different from a doubt-solving app?
A doubt app answers the question you sent. Niera also keeps the questions you got wrong, looks for the idea behind each one, and points your practice at it.
05What does it cost?
Nothing while it is in beta, and no card is asked for. Join the waitlist and your invitation arrives by email when a seat opens.
