Your books, your notes
AI tutor that answers from your own books even the module with your pencil marks in it.
Photograph your coaching module, upload a PDF, or add your own marked answer sheet. Niera answers your doubts from those pages and opens the region each answer used, so you can read it in the book's own words. It is free while it is in beta.
It is 1 a.m. The answer is somewhere in the 400-page module, and you cannot remember which chapter.
Ask, and it opens at the page.

What you can add.
A photographed page is read once and kept as a page you can cite, the picture included. You can ask about one line or about the whole file: a doubt about a single step works, and so does asking what a chapter of your module covers.
- PhotosPrinted pages from a module, a guide or a worksheet.
- PDFsA whole PDF of up to 200 MB, NCERT included.
- Marked sheetsA test you got back with the teacher's marks on it.
Press the marker, see the page.
A sentence that leans on your book carries a small marker. Press it and the page opens with the region the answer used highlighted, so a wrong reading of your book is something you can see and catch.
When your books do not cover the question, the answer comes from the knowledge base and is labelled that way, never passed off as your book.

Yours alone.
What you upload is used only for you.
- Never shownNothing you add is ever shown to another student.
- Never pooledIt is never pooled into a shared library.
- Never matchedIt is never matched against anyone else's copy of the same book.
Questions people ask
01Do I have to upload my books?
No, but it works best when you do. Without them, answers come from the knowledge base and say so.
02Does anyone else see what I upload?
No. What you upload is used only for you. Nothing from one student's books is ever shown to another student or pooled into a common library.
03What can I upload?
Photos of pages, PDFs of up to 200 MB, and photos of your own marked answer sheets.
04Can I ask about a whole module at once?
Yes. You can ask about one line or about the whole file, such as what a chapter of your module covers.
05What does it cost?
