  1. Friday, the test.
    Sunday, the pile.

    Each answer sheet needs a careful read, a tick on every step and a total at the end. Then the next one.

  2. Snap the pages.

    Hold your phone over the pile and turn the pages. Vidhya picks up each page and files it under the right student.

  3. Vidhya reads the answer.

    Tables, graphs, rough work. It finds every step the student wrote.

  4. Each step gets a mark.

    Checked against your answer key, one step at a time. Where a mark is lost, it says why.

Disagree with a mark?
Change it.

Here Vidhya gave half a mark for the median. Look at the working and make the call: keep it, or give the full mark.

Q5 · Step 5Total 5.5 / 6

Reads the median from where the two ogives meet.

The working is right, but 17 is outside the accepted range for the median.

0.5/ 1

That’s all the checking left for you.

Marking

How does Vidhya know the right answer?

It reads your question paper and writes out the expected answer, with marks for each step. You check that answer key and approve it before a single answer sheet is marked.

Can I change a mark?

Yes, any mark on any question. You can leave a note to explain why.

Can it read untidy handwriting?

Yes. It’s built for real answer sheets: messy handwriting, rough work, crossings-out, diagrams and graphs. The original page sits next to every mark, so if something was misread you’ll spot it. Students can flag it too.

Do students have to write differently?

No. They write the way they always do.

Which subjects does it mark?

Every major school subject up to Class 12, from Maths, Science and Accounts to History, Hindi and Computer Science. Teach something else? Talk to us.

Getting started

When can I buy the ₹500 plan?

Very soon. Sign up for your free pages and we’ll message you on WhatsApp the day it opens.

What do I need?

A phone, the question paper and the answer sheets you want marked.

Do I have to install an app?

No, but the scanning app makes it much faster.

What does the scanning app do?

It spots each page as you turn it, sorts the pages by student and works in any light. A tabletop stand with a ring light is available separately.

Students and parents

What do students get?

Their marked answer sheet, a breakdown of every question and a way to ask you about any step. The student portal comes with the ₹500 plan.

Does anyone see results before I approve?

No. Students and parents see nothing until you press approve.

Schools and institutes

We have lots of teachers and classes. How does that work?
