AI Tool That Grades Mock CBSE Board Papers with Step Marking, Looking for Student Opinions

So my boyfriend has developed this AI grader app for US and UK schools and unis, using the best AI models out there for grading. Recently i suggested him to do it for indian kids as well and well he had some queries and I need your help!

For context this grader is to check your FULL ANSWER SHEETS and not just one or two questions.

It will also give you detailed analysis of your solutions and compare it to the answers you wrote in your previous mock tests.

It does STEP MARKING, which is like the most important aspect when it comes to board exams.

Anyways so here are the questions;

1. When do you guys have your preboards?

2. ⁠Would this be really helpful for you or is it a waste of time in India? (He showed his app to some USA teachers and they loved it, hes now workinb on getting them to buy the subscription to it. He also showed it to his professors in IIT, who also said that it will help them grade papers in IIT)

3. ⁠if yes, how much are you willing to pay for it? (Coz its kinda costly for the app to grade answers)

4. ⁠Do you have any recommendations that he should put in the app aside from all the features already mentioned?

Thank you💝
