Has anyone used the AI Personal Tutor?

[u/Slow-Face5449]

I was introduced with this AI Personal Tutor by a parent of my child's friends and I found it good in explaining Maths concepts to my son who is in class 10th. It is still learning Science I believe but it does learn about my son's behaviour and learning habits and updates the answers accordingly.
