Why I built it

I’m Shyam Mishra, a parent and technology enthusiast. This project began with AI-assisted learning materials for my own kids and grew into a way to share useful resources with more students.

For students who want to strengthen their math foundations, I also created Math by First Principles, a free, no-ads math learning site.

How it’s made

I use AI to help develop the site and create, review, and improve its content. I’m responsible for what’s published, but mistakes can still happen.
