What is Demti?

A few years ago my mother showed me exercises that took her a lot of time to make by hand. I finally managed to turn them into a simple toolkit.

Demti is a side project of my company. Whenever I have time, I keep building it out step by step and add new features.

All of it is completely free, and everyone is welcome to use it and pass it on.

Do you have ideas or wishes? I'm always happy to hear from you!
