Why Grasple?

Grasple is an online platform that enables teachers in Higher Education to find and create openly licensed exercises and easily share them with colleagues and students.

What makes us different from other online practice environments is that we are all about open collaboration.
What Github is for sharing and creating code, Grasple is for sharing and creating exercises in math and statistics.

Our mission is to make knowledge openly available to everyone.

To create a durable solution, we are structured as a social enterprise with an open business model. That means Grasple is free for individuals and paid for organisations that seek integrations and additional support.
